The original
energy chain consisted of a metal frame containing 4 lengths of
conduit.
All of
the motor cables, pendant unit cables and machine feedback cables
ran through these to the electrical cabinet.
The conduit
was generally in poor condition, and not adequately protecting the
cables. In addition, it had previously been found to be very time
consuming to replace damaged cable from within the conduit.
Robtec
recommended that during the machine relocation this energy-chain
unit be replaced by a heavy-duty Igus unit, with hinged panels to
allow easy access to the cables for future maintenance.
