Burr‑free Drum Q355E Steel Left‑hand 55° For Lifting
Product Description
This drum is made of Q355E steel with 55° left‑hand rope grooves and burr‑free finished surface. Strict welding control is implemented to avoid porosity, sand holes and other weld defects, and reshaping is performed after welding. Vibration aging is adopted to eliminate internal welding stress, enhancing structural stability and reducing deformation risk. It is suitable for heavy‑duty lifting winch equipment to ensure smooth winding of wire ropes.

Advantages
Adopting Q355E steel with excellent low‑temperature performance and strong impact resistance, suitable for low‑temperature outdoor working conditions.
Vibration aging eliminates internal welding stress, effectively preventing long‑term deformation and extending service life.
Strict weld quality control without porosity or sand holes, improving overall structural strength and reliability.
55° left‑hand rope groove with burr‑free machining reduces extrusion and abrasion, offering good protection for wire ropes.
Matters Need to Attention
Inspect welds and rope-groove surface for dents and burrs before installation. Do not assemble until qualified.
Overload operation is prohibited. Match wire rope with 55° left-hand groove to avoid rope disorder and partial wear.
Under low-temperature working conditions, avoid shock load and frequent abrupt start-stop operations.
Regularly check tightening condition of connecting bolts and inspect welds for cracks.
Take protective measures during storage; avoid long‑term outdoor rain exposure. Prevent impact damage during handling.
