Electric Hydraulic Double Disc Grab
Introduction
Grab Bucket with opening and closing structure, usually driven by a hydraulic cylinder, composed of multiple jaw hydraulic claw also called hydraulic claw. Hydraulic grab in the hydraulic special equipment more widely used, such as hydraulic excavators, hydraulic lifting tower.It is an efficient tool could replace manpower for Bulk Cargo,such as Ore mining Ore,Coal mine, grain.
Electric Hydraulic Grab Bucket are specially applied in charging & discharging of sand, waste steel & big stones. These grabs cab be executed with open or closed shells depending on the job & the type of material to be handled. The grabs are manufactured of high wear resistant steels. All bearings are heavy duty & sealed for high performance. The grabs can also be designed with the hydraulic rotator for 360 Deg. Rotation.
Feature
1. The capacity is from 5 CBM to 20 CBM;
2. Control distance is 200 meters;
3. Grab material is Q235B and Q345B (ASTM A6);
4. Single steel rope to lift grab is enough, specially for Deck crane or Portal crane;
Advantage
The grab has its own hydraulic system, and the main components of the hydraulic system, such as valve groups, seals, valve blocks, etc., are all European and American brands. The hydraulic pump adopts a constant power pump and adopts a hydraulic servo system, and the change of the system pressure can effectively control the output of the pump. When the maximum pressure is reached, the flow rate of the pump is extremely low, which greatly reduces the overflow, reduces the energy consumption, and reduces the oil temperature, so as to utilize the continuous work for a long time and greatly improve the production efficiency. The grab bucket is simple in structure, easy to operate, and can work in various harsh environments. The unique jaw curve is particularly conducive to the loading and unloading of various bulk cargoes. The upper part of the grab bucket is provided with a cable interface, which is convenient for connection with the crane.
