The difference between electri hydraulic grab and rope grab.
When the material resistance is greater than the excavating force of the grab, the grab is clamped up and closed. While the electric hydraulic grab is a power grab, when the material resistance is greater than the excavating force of the grab, the grab can not handling material, but the motor still rotating, an the output grab is the max power attempt to overcome the resistance, the result is useless, the grab "suffocated" in the material.
The hydraulic grab is fitted with an open structure, which is usually driven by a hydraulic cylinder, and a hydraulic clamshell composed of a plurality of jaw plates is also called a hydraulic claw. Hydraulic grab is widely used in the special equipment of hydraulic type. Such as hydraulic excavator, hydraulic lifting tower, etc...
The hydraulic grab for excavator is divided into two types: rotary and non-rotating. The non-rotating grab used for the oil way of grab oil cylinder, without adding hydraulic valva block and pipeline. The rotary grab is to be controlled by adding a set of hydraulic valve blocks and pipes.
