With the development of building and installation engineering and national defense industry, the long arm excavator has been widely used in engineering practice. The advantage is that it has great bearing capacity in small amplitude, and has long operating distance and high operation height under the condition of permissible load. Telescopic boom is mostly used in construction vehicles or other conveyance. Here are the features of the long arm excavator.
1. The effective operation distance is large and the operation height is high. Through telescopic boom structure, the distance between targets can be achieved. The height of the arm can reach a higher height, which is unmatched by traditional excavators.
2, it can load and unload the goods directly over some obstacles. The long arm excavator uses the telescopic arm device to carry out the loading and unloading operations across the trench, the step and the door and window holes. Because of the negative angle of amplitude, it can also make the ditch clearing or repair, leveling and so on, so it is more suitable for use in the field conditions.
3, the long arm excavator has better operation safety performance. The telescopic boom excavator has the function of load expansion. It can stop at the position far from the stacking point on the uneven pavement, open the stable leg, and use the telescopic and variable amplitude action to complete the loading and unloading operations of the goods; it is also convenient to clean and disassemble the furnace in the steel making workshop.
