侧卸式装载机是在普通型装载机基础上改制而成并可实现正向、左右侧向卸料的多功能机械,特别适用于隧道开挖和窄小场地的施工作业。不需要转向调头等操纵动作就可以顺利完成装卸料工作,大大减少了作业循环时间,提高了工作效率。根据隧道施工学习经验,从实际出发,本着安全可靠、经济性高和实用性强的特点,探讨隧道施工准备期间对侧卸式装载机选型应优先考虑的几个问题。 The sideloader is a kind of multi-functional machine which is made on the basis of common type loader and can realize the unloading in the right, left and right sides. It is especially suitable for the construction work of tunnel excavation and narrow space. Do not need to turn the steering operation and other operations can be successfully completed loading and unloading work, greatly reducing the cycle time and improve work efficiency. According to the experience of tunnel construction, starting from the actual situation, in line with the characteristics of safety, reliability, economy and practicality, this paper discusses several issues that should be taken into consideration in the selection of side-loaders during tunnel construction preparation.
