Crane Sheave Minimum Diameter Calculator

Strictly compliant with ISO 16625:2013, this crane sheave minimum diameter calculator rapidly works out the minimum sheave pitch diameter by wire rope nominal diameter and mechanism working class. Undersized sheaves risk rope dislodgement and safety threats, while oversized ones limit lifting height and load capacity. It verifies compliance, optimizes sheave selection, predicts wire rope lifespan, reduces maintenance costs, avoids downtime and improves operational safety & efficiency.

Crane Sheave Minimum Diameter Calculator
Formula

D2≥h2×t×d

  • D2: Minimum pitch circle diameter of the sheave
  • h2: Sheave selection factor (ratio of sheave pitch circle diameter to nominal
    diameter of the wire rope)
  • t: Wire rope type factor
  • d: Nominal diameter of the wire rope

Notes

The selection coefficients for sheaves and balance sheaves differ depending on the
type of crane, and calculations must be performed based on the specific circumstances:

  • For hoisting and boom hoisting/luffing wire ropes used in general cranes and hoists, bending fatigue is often the primary form of wire rope damage when single-layer winding is employed. The above coefficients are particularly recommended to limit radial pressure on the wire rope in the rope entry and exit areas.
  • For mobile cranes, the above coefficients are particularly recommended when single-layer winding is employed to limit radial pressure on the device and enhance resistance to bending fatigue.
  • For mobile cranes, the above coefficients are particularly recommended when multi-layer winding is employed to limit radial pressure on the wire rope in overlapping areas and the resulting wire rope torsion effect.

Applicable Cranes

  • Overhead travelling cranes
  • Hoists- wire rope
  • Portal or semi-portal cranes
  • Portal or semi-portal bridge cranes
  • Mobile cranes
  • Cantilever cranes (pillar, jib, wall or walking)
