ABSTRACT:
The invention refers to a hanging control device connected to a unit to be managed, specifically control switches or hanging control panels in order to control hoisting gear, by means of a control line, whereby the control line contains electrical lines (2) to transmit control signals and strain relief, which is supported at the top of the unit to absorb weight and traction forces.In order to create a hanging control device for which the length of the control line can be easily changed, we suggest that strain relief be created by means of hose (6), which can be folded flat and has the design of a type of textile hose, and that electrical lines (2) run through the inside of the hose.
