当挖掘深大的基础坑和含水量较大的泥泞土壤时,采用拉铲挖掘机最为适宜。但拉铲的操作远比正铲复杂,需要有熟练的操作技术,掌握甩斗、拉斗、装土等各方面的动作,并且根据不同工程对象和不同土质采取不同开挖方法,才能缩短操作时间,提高工效,现将个人经验阐叙于下。 When excavating deep foundation pits and muddy soils with large water content, the use of dragline excavators is the most suitable. However, the operation of the dragline shovel is much more complicated than that of the forward shovel. It requires skilled operating techniques to master the actions in various aspects such as bucket throwing, bucket pulling, and soil loading, and different excavation methods can be used according to different engineering objects and different soil qualities to shorten the operation. Time, improve ergonomics, and now explain personal experience.
