General Purpose And Customized Clamshell Orange Peel Type Hydraulic clamsell grab
Electro hydraulic grab is a kind of hoisting equipment equipped with hydraulic system including motor, hydraulic pump and driven by mains power to handle bulk cargoes. Electro hydraulic grab can be operated to open or close through motor forward rotation and backward rotation or hydraulic directional control valve.
The electro hydraulic grab is able to handle bulk cargoes such as sand, coal, mineral dust, mineral, concrete, household garbage, waste iron etc. under kinds of harsh work environment. Due ti its good adaptability, hydraulic grab is able to match kinds of hoisting equipment, such overhead crane, gantry crane, deck crane, excavator and so on.
Based on construction, the electro hydraulic grab is mainly devided into the following types: (1) Hydraulic clamshell grab (2) Hydraulic orange peel grab (3) Hydraulic timber grab (4) Hydraulic rectangular grab
The electro hydraulic grab is mainly consisted of frame, jaw, hydraulic system. (1) Frame: It is the basic part. Generally Q345 steel is adopted to ensure strength. (2) Jaw: The jaw is made of Q345 and the edge is made of high wear-resistance steel for stable performance and long service life. The jaw is connected to the frame by pin shafts. The jaw, especially for orange peel grabs, is able to open and close asynchronously. In case that something large blocks two adjacent jaws, the other jaws are still able to grab for more material instead of stopping. (3) Hydraulic system: The motor, hydraulic pump, valve block, pipes and hydraulic oil tank are fixed inside the frame. One end of the hydraulic cylinder is fixed on the frame and the other end on the jaw. The hydraulic pump drive the hydraulic cylinder to extend or retract to close or open the grab.
(4) Protection grade: Different according to working requirements and environment.
(5) Components brand: Chinese and international famous brand for option.
(6) Coating thickness: ~180μm.
