1 概述1959年美国首先开发轮式装载机。由于土石方工程要求施工机械机动灵活,近年来轮胎质量又得到不断提高,促使了轮式装载机的发展。轮式装载机一方面向大型发展,斗容达10.3m~3(矿山开采达13m~3);另一方面向小型发展,斗容仅0.26m~3,并且向多用途发展,如具有铲雪、集装木材等功能。 1 Overview The United States first developed wheel loaders in 1959. As earth and rock projects require the construction machinery to be flexible, tire quality has been continuously improved in recent years, which has prompted the development of wheel loaders. On the one hand, the wheel loader develops to a large scale, with a capacity of 10.3m~3 (mining up to 13m~3); on the other hand, it develops to a small scale with a capacity of only 0.26m~3 and develops to multi-purposes such as shovels. Snow, containerized wood and other functions.
