Prodem crusher bucket

BPH Attachments is adding a new crusher bucket to its Prodem hydraulic attachments portfolio in the UK.

The PCB Prodem Crusher Bucket is designed to crush and convert waste material including brick, concrete, rock and wood, into reusable hardcore or infill, directly on site.

Suitable for excavators from eight to 55 tonnes, including, skid steer and backhoe loaders, it will be available to hire or purchase from BPH Attachments from the second week of 2020.

The bucket has a patented auto-reverse crushing drum with BPH reckons can increase productivity to anything between 34 to 45 tonnes per hour on-site by reducing operator input and increasing use of site machinery.

Features include intuitive jaw adjustment, high displacement radial piston hydraulic motors, wear resistant teeth, and easy forward-facing or reverse-facing loading.

BPH Attachments sales director Matt Bastable sayd: “We’re always looking for innovative products to add to our ever-expanding range, and our attachments portfolio has now increased by 35% in the last year alone. With further announcements due in the not too distant future, it’s an exciting time for the BPH Attachments.”

3 Ways Excavator Operator Training Pays Off

Imagine two identical excavators on the same job, tasked with the same work. While they may seem identical, after five years of use one will have a much higher resale value, will have burned far less fuel and required fewer repairs — all while accomplishing the same amount of work.

So what’s the difference? Operator behavior. The person running the machine can significantly impact total cost of ownership. That means deciding to invest in operator training should be as simple as the decision to purchase a superior machine. Here are three key areas in which operators can impact total cost of ownership, as well as a few tips on reducing operating costs.

#1 – Reduce fuel consumption

A good way to maximize jobsite fuel efficiency is to train operators on an excavator’s work modes. Many operators have a tendency to select the highest setting available, regardless of task. Often, however, the task could be achieved at a much lower RPM without any loss in performance or cycle times. Running at 200 to 300 RPMs lower could equate to a 10 percent reduction in fuel consumption.

It’s also important for operators to be familiar with built-in fuel-saving features, such as auto idle and auto engine shutdown. If the features are set to engage after a predetermined amount of time, instruct the operators not to override the settings.

Daily maintenance also helps. For instance, keeping the machine greased creates less friction. Smoother movements require less power and fuel.

When setting up for excavation, look for ways to minimize machine movement. For efficient loading, place the excavator at a bench height close to the height of the haul truck sideboards and in a position where it doesn’t have to swing and travel more than necessary

Regardless of operator behavior, Volvo does offer a fuel efficiency guarantee on many of our crawler excavators.

#2 – Reduce wear and tear

One of the major ways to reduce wear and tear is for operators to begin each shift with a walk-around — checking filters and fluid levels, and looking for any leaks, damage or loose hardware. They should also make sure the excavator is clean. Rollers that have debris and cannot turn freely can freeze up, causing wear on the tracks.

Don’t skimp on the grease. It’s cost-effective preventive maintenance that helps keep bushings, bearings and pins operating smoothly. Ignoring track tension can also be harmful. Loose tension can lead to excessive bushing and sprocket wear, and overly tight tensions can cause stress on the undercarriage.

Train operators to let managers know when alarm codes and maintenance reminders go off to help avoid unplanned downtime and more costly repairs.

#3 – Reduce idle times

Training operators to reduce idle time can slow depreciation and reduce maintenance costs. While it is not uncommon to have idle times as high as 50 percent, it is possible to cut that idle time in half in many cases — a reduction that could have an enormous impact on resale value.

For example, let’s compare two machines — one with 50 percent idle time (Machine A) and one with 25 percent idle time (Machine B). Machine A is likely to run about 2,000 hours per year, whereas Machine B is closer to 1,500. Over five years, Machine A has 10,000 hours compared with 7,500 hours for Machine B. Machine B also would require around five fewer 500-hour service intervals over a five-year ownership period. This could equate to a $20,000 difference in resale value, depending on size class.

The fleet manager’s role

A good operator-training program is one that includes ongoing monitoring by fleet managers to track progress. Telematics can also play a role in comparing operator behavior. For those fleet managers who do not have the time or resources to monitor this type of data, they should consider turning to a dealer or manufacturer who offers an active machine monitoring and reporting service.


Keeping Your Rubber Tracks Moving

Rubber tracks are used on excavators (https://www.julyparts.com/shop/) and other tracked vehicles to minimise ground damage. They’re very good in this regard and you can be sure that you won’t be leaving a wasteland behind your machine. The main issue, in fact, is keeping the rubber tracks in good working order.

These tracks take a lot of wear and tear when compared to steel tracks. Although they’re very durable, they need some maintenance and attention, preferably whenever there are time and space to do it. This regular care reduces overall maintenance time, taking care of minor issues to prevent a bigger workload later.

Rubber Tracks – Care and Maintenance Tips

To care for and maintain your rubber tracks, you need to know what to expect. Different types of terrain can cause different problems but can predict some issues before they happen and deal with them easily.

For example:

  • Mud and debris: Materials of this type are taken up by the tracks, which clogs them. It’s not good for the tracks over time. The easy fix is a thorough clean and removal of the mud, preferably ASAP.
  • Undercarriage and assembly: These areas, being under the vehicle, also take up a lot of mud, dust, and small debris. It’s best to check the undercarriage regularly and ensure that there are no significant deposits of materials on them.
  • Uneven wear: This type of wear is caused by more pressure being put on one track than another, often during repetitive work. The unevenness of the tracks affects performance. It’s best for operators to avoid the usual practice of locking tracks. Make turns with the vehicle, rather than locking, to avoid uneven wear.
  • Inspect the machine before operation: Your machine can start up and instantly have problems because of some minor difficulty with the tracks. It’s a good idea to check the rollers and driving sprockets for any issues before operation. Driving sprockets are also very prone to accumulating materials, due to their shape. Be patient, but quick, when fixing any problems.
  • Track tension: Over-tension in tracks can be a serious problem. The tracks, if stretched too tightly, react to pressures and impact much more than at a slightly loose tension. This can do damage to alignment and increase wear on the tracks. Stick to a specified level of tension and “track sag”.
  • Common sense: The other simple and very effective way to care for your tracks is to simply stay alert and be aware of any unusual movements or sticking, or similar behavioural issues. While it’s important to be vigilant, don’t try to DIY-fix anything that looks like a complex issue. Get it checked out by your service people for the best results.
