Sheave dimensions

 drum-sheaves-1-veropeThe sheave groove dimensions with reference to the rope diameter should correspond to:

r = 0,53 x d and

h = 1,5 x d at the flange angle > 45°

D/d ratio for sheaves. Minimum sheave dimension

for verope products is 20 times the rope diameter.

More favourable D/d ratio improves the service



Single layer spooling

The lay direction of the verope products should always be chosen opposite the winding direction of the drum.


Multiple layer spooling

Increasing rope length requires good solutionsfor controlled spooling onto the hoisting drum.


The following rope features improve the spooling:

  • First- and second layer spooled under tension (1 % to 2 % of M.B.L.)
  • Lang’s lay rope construction
  • Compacted outer strands and / or rotary swaged rope construction
  • Ropes with high form stability to withstand increased lateral pressure


Drum and Sheave spooling angle

The spooling angle can be reduced by using different drum designs. The spooling angle for rotation
resistant ropes should not exceed 2 °.
For non-rotation resistant ropes, the angle should not exceed 4 °.
