2Function and application

When the compressed air is ports are pressurized

alternately, the piston moves backwards and forwards

in the tubing. By means of a rigid connection, the

outer slide also moves. The slot in the cylinder barrel

required for this is covered by a band system.

Fig. 2Circuit symbol

The DGC is intended for the space-saving transport of

masses.

Both the slide mode and the yoke operating modes

are permitted (observe loading limits).

Unpressurised movement of the slide is permitted

only for fault elimination and at low speed. If the

speed is too high, the resulting partial vacuum can

pull the sealing band into the piston chamber. This

leads to:

–severe leakage and

–impermissible accelerations (e.g. with a vertical

mounting position).

3Transport and storage

Note

Avoid touching the guide rail with your hands during transport und storage.

Otherwise the layer of grease will be damaged.

Consider the weight of the DGC.

Depending on the design, the DGC weighs over 150 kg.

For transport, the transport belts must be spaced according to the permissible

support distances (support distances è Fig. 6).

4Requirements for product use

Note

Malfunctions will occur if the device is not used correctly.

Be sure to always comply with the specifications in this chapter.

Note the warnings and instructions on the product and in the relevant operat

ing instructions.

Compare the maximum values specified in these operating instructions with

your actual application (e.g. forces, torques, temperatures, masses).

Only observance of the load limits allows operation of the product in compliance

with the relevant safety regulations.

Take into consideration the ambient conditions at the location of use.

Corrosive elements in the environment (e.g. ozone) will reduce the service life of

the product.

Please comply with national and local safety laws and regulations.

Use the product in its original state without any unauthorised modifications.

Remove packaging, such as foils and cardboard.

Exception:

–The plastic cover on the aluminium guide rail (with DGC-…-G/GF).

The packing is intended for recycling (except for: oiled paper = general waste).

Make sure that the compressed air is properly prepared è 11 Technical Data

Take the tolerance of the tightening torques into account. Unless otherwise

specified, the tolerance is ±20%.

5Installation

5.1Fitting mechanical components

Avoid pushing in or sucking in the sealing band.

Damage to the sealing band reduces its reliability in operation. Jerky movement

of the unpressurised slide can cause a partial vacuum that sucks the sealing

band into the piston chamber.

Leave all screws and threaded bolts in their original states, unless you are

requested to modify them in these instructions.

Do not allow the band system to become damaged or excessively dirty.

Damage to the DGC will reduce its reliability and service life.

Make sure that the device is fitted free of mechanical stress and distortion.

Use the foot mounting adapter HPC to mount the DGC on the end caps.

Turn the mounting screws until they are equally tight.
