What is it?

This is anonymous email sending script alexusMailer in text or html format with the ability to attach files. With ability to send a letter from any of the sender.

How it works?

alexusMailer sending through the SendMail (mail () function in php), the protocol allows sending letters without authorizing on the server, it gives you the opportunity to deliver a letter from any mailbox. The script is written in PHP5 and to send needs to have SendMail on your server.

Why you need alexusMailer?

For your convenience =). Sending software is very simple, alexusMailer provides easy to use interface and tools. It has email templates, macros, sending via the web shell (external servers), background sending.

Can't recieve emails!

In 99% of cases, the fact that the letter did not come to depend on the server that hosts the alexusMailer or shell through which they are sent. 1 Check the SendMail server (for example, check with technical support) 2 If alexusMailer send through the shells, make sure that the server is allowed network requests (php command "echo file_get_contents ('http: //google.com/humans.txt');" outputs "Google is built by a large team of engineers, designers, researchers ... ") 3: Check manually whether the server can send emails, php command: mail ("test@mailbox.com", "test message", "the contents of the test letters");

What is html(e) mode?

This is a variation of html mode, where all the pictures from tags and background attributes automatically downloading and attaching to letters, so when you open the letter it does not refer to external sites. This allows it to instantly appear in the e-mail clients and gmail.

What macro available?

Current web shell[OUTSERVER][OUTSERVER]All, during sending through web shells.
String macros be nested into each other and themselves. For example [([RAND]) * 5] Through a macro [FILE] in the "To" field, you can arrange to send letters to people from a file on the server. And a macro [URL] to send letters to people from a file from a remote server.

How can I send a huge amount of emails?

To send a really large number of letters one server becomes small. alexusMailer provides tools to send over multiple servers. Manage external server through the shells:
  • wso2
  • ARS (remailer script - shell replacer, in box with alexusMailer)
  • r57
  • c99
Shells can register on the relevant page of settings, multistring format:
Path to shell|shell type|password from the shell
In cases when a shell has password and login use this format
Path to shell|shell type|login from the shell:The password for the shell
On the Configuration tab of external servers is available quick check of shells, it checks that the addresses are correct, passwords match, and themselves shells execute commands.

If the delivery is carried out via the shell, then from the server where there is already very yaPosylalka letters are sent. If you want to send e-mails from the server and upload it to the shell and add it to the list of shells.

Just to increase the success of delivery you can experiment with the parameters of delay and number of threads.
Warning! If you use web shells you need upload "shell" folder
Warning! Shell modules of r57 and c99 can be detected as mallware, in this case not upload them.

What is web shell?

This tiny script helps in remote server management. It is more convenient to automate many tasks, as well as often faster than access through the console or through FTP. Shell can be obtained by downloading one of the options from the internet and uploading to the server. Or you can buy it on some forums which sell servers that are already have installed access via the shell.

What is threads and how can I use them

Threads is somewhat parallel dispatches messages. Suppose you have 8 messages that must be delivered and 4 threads. Running newsletter, each thread would be getting the letter, (left to send 4) when some of them end up shipping it will take another (left to deliver 3), and so on, until all the letters will not be delivered. Timeout affects each thread separately, ie if the timeout is set to 10 seconds, then each thread will send an email to wait 10 seconds. External servers(shells) are taken alternately, because if you set the number of threads equal to the number of shells you can get the maximum upload speed (but maximum mortality of shells), with such heavy use shells will break down quickly. But this can be avoided by setting a sufficiently large delay. When sending the background flows are used, possibly in the future, this will be changed.

How can I use background sending?

Enable this option in the settings. Fill in all fields mailing settings (from, additional fields, external servers, timeout), and then click "Send". alexusMailer will launch a background process on the server to send, it will not happen instantly please be patient. After about 5-8 seconds to begin alexusMailer will updated progress bar and sending log. If you refresh the page or close the browser and return to the page later you find that delivery did not stop, and is on the server in the background. You can stop the sending by clicking the "Stop". If the server on which alexusMailer will restart delivery stops. In the next versions we plan a way to automatically restart the background process.

How set password on alexusMailer?

On the Security tab in the Settings, enter your login and password and click "Set Password". To reset your password click on "Remove password" or set a blank username and password. Also on this tab is available to set HTTP proxy that alexusMailer can use to interact with Shell.

