Product Description

Product Overview

This steel spiral‑groove wire rope drum is core hoist spare part for double‑girder overhead crane trolley. The precision‑machined spiral groove achieves smooth and neat rope arrangement, avoiding rope jumping, disorder winding and premature wire‑rope abrasion. We supply standard and non‑standard drums according to drawing or technical data, widely used for QD‑type double‑beam workshop cranes.

Key Features

✅ Smooth rope‑arrangement design: CNC‑machined continuous spiral groove, keep steel rope winding orderly.

✅ High‑strength steel: Q235B/Q345B carbon‑steel body, good rigidity, anti‑deformation under heavy load.

✅ Wear‑resistant groove surface: High‑frequency quenching HRC45‑55, longer service life for drum & wire rope.

✅ Strict quality control: Ultrasonic welding inspection, full dimension check before shipment.

✅ Two supply options: Bare drum body only OR full drum assembly with shaft, flange, bearing housing.

✅ Full customization: OD, length, groove size, connection interface all customizable.
