轮胎式装载机自从二十年前作为主要铲装设备在国外露天矿使用,特别是十多年前出现7.6米~3以上的大型设备以来,其使用范围越来越广,已取代了很大一部分3～4.6米~3电铲。一些条件适宜的中小型露天矿山常常把它作为采剥主铲,而一些大型露天矿大多采用斗容大于7.6米~3的挖掘机与轮胎式装载机配合作业,斗容7.6米~3以下的挖掘机所完成的工作量逐年减少。斗容3米~3以下的电铲几乎消失了。 Since its appearance as a major shoveling equipment in open-air mines in the world 20 years ago, the use of the wheel-loader has been largely replaced by that of large-scale equipment with a displacement of 7.6 to 3 more than 10 years ago Part of 3 ~ 4.6 m ~ 3 electric shovel. Some small and medium-sized open-pit mines with suitable conditions often regard it as the main shovel, while some large-scale open-pit mines mostly use excavators with a bucket capacity of more than 7.6m3 to work with the wheel loaders, with a capacity of 7.6m to 3m Excavators to complete the workload decreased year by year. Bucket capacity of 3 meters to 3 the following shovel almost disappeared.
