China Coal Fair Beijing 2019: Exhibition of the longwall support with the maximum cutting height of 8.80 m. Photo: Tiefenbach<\/figcaption><\/figure>\n<p>Tiefenbach Control Systems GmbH, Bochum\/Germany, has received a follow-up order from China to also plan and supply the second complete electro-hydraulic control system for the world\u2019s largest roof support system. The order from the roof support manufacturer Zhengzhou Coal Mining Machinery Group Co. Ltd. (ZMJ) has a value of approximately 2.7 M \u20ac and, in addition to the main hydraulic control system, once again includes all safety-relevant auxiliary valves. The total of 152 sets of roof supports with a height of 8.80\u00a0m and an individual weight of 100 t each will be the second set of the highest roof support ever built in the world and will be used by the customer China Shenhua-Group (Figure 1). Due to the extremely high demands made by the weight and size of the supports, mainly new and further developed hydraulic components will be used. The projected lead time is only about three months. The very short delivery time could only be realized in the planning stage, as more than 80\u2009% of the installed components are manufactured or processed within the Knapheide Group of companies. With the award of this contract, ZMJ and Tiefenbach are continuing their extremely successful cooperation of the past years.<\/p>\n<p>With this order, Tiefenbach is further expanding its position as market leader for electro-hydraulics in Asia, the largest market for mining products. More than 130 longwalls worldwide are now equipped with the electronic and\/or hydraulic technology \u201cMade in Bochum\u201d.<\/p>\n<p>Further information:<br \/>\nTiefenbach Control Systems GmbH<br \/>\n<a href=\"https:\/\/tibacon.com\/en\/\" target=\"_blank\" rel=\"noopener noreferrer\">www.tibacon.com<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tiefenbach Control Systems GmbH, Bochum\/Germany, has received a follow-up order from China to also plan and supply the second complete electro-hydraulic control system for the world\u2019s largest roof support system. &hellip;<\/p>\n","protected":false},"author":25,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[758],"tags":[223],"class_list":["post-10846","post","type-post","status-publish","format-standard","hentry","category-industry-news-issue-04_2020","tag-tiefenbach-control-systems-gmbh"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 -