Visual editor breaks my code!

Visual editor tries to validate you code (make it correct by all standards), but sometimes you not need it. I this case you can edit you email in source mode (button "<>"), when you click Send\Preview from this mode, validation will be skiped.

How can I personalize my emails?

For personalization you can use this tools:
1) Write recipient in extended format: Recipient Name <recipient@email.com>
2) Set additional fields in recipient string in format:
My Recipient <recipient@email.com>;ADD0;ADD1;...

How use alexusMailer with Image Randomizer?

You can use script with image randomization software - Image Randomizer. You can use api link directly in your html code tags for Image mode and alexusMailer macro [URL:api link] for mode "Img tag" and "Background+css" mode. In first case enough to place macro in place where you requere your image, in second you need place it as attribute in the tag of your choice: div, table or aother.

Liebherr develops augmented reality app

Liebherr has developed an app for augmented reality (AR), bringing virtual construction sites to life.

It is available free of charge on all AR-enabled Apple and Android devices

The Liebherr AR Experience projects digital 3D data onto your real-life surroundings with the help of augmented reality. Three different virtual construction sites can be anchored on any horizontal surface in the room and viewed from any perspective.

“Every desk, every windowsill, every bar counter or every floor can become the stage for the Liebherr AR Experience,” Liebherr says. “Different scenes that run like a three-dimensional film can be played for each construction site. Here, the observers become the camera crew.”

The app has been developed by Liebherr-Werk Nenzing, the part of the group that makes piling rigs and crawler cranes in Austria. The app therefore contains scenes and content relating to heavy lifting, material handling and deep foundation work.

Difficult, complex tasks are presented and explained, simply and comprehensibly, Liebherr says.

Using the augmented reality app, you can experience how the HS 8200 duty-cycle crawler crane handles an extremely heavy dragline, for example. In fact, more can be seen using the app than in reality since with the LRB 16 drilling rig it reveals not only what is happening above the ground but also below.

Liebherr’s AR app is available from the Apple App Store or Google Play Store.

10 Important Heavy Equipment for Construction Projects

There never seems to be an end to construction projects in China, where you’ll often see forklifts, wheel loaders, and tons of other equipment lining up the roads or scattered in construction sites.

This rings especially true if you live in the heart of the city or in an industrial area, where these engineering projects are in extreme abundance.

At one point, you might be confused about the equipment present in these places, and they’ll just start to blur into one another and you won’t be able to enumerate their names.

So, whether you’re a seasoned professional in this discipline who need a refresher, or whether you’re a beginner and thus need some enlightenment, then you’ve come to the right place. This post will explore some of the most important heavy equipment in construction projects.

The next time you find yourself in an engineering site, or when the time comes and you’ll be planning which equipment your projects might require, then you’ll know exactly which is which!


A crane is a lifting equipment that is equipped with a pulley, ropes, and chains. It can easily hoist and lower heavy cargo around the job site. Some cranes have arms that can be expanded to different lengths.

There are two major kinds of cranes available out there: fixed and mobile cranes. These two are further divided into several types.


A forklift is a medium-sized truck that is being used to lift and transport cargo for short distances.

As expected, there are various kinds of forklifts available in China. They come in different styles and sizes, and serve their own unique purpose.


An excavator is a massive construction equipment that comes with wheels or tracks. It has a bucket arm attached to its front. This arm can freely rotate to 360 degrees.

It is typically used to dig through the earth or to hoist heavy materials.


Loaders are designed to transport materials around the job site. The usual materials being hauled are asphalt, rock, debris, and construction waste. There’s also gravel, wood, and sand—when these raw materials already come in a substantial amount, they will also require a loader for easier transportation.

There are various types of loaders available out there, and choosing the best loader can be extremely invaluable for any construction project. It can definitely make your task quicker and more efficient.

Here are some of the common types of loaders:

Wheel Loader

Track Loader

Skid Steer Loader

Backhoe Loader

Dump Truck

A dump truck can be seen in almost every construction site. It has become so indispensable that it has already been labeled a heavy equipment.

Like several other types of equipment, a dump truck also comes in varying sizes; and the key for an efficient loading and unloading of materials lies in choosing the variety that best suits your construction project.


