Installation
4.1.4

Hydraulic turning device (optional)


There must be a universal joint between the hydraulic turning device and the crane boom or fork
sleeves, because the device must have the possibility to swing in each position of the crane boom or fork
sleeve.

If this there any restriction in these swinging, mechanical damages could occur.

On the top of the hydraulic turning device is a swing damper to restrict the amplitude of the swinging
and to attenuate.

Hydraulical connection

4.2.1

Installation on carrier/lifting equipment


According to hydraulic circuit diagram there is a valve block in the both circuits, which ensures that the
products do slide of the device at pressure loss.

The connection to the carrier/lifting equipment may be accomplished only by qualified personnel.

The device is equipped with a back pressure valve in the hydraulic circuit, which prevent the load from
falling down at pressure loss.

Connection the device to the energy supply system be sure that the environment is free of dirt and that the
connecting hoses are free of abrasion and don not stuck in outstanding parts, while moving.
4.2.2

Hydraulic circuit


To use the device two separate hydraulic circuits for main clamping and side clamping (three circuits with V-
Equipment or turning device) are required.

By the use of supplementary equipment, like a rotating motor or a displace unit, the number of the required
hydraulic control circuit increase.

Is there only one (two) hydraulic circuit on the lifting apparatus, you can split one of the circuits by using an
electromagnetic valve ELMV.
