We completed an order for a set of 20t
Electric Winch from
Chile. The winch was sent from Qingdao, China, to Valparaνso, Chile. The winch of this order is JM electric winch. The JM electric construction winch is a slow speed winch. There are many models of this electric winch, and the large tonnage winch also supports customization. The working principle of the winch The motor drives the wire rope drum through the reducer, retracts and unwinds the wire rope, and changes the direction through different pulleys. The technical requirements are mainly the speed of the drum, that is, the movement speed of the wire rope and the safety and reliability of the braking system. The winch is a relatively simple lifting or traction machine. Because it is used on the construction site for a long time, it is necessary to understand the performance and model in detail before using it
