What Is A Wheel Loader

Date:Mar 17, 2021

Wheel loader is a kind of shovel and transportation machinery widely used in roads, railways, ports, docks, coal, mines, water conservancy, national defense and other projects and urban construction. It plays an important role in reducing labor intensity, speeding up project construction, and improving project quality.

Its main function is to shovel loose materials and short-distance transportation operations. It is one of the fastest growing, production and sales, and market demand models in construction machinery. We usually see the wheel loaders the most, and the opposite is the crawler loaders. Compared with the crawler type, it has the advantages of good maneuverability, no damage to the road surface, and convenient operation. Therefore, wheel loaders are widely used.

Loaders can be divided into: power system, mechanical system, hydraulic system, and control system. As an organic whole, the performance of the loader is not only related to the performance of the mechanical parts of the working device, but also related to the performance of the hydraulic system and the control system. Power system: The driving force of the loader is generally provided by the diesel engine. The diesel engine has the characteristics of reliable operation, hard power characteristic curve, and fuel economy, which meets the requirements of the loader's harsh working conditions and variable load. Mechanical system: mainly includes walking device, steering mechanism and working device. Hydraulic system: The function of this system is to use fuel as the medium of the mechanical energy of the engine, convert it into hydraulic energy by the oil pump, and then transfer it to the cylinder, oil motor, etc. and convert it into mechanical energy.

Control system: The control system is a system that controls the engine, hydraulic pump, multi-way reversing valve and actuators. The hydraulic control drive mechanism is a device that converts small power electrical or mechanical energy into powerful hydraulic and mechanical energy in a hydraulic control system. It is composed of hydraulic power amplifier components, hydraulic actuators and loads. It is the core of static and dynamic analysis in the hydraulic system.
