一、需要发展电动铲运机 近二十年来,以柴油机为原动机的铲运机,由于具有机动灵活、生产能力大等优点,在井下金属矿山迅速发展成为主要装运设备,但因废气净化问题未能彻底解决,且近年石油供应紧张,要求节约能源,因而对电动铲运机的采用,显著增加。少量小型电动铲运机已使用了多年,五年前开始在大于3.5米~3斗容的铲运机上装备电动机,现在国外又制成4米~3的电动铲运机。美国Wagner和西德GHH公司还研制了举升能力为12吨,斗容为6米~3的大型电动铲运机。
First, the need to develop electric scooter In the past two decades, diesel powered engines scraper, due to its flexibility, large production capacity, the rapid development of underground metal mines into a major shipping equipment, but due to the issue of exhaust gas purification However, the shortage of oil supply in recent years has led to the demand for energy conservation. As a result, the adoption of electric scrapers has increased significantly. A small number of small electric scrapers have been used for many years. Five years ago, electric scrapers equipped with scrapers of more than 3.5m3 were equipped with electric motors, and 4m ~ 3 electric scrapers were made abroad. Wagner and West Germany GHH companies have also developed a large electric scooter with a lifting capacity of 12 tons and a bucket capacity of 6 meters ~ 3.
