Heavy machines such as wheel loader, backhoe loader, dump truck, bulldozers, etc., are essential in a construction, public works company, in a quarry or mine and they should be used correctly, it must be handled by skilled personnel and periodically checked.
It is very important to know the operation of each component, to carry out the appropriate tests.
The backhoe loader is an essential machine in earthmoving works. Due to their (relatively) small size and versatility, backhoes are very common in urban engineering projects and small construction projects (such as building a small house, repairing urban roads, etc.).
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.
The employer is responsible for providing appropriate training for the works to be performed and all the relative safety devices related, which we showed in the following image.
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 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.
In many countries of central and northern Europe, as well as in North America, the winter and first snowfalls come by surprise very often. This event influences not only our living conditions in general but also our earth-moving, public work, mines, quarries, agriculture machineries such as excavators, loaders, dump trucks, bulldozers, etc. status.
