Siemag Tecberg followed this in September 2012 with the award of an order for a high-capacity shaft-hoisting system for Jincheng Anthracite Mining Group's Zhengzhuang coal mine in Shanxi province. Centered around a 6 m-diameter, 3.5 MW winder, the system will have a 51 mt payload. This contract again illustrates the company's longterm relationship with Jincheng Anthracite, which began with the delivery of a high-performance brake system. Between these events, the company presented its mobile winch to customers at its factory at Haiger in August. Supplied to Xinwen Coal Group Co., the winch is mounted on a four-axle truck and is equipped with two rescue cages for carrying up to four or 10 people each on two decks. The 1,300 m-long rope includes a communication cable in its core. VDMA Air-powered Lifting Expertise from JDN J D Neuhaus GmbH & Co.
