Cable guiding device
Type cable collecting basket
The trailing cable is coiled into a basket. U-shaped guides with
plastic springs along the hoistway guide the trailing power cable
between the cable collecting basket at ground level and the
cable attachment on the car.
Type cable trolley on separate guide rail
To be able to control the cables and to overcome the voltage
drop in the power cable at high lifting heights, the power cable
and control cable are fixed firmly to the mast from ground level
to a junction box in the mast halfway to the mast top.
The trailing power cable and the control cable from the junction
box to the cable brackets on the car are tensioned by cable
trollies. The cable trollies travel on a separate guide rail
attached close to the mast from ground level to a point halfway
to the mast top.
Differential expansion/contraction of the power and control
cable requires that the two trollies are not mechanically attached
to each other.
The method described above is also used for hoist installations
in harsh surroundings with highwinds, low temperature etc.
