1. Product Overview
The
Hydraulic Grab Converter is a hydraulic control core component designed specifically for grab equipment, used to achieve efficient hydraulic energy conversion and control of the opening, closing, rotation, and locking functions of the grab. This product uses high-strength materials and precision hydraulic technology to ensure stable operation in heavy-duty and high-frequency working environments. It is widely used in heavy-duty work scenarios such as port loading and unloading, mining, and scrap steel processing.
2. Product Details
Core Features
(1) Overloading design
-Adopting high-strength alloy steel valve body, with a pressure resistance rating of 35MPa, suitable for impact loads.
-High flow design (maximum 300L/min) ensures fast response of the grab bucket.
(2) Multi functional integration
-Integrated pressure compensation, flow distribution, and directional control functions, achieving multi action coordination with a single valve.
-Optional distribution fluid ratio control, achieving stepless adjustment of gripping force.
(3) Environmental adaptability
-Dustproof sealing design (IP67), suitable for harsh working conditions such as dust and humidity.
--30 ℃~80 ℃ wide temperature range operation, built-in oil temperature protection function.
(4) Energy saving and efficient
-Load sensitive design, on-demand fuel supply, reducing energy consumption by over 25%.
-Low leakage hydraulic circuit reduces energy loss.
(5) Safe and reliable
-Double pressure protection mechanism to prevent overload damage.
-Mechanical emergency manual control, capable of emergency operation in case of power failure.