A bulldozer is mainly used for pushing and moving earth at a job site. It is also considered a crawler because of how their tracks are fashioned—these tracks allow the bulldozer to remain stable.

A ripper is fastened on its backside. This serves to loosen up the earth (such as soil and rock).

Bulldozers are robust machines that can operate even in rough terrains.

Concrete Mixer

A concrete mixer, as the name suggests, is used to mix cement, water, and other materials (such as sand and gravel) to form concrete.


Trenchers are used for digging ditches or trenches at the construction site. They bear some resemblance with excavators, and the only difference is that they are specifically designed to dig ditches. As you might expect, trenchers are vital in piping projects.

If you want something that can hasten the installation of wastewater or drainage piping, then trenchers are your best bet.


This is more commonly known as a road grader or a motor grader. They’re used for moving around a considerable amount of earth and ensuring that the surface is level, flat, and sufficiently smooth. A grader is especially essential in architectural and civil engineering projects (such as road work).

Similar to a bulldozer, a grader is also furnished with blades (which allow them to smoothen surfaces adequately and more precisely).


A scraper is used to seamlessly move dirt and other materials. However, they are not suitable for all construction sites and are more appropriate in vast and open areas where they can move around more swiftly.

Common Construction Equipment for Heavy Lifting

In any largescale construction site, there will always be a need for equipment that is specifically used for lifting heavy objects. Construction sites almost never run out of heavy lifting. Even in some smaller-scale projects, heavy-lifting equipment will always be a requirement.

There are many kinds of equipment used for heavy lifting, from Forklifts to giant strand jacks, there is a wide variety that has different uses. For those who want to know more about each construction equipment, here is a list of 4 construction equipment used for heavy lifting:


Also known as the lift truck, a forklift is a powered truck that is mainly used for transporting materials and goods. It is available in many variations and load capacities. The usual capacity of forklifts is between 1 to 5 tons. Some of the variations of forklifts, the ones used for extreme heavy lifting, can lift up to 50 tons of materials.

Forklifts can be powered either by fuels like diesel, gasoline, and propane or by electricity which usually means it would have its own battery. Forklifts are also customizable through many different attachments that can increase its functionalities.

In China, forklifts are one of the most usable construction equipment that is viable for other industries primarily in commercial storages.

Mobile Cranes

This list will include 2 kinds of cranes, one is the mobile one that is mounted on a truck for increased mobility, and the other one is a fixed contraption, for greater control and load capacities.

Mobile cranes are more commonly known by the names of its variations. These include rough terrain cranes, crawler cranes, hydraulic cranes, and a lot more.

Most of these cranes have very specific uses like the rough terrain cranes. These are designed particularly for off-road sites these are perfect for construction sites in rough terrain thanks to its all-wheel capabilities and incredibly durable rubber tires. They are known for their high maneuverability and lifting capacity.

Crawler cranes are tracked mobile cranes that is self-propelled when compared to the other kinds of mobile cranes, they are very quick to set up and boast a higher level of versatility. They usually have either telescopic or lattice booms.

Last of the common types of mobile cranes is the hydraulic cranes. It is considered to be the standard kind of hydraulic cranes because of how generalized its design is. It relies on hydraulics to perform its tasks. It is lightweight and flexible. It is the most often mobile crane that is used for short-term construction. It is also used in other various things such as rescue missions, and transport of non-construction materials.


One of the most common things seen on a construction site is the presence of various materials in large mounds; with cement, gravel, and sand being some of the best examples. When it comes to getting the job done, these materials would need to be transported from one point to the other–and that’s where this particular construction equipment comes in!

Loaders, or wheel loaders as they are professionally known, are fitted for any construction job there is, especially if the job is on rough terrain. Their wheels make it easier for any worker to traverse through the rough site and also come equipped with large mobile shovels, which can be used for loading large quantities of cement and gravel onto trucks.

Strand Jacks

For consistent heavy lifting that doesn’t need the mobility of cranes, strand jacks are the perfect option. It is a small contraption that relies on hydraulic pressure and strong steel wires to lift and move materials precisely. As compared to the other construction equipment mentioned in this article, strand jacks are small in size and relatively simple to operate. It is used mostly in areas where the size of cranes makes it impossible for them to reach it.

