Rope sheaves

Deflection of ropes between winders and hoisting equipment.

In floor conveyor systems, the winder is located at ground level in a separate winder building at some distance from the headframe. The deflection of the hoisting rope between winder and hoisting equipment is performed by rope sheaves, situated on top of the headframe.

The sheaves are used to divert or deflect ropes between the hoisting machine and the hoisting equipment. Usually a rope sheave is connected to an axle which is attached to the frame structure via externally fitted rolling bearings.

Multi-rope KOEPE hoisting systems require an appropriate number of parallel-arranged rope sheaves, which qualify as "loose sheaves". As an alternative to externally fitted rope sheaves SIEMAG TECBERG also offer internally fitted rope sheaves. In this case, each rope sheave is installed on its own rolling-bearing unit at the fixed axle, enabling all sheaves to rotate independent from each other.
