Zhifang Machinery has successfully finished the factory friction performance and overload acceptance test for our heavy‑duty friction‑drum winch. The whole testing procedure went smoothly, and the unit passed customer witness‑based inspection on site.
To verify the winch's reliability under extreme working conditions, the customer required a 1.3‑times rated load overload test. During the test, the equipment completed repeated traction, loading‑holding and running cycles under 130% of its nominal load. Key items including friction drum transmission performance, gear meshing condition, brake responsiveness, structural deformation and electrical system stability were fully examined.
The large‑size friction‑drum winch features heavy‑duty gear transmission structure, robust welded base and large‑diameter friction drums. It is widely used for ship‑yard slipway launching and haul‑out operations, capable of long‑distance continuous rope‑arranging towing. Every critical component was closely monitored throughout the whole overload test. No abnormal vibration, over‑heating or structural defects occurred in the full test process.
On‑site customer representatives witnessed the whole test procedure and completed formal acceptance. Satisfied with the winch's mechanical performance and overload resistance, the customer confirmed that all technical indicators meet contract requirements.
This successful 1.3‑times overload test fully proves the mechanical strength, safety redundancy and stable traction capacity of Zhifang's friction‑drum winch. Prior to delivery, all our winch products will undergo strict load‑simulation testing to minimize potential failure risks for end‑users. Zhifang Machinery keeps delivering reliable customized winch solutions for shipyards, marine‑engineering and heavy‑industry clients worldwide.
