Industrial Grabs // Motor Clamshell Grabs

FELD-DELTA - MOTOR CLAMSHELL GRABS

The versatile universal grab

Design:

Drive unit:

Driven by three-phase AC or DC motor. The electric motor is switched via a reversing contactor and opens and closes the jaws electro-hydraulically depending on the direction of rotation. Reliable switching processes; control is carried out without solenoid valves. Overload protection through self-regulating hydraulics. Low overall height, compact construction. Secure retention of loads even in the case of a power failure, thanks to check valves.

Working cylinders:

High clamping force and high opening speed thanks to differential cylinders driving the jaws directly. Thanks to a special installation position, the cylinder is protected from damage on all sides. Corrosion-resistant piston rod thanks to special chrome-plating.

Jaws:

The jaws are interchangeable. Various shapes and sizes allow tailoring to the respective load. High degree of filling thanks to favorable top ratio. Robust design for low unladen weight. Long service life thanks to use of fine-grain structural steel and wear-resistant cutting edge sections.

Pivots:

All pivots are designed to be low-maintenance. Jaw synchronization with synchronization lever for clamshell grab. For the orange-peel grab, the jaws close independently of one another.
