HOISTING TECHNOLOGY_proof 19/07/2016 13:37 Page 2 HOISTING TECHNOLOGY The new valve block upgrade was developed because many of the valves that were used on the Bosch Rexroth station are obsolete and not available on the market and there is no new replacement for them. Instead of having to install a complete hydraulic unit, ABB now offers mining customers “the chance to upgrade to the latest technology in an easier and more cost effective way.” ABB says that the installations of the new valve block have proved to be very quick with minimum downtime and virtually no loss of production. “The customer benefits are that the spares are readily available and cheaper and that if the customer also has a new hoist system with an ABB TUBE hydraulic unit, the same valves are used, hence there is no need to stock different brands.” SIEMAG TECBERG’s benchmark reference in China At the start of 2016, Tianjin SIEMAG TECBERG delivered mine winder equipment to the HUIZE lead & zinc mine, part of the Chihong Group based in Yunnan Province, China. It was the first order for large hoisting equipment into the noncoal industry for SIEMAG TECBERG’s local subsidiary in China.  Detlef Scheppe, Executive Vice President Business Unit Hoisting Technology at SIEMAG TECBERG told IM: “The HUIZE mine winder combines SIEMAG TECBERG’s renowned cutting-edgetechnology in hoisting equipment with the mine’s requirements of stretching the operational envelope for hoisting in China. With a depth of 1,500m and hoisting ore and personnel from multiple levels, the HUIZE lead and zinc mine needed high-end technology and control to ensure the safety and reliability of the hoist.” Chihong Group is controlled by Chinese state owned company Yunnan Metallurgical Group and is the largest lead and zinc ore mining and smelting company in Yunnan Province. Over the past 50 years, HUIZE mine has made a significant contribution and brought strong economic benefit to the Chihong Group and its other investors. “HUIZE 3# shaft was therefore a key project for the deep resource development, and making the first steps into deep mining was an important milestone for Chihong.” Scheppe states; “HUIZE has become the flagship project to watch for many other mining The Tianjin SIEMAG TECBERG mine winder system at Chihong’s HUIZE lead and zinc mine achieved stable running and no-load operation by end June 2016 companies in China, which also plan to develop their deep resources in the coming years. SIEMAG TECBERG first became involved in the project following a technical exchange meeting in 2012 together with Chihong Group & Changsha Design Institute. Both parties wanted to invite the best available hoisting system suppliers to provide the best technical solution in their HUIZE 3# shaft.
