2026 05/25

The transmission line winch play the kernel role in transmission line pullers, it is the primary rotating drum for the steel wire rope and realizes traction and elevating for power construction as the winch wheel in power construction. This MARSHINE Powered Pulling Winch has the following characteristics High efficient winch wheel construction-roof specially designed series suitable for outdoor over head line work with a very large traction-pull force stable over a wide range of job applications. It has a rated low-speed traction force of 50 kN, which is enough for heavy-load lifting and tensioning procedures, besides, it obtains a 45 kN medium-speed working traction power for an ideal tradeoff between the power of operation and the efficiency of construction under normal line-stringing situations. In addition, the equipment operates at high speed up to 33 m/min in no-load traction, it is featured with rope-retrieve at 7.3 m/min in reverse which help rapidly handling of rope and moving of positioning.

The utility cable winch has a winch drum groove with a standard diameter of 240 mm. This design provides a close fit to the standard steel wire rope to prevent slippage during working under high strength. Harnessing the power of a 9 kW diesel engine running at 2000 rpm, the MARSHINE Capstan Winch Machine provides solid, dependable and continuous rotational power from the winch drum at even at off-grid construction sites. With the precision gear transmission, the winch drum operates steadily and smoothly, with low noise and less mechanical wear. It contains built-in automatic safety braking mechanism which instantly Locks in case of failure offers strong protection for Construction Safety.
