WORKING PRINCIPLE OF THE GRAPER

The grab device implies its installation to a load-lifting crane or any similar equipment.
Attachment grapple equipment differs between models in terms of the kinematic feature, according to which all devices can be divided into equipment:

• rope - the jaws are mounted to the drive winches with the help of a flexible rope;
• drive - the working mechanism is located directly on the equipment.
• Drive captures can be divided into types of working equipment and energy

sources. According to this criterion, grabs are:

• motor - function from engine energy;
• hydraulic - work from the hydraulic system of special equipment;
• electrohydraulic - a pump powered by electricity is located in the upper part of the unit;
• pneumatic - they require a pneumatic network.

The technical characteristics of Greifer determine the specifics of his work, as well as the special equipment that is recommended as a base.

Attached equipment - a grapple can:

• be installed on loaders, cranes, excavators;
• hang on the hook of a crane;
• to work from a stationary pneumatic system