Strand jacks are also known to be the most sophisticated out of the other construction equipment that is listed in this article. This is because it relies mostly on complicated software to control it. However, to an experienced operator, using this system will look really easy

Key Takeaway

In every construction site, there is a plethora of equipment that has many different uses, when it comes to heavy lifting, the mentioned equipment is the most common and the most used out of the different construction equipment used for heavy lifting. When managing a construction project that requires heavy lifting equipment, choose the most practical among the list mentioned above!

Seven Kinds of Common Cranes

There are various types of cranes used in civil engineering construction works. A crane is a piece of heavy machinery that is a tower or platform that is equipped with cables and pulleys. They are used to lift and lower materials. The most common use of cranes is in the construction industry and heavy equipment manufacturing.

Different types of cranes are used under different circumstances and environment. Here are 7 crane types that are used commonly depending on the project, work objective and environment.

1. Telescopic Crane

A telescopic crane offers a boom that has a number of tubes that are fitted inside each other. Then hydraulic mechanisms extend or retract the tubes to length or shorten the boom.

2. Mobile Crane

This is the most basic type of crane and consists of a steel truss or telescopic boom mounted on some kind of mobile platform. This platform could be wheeled, a rail or even a cat truck. The boom is hinged at the bottom and can be raised or lowered by cables or hydraulic cylinders.

3. Truck Mounted Crane

These types of cranes are mounted on a rubber tire truck and provide excellent mobility. The outriggers will extend vertically or horizontally and are used to stabilize and level the crane when it is hoisting a load of materials.

4. Tower Crane

A tower crane is considered to be a modern form of a balance crane. When fixed to the ground, this type of crane will often give the best of height and lifting capabilities. They are also used when constructing tall buildings.

5. Rough Terrain Crane

The crane is mounted on an undercarriage that has four rubber tires and is designed to be use off road. The outriggers can extend vertically and horizontally to stabilize and level the crane when it is lifting a large load. These types of cranes are single engine meaning that the same engine is used to power the undercarriage and the crane.

6. Overhead Crane

These types of cranes are also known as suspended cranes. They are generally used in a factory and some are able to lift very heavy loads. The hoist of the crane is set on a trolley that will move in one direction along a beam, sometimes two beams. They move at angles to the direction along the elevated or ground level tracks. The tracks are usually mounted along the side of an assembly area.

7. Loader Crane

This is a hydraulically powered crane that has an articulated arm that is fitted to a trailer. A loader crane is used to load equipment onto a trailer. The crane can be folded into numerous sections and will fit into small spaces when not in use. The crane can be easily transported because of its capabilities to be folded.

Civil engineering uses many different types of cranes during a project. They can be used to move heavy equipment or machinery. Many types of cranes can quickly and easily move equipment into trenches or down steep hills. They can move large pipes from one place to another. Cranes are beneficial in the construction process for buildings, bridges and overpasses. They are an indispensable asset to the construction and engineering fields. So using proper type of crane is important in construction works.

How Does a Crane Work?

A crane is a mechanism that uses a collection of simple machines to both raise and lower objects, and also move them horizontally. They are always equipped with at least a winder; cables, ropes or chains; and sheaves. Both sheaves and the winder are a form of pulley.

What Is a Crane?


Cranes can use a combination of simple machines to gain mechanical advantage and lift objects. The first is the lever, used in the balance-style crane. The crane’s beam is balanced at the fulcrum, allowing it to lift heavier objects with a smaller amount of force. The second is a jib-style crane, which uses pulleys to achieve mechanical advantage (but note that all cranes use pulleys–in this case, the pulleys are the main source of mechanical advantage). The third way a crane can lifts objects is by use of a hydraulic cylinder, either directly or in powering a balance or jib.

Horizontal Movement

Horizontal movement in a crane can be achieved in one of two ways. The first is to mount the entire device on a rotating pivot, and simply to swing the load-bearing boom or beam around. This is very common in mobile cranes and also some fixed cranes used in construction. The second method is to roll the load back and forth on tracks along the boom itself. This is very common on the fixed cranes in ports and railroad yards.


A final consideration in how cranes work is stability. A crane is stable when the sum of all movements about the base equal zero. As a practical matter, this means the size of the rated load on a crane must be less than what it would require to tip the crane over. In the United States, a mobile crane can only lift 85 percent of what it would take to tip the crane over. That margin is to account for potential instability arising from what the mobile crane happens to be sitting on.
