The properties of durable special GRP material introduced into its chain links allows for long unsupported travel, producing a chain with high torsion rigidity that allows for high speed travel and acceleration, yet is easy to maintain. In addition, cross stays and clips made from a flexible plastic allow quick and easy maintenance and cable access without the need for tools.
Explaining that steel, stainless steel and plastic materials provide different advantages, Kabelschlepp believes that materials can be combined to produce hybrid carriers, such as combining GRP plastic chain bands with aluminum stays.
“It is the application that determines the proposal for a specific cable carrier and the materials used. Our customers have a choice,” explains Marcus Richards, the company’s engineering manager.
The specification of a cable carrier system is predominantly determined by technical parameters, such as dimensional requirements, accessibility of the compartments, the unsupported travel to cover or the additional loads to be managed.
Stefan Engel, engineer and product manager at Kabelschlepp, stresses that when considering choice of materials, the company looks at various factors. “Balancing these parameters varies in each single application,” he claims.
These parameters include extreme operational conditions that can trigger excessive wear, such as mechanical loads and the working environment, as well as energy efficiency; reducing friction with plain bearings may allow for smaller drives, motors and frequency modulators, thus saving cost and ultimately the environment.
