Waste industry excavators will handle heavy loads of scrap, recycling and other potentially hazardous materials day in, day out. And while there are many design and specification differences between the various models and manufacturers, the key choice that buyers will need to make is whether to opt for a wheeled waste industry excavator or a tracked unit. There are benefits and downsides to both, especially when it comes to investigating the second-hand market.
Tracked excavators are the ultimate off-road performers, capable of scaling slippery inclines and gaining traction in situations that would leave lesser vehicles floundering. This makes them suitable for use in scrap yards, landfill sites and recycling centres, where they may need to ascend piles of uneven materials to carry out work. However, the side effect of offering excellent traction is that they are both very loud when in operation as well as being heavier and less fuel-efficient than wheeled equivalents. Buyers will need to take this into account, especially if the excavator is going to be put to work on a site that borders a residential area where noise may be an issue.Overview
Better Buy Wheeled
Wheeled waste industry excavators are innately more manoeuvrable than their tracked siblings, as well as being capable of taking to tarmac surfaces without doing damage, which could be a real bonus when it comes to cross-site and inter-site transport. Poorer off-road performance means that wheeled excavators do lose points in the traction department, but as with any plant machinery purchase, there are pros and cons to be weighed up.
In both instances, a hydraulic boom arm with an attachment suited to a particular task will be featured on tracked and wheeled waste industry excavators. And it is necessary to consider the reach of the arm, the digging depth it can achieve and the maximum payload it can bear. Standard bucket attachments offer a degree of versatility, but waste management firms may prefer to select a model that features a grabber, which is especially useful for handling scrap metal and other rigid materials.
The undercarriage of a waste industry excavator will typically be subjected to more punishment from abrasive surfaces than machinery used in other sectors. And so when buying a second-hand model it is vital to inspect this and assess the state of repair of the equipment and systems from the ground up. Wear and tear to tracks or wheels will need to be analysed, as will the state of the hydraulics. This type of excavator will often be built with a hydraulically mounted cab, the height of which can be increased on demand to allow the operator a better vantage point, improving safety and practicality. The cab's condition is just as important as any other element, particularly on models which have seen many hours of use in waste centres, which are predominantly outdoors and thus exposed to the weather. Finally, supporting struts and outriggers must be well maintained so that a used waste industry excavator can represent a good deal.
