ROLLING DRUM FOR CRANE

Crane rope drum introduction

Crane rope drum is a part of crane lifting mechanism which is used to full in, entwine, and store wire rope. The rope drum is consisted of drum shaft, flange type annular gear, drum hub, bearings, bearing pedestal, etc. Every part of crane rope drum is engineered and manufactured to meet the operational and safety requirements of industrial crane applications.

Crane rope drum basic requirements

Same rules should be shared by rope seat radius, tread diameter, and the sheaves.

Due to rope drums have grooves, the following parameters need your attention.

Minimum pitch is 1.2 times whir rope diameter.

Groove depth is 7/16’’ * rope diameter (minimum).

The pitch and groove depth lowers the possibility of rope damage caused by sharp “fins’’ between grooves.

Sheave wheel basic requirements

Depth of groove should be 1-0.5 times of wire rope diameter. Throat/ tread diameter is 24 to 30 times wire rope diameter.

Standard throat angle is 35°.

Rope seat radius equals to rope diameter and clearance, which should be support 135-150°of rope circumference and the surface should be slippery.

Wear can be measured with “Groove Gage”
