Balance ropes are used only in friction-type deep hoisting shafts (Koepe) as a balance for the rope weights. Without such balance ropes, the hoist ropes would start slipping on the traction sheaves at a certain depth because of their own weight. Therefore, the weight of the balance ropes must always be adapted to that of the hoist ropes.
To ensure a safe and troublefree operation over the long term, the following rope characteristics and/or ancillary conditions should be ensured:
- Rotation resistant rope construction (mainly if no deflection sheaves are used) to avoid twisting and/or tangling of the ropes.
- A suitable ratio between rope flexure and rope diameter
- A sufficiently flexible rope construction (increasing the maximum possible number of bending cycles and ensuring a safe rope flexure)
- Wire surface coating (corrosion protection) adapted to the prevailing conditions
Our range of products includes the so-called “34x7 Class” balance rope which is excellently suited for this application. Of course, the TEUFELBERGER balance rope can be delivered with different coatings.
