How to detect problems in the fluid system of wheel loaders, bulldozers, dumpers and excavators

Efficiency is a key issue when we talk about the operation of excavators, loaders, dumpers, bulldozers, etc.

The owners of heavy machines and their operator use fewer resources to complete certain jobs than others, certainly have a competitive advantage because they use the equipments more effectively.

Scheduled and preventive maintenance, which we always recommend to be carried out regularly, is the best ally to avoid breakdowns and damage to the machine.

In this article we will deal with a very important topic, namely how to detect any contamination in the fluids present in a heavy machine.

The operator’s safety of excavators, wheel loader, dump truck, bulldozer: fundamental labours standards and good practices

Excavators, wheel loaders, crawler excavators, bulldozers, backhoe loaders, etc. are special vehicles that perform heavy jobs with certain features. Operators must be properly trained and educated to the use of all the components of the machine, especially the engine, transmission, hydraulic system, electrical system, etc., and follow the safety standards defined by the legislation and by the company.

How to preserve the hydraulic system of earth moving machines

The hydraulic system of a machine determines how much weight it can load and at what speed it can operate. Therefore, it represents one of the fundamental elements for the correct functioning of a wheel loader or an excavator.

In the next video we can appreciate how, thanks to the hydraulic system, the excavator’s arm and the bucket move easily.

Operators must obtain the maximum possible performance of the machines to use them in the best way and avoid wastage of fuel.

This objective can only be achieved through the implementation of a failure maintenance and prevention strategy. The checking must be carried out daily and, in the specific case of the hydraulic system, must mainly be focused on the hydraulic oil level. The filters and oil must be changed in accordance with the manufacturer’s instructions.

Fuel consumption on wheel loaders, excavators, bulldozers, dumpers: technology and saving advice

Fuel is one of the basic elements of earth-moving machines. Saving fuel should be one of the main objectives of any operator, both for economic reasons but, above all, for environmental reasons.

The public works and the exploitation of quarries and mines, today, as ever, must be “sustainable”, which means that a balance is needed between the satisfaction of current needs and the well-being of future generations without compromising it.

The Bucket: the most important implement in earth-moving operations

Earthmoving works require the use of appropriate equipment. Implements, such as the bucket, the hammer, the clamp, etc., meet precise requirements, giving enormous flexibility to the machines.

Thanks to the bucket positioner it is possible to change the implement quickly, without excessive effort and in totally safe.
