Application of GRAEFF sensors in construction machinery.

GRAEFF solutions for earthmoving machines

Construction machinery

Construction machinery is an important component of the equipment manufacturing industry.

We refer to the mechanical equipment required for earthwork construction projects, road construction and maintenance, mobile crane loading and unloading operations, and comprehensive mechanized construction projects for various building projects as construction machinery.

It is primarily used in fields such as national defense construction projects, transportation infrastructure construction, energy industry construction and production, mining and other raw material industry construction and production, agricultural, forestry, and water conservancy construction, industrial and civil building construction, urban development, and environmental protection.

GP Series Pressure Sensors

Due to the harsh working environment of construction machinery, it is necessary to effectively control the overall performance of the machinery in order to improve its safety and performance. In recent years, with the rapid advancement of construction machinery manufacturing technology, sensor technology has become more widely used in construction machinery.

GRAEFF sensors are mainly used in three areas: engine condition control, hydraulic system control, and overall performance control of construction machinery.

GRAEFF Pressure Sensor

Hydraulic transmission systems play a crucial role in the transmission mechanisms of modern construction machinery. They are not only used in primary working mechanisms, such as the digging mechanism of excavators and the vibrating mechanism of vibrating rollers, but also extensively applied in the travel systems, steering systems, and various servo mechanisms of modern construction machinery. Pressure sensors used in hydraulic systems primarily serve to achieve closed-loop control of hydraulic oil pressure. However, not just any pressure sensor can perform this task. When the control valve spool suddenly moves, it can generate peak pressures several times higher than the system's operating pressure within an extremely short time. In typical mobile machinery and industrial hydraulic systems, if such extreme operating conditions are not considered during design, any pressure sensor will be quickly damaged. The overload and shock design mechanisms of GRAEFF's specialized pressure sensors for construction machinery provide a comprehensive solution.
