14.7 Personal protective equipment

15 Description of the clamping device

The grepos-5X has been designed for accurately clamping unprocessed and processed
workpieces. A wide range of accessories ensures the versatility of the equipment.
The force is generated purely mechanically. The power gear ratio is linear across the whole
clamping range. In order to increase the clamping force, mechanical force amplification
has been fitted.
In order to achieve a larger clamping range, the spindle is operated with a telescopic
mechanism and is protected against dirt thanks to complete encapsulation.
The operating torque of the lever is approx. 50 Nm for a clamping force of 40 kN.
Applying too much force to the drive either by impact or with extended levers leads
to damage to the force element.
Mounting and removing the grepos-5X is quick and easy.

15.1 Function

The grepos-5X is a direct clamping device. The quick adjustment is operated via a hermetically
sealed thread. The force is generated directly in a linear manner, using force amplification.
The clamping forces are variable and can be adjusted between 5 and 40 kN using the setting
ring. The clamping range depends on the type of jaw used and is variable between 0 and
max. 275 mm (with adapter and swivel plate).
It is possible to extend the clamping range by using additional extensions.
