EH (Electro-Hydraulic Grab)
Electro-Hydraulic Motor Grabs are specially designed to handle bulk materials with single-rope cranes and require a power supply from the crane. The handling performance of electro-hydraulic grabs, is depending on the supplied electric power, converted by hydraulic pumps on the grab. The optimum required filling degree for different materials to be handled is reached by high closing forces.
For dredging and digging purposes, grabs come with heavy duty parts and special design. According to requirement, additional equipment or accessories can be added. For submerged jobs, the grab comes with closed motor.
The grab control system is usually operated from the crane operator cabin, where it is integrated, but a remote control option is also available on demand.
