JKMD-3.5×4 (III) Low-Speed Direct-Drive Multi-Rope Friction Hoist
In March 2013, Jinmin Group won the bid for equipment procurement at Ping’an Coal Industry Co., Ltd. of Duanwang Group in Shouyang, Shanxi Province. In accordance with the technical specifications outlined in the customer’s contract, the company independently designed the JKMD-3.5×4 (III) low-speed direct-drive hoist. This equipment employs an interference fit between the spindle and the motor’s tapered sleeve, eliminating the need for a gearbox. The unit was manufactured and delivered to the customer in April 2014 and successfully installed and commissioned.
