Electric-Hydraulic Bulk Grab is an efficient tool for loading and unloading sands, coal, mineral powder and bulk chemical fertilizer. Electric-Hydraulic Bulk Grab has hydraulic power and control system itself. The grab uses constant output pump and servo system. The flow of pump can change by itself according to working pressure. When the pressure reaches the max pressure, the flow is almost zero, so it can reduce the overflow, and reduce the temperature rise of oil. The cable rollers are improved designing, the temperature rise of rotating parts will be not higher than 35℃ when it is on full load working, which can ensure the grab can work continually.
1、The grabs have high dead weight.
2、The spaces between the shells are relative small to minimise the risk of material loss.
3、The grab hydraulic cylinders are fitted with replaceable piston rod protections and are hydraulically cushioned.
4、Wide opening ranges guarantee a good penetration and release behavior.
