igus GLV vertical cable guide

For highly dynamic applications in intralogistics, speeds of 7 m/s are no longer unusual. To ensure that vertically moving energy chains are safely held in place, igus has developed the guidelite vertical system (GLV), which combines safety with low weight and easy assembly for maximum motion dynamics. The open design also reduces the resonance and thus the noise.

For vertical applications, guide troughs are not necessary as long as the dynamics are low. The energy chain simply follows gravity. However, at speeds above 7 m/s, energy chains have to ensure safety in order to prevent accidents. Until now, virtually closed guide channels made of sheet metal were used as guide channels. However, these continuous enclosures are difficult and expensive to fit. In addition, the enclosed design creates a resonating body, which amplifies the operating noise of the energy chain.

The GLV uses open guide rails made of plastic with a system length of 2000 mm. This open design minimises the resonance and helps to keep the operating noise of the energy chain low. A further advantage is easy assembly, where a special screw ensures that the rails can be screwed with one hand and no counter-locking is required. If cables or energy chain get damaged — eg, by falling parts — the open design of the guide channel allows quick detection and easy access to the damaged area. The use of plastic rails also reduces the overall weight of the trough.
