Catalogue ZH excavator boom arm.pdf
The tunnel arm is used for construction in narrow space. Due to the small space of tunnel engineering and subway engineering, the original large and small arms cannot operate normally. The tunnel arm is also called shortened arm, which is shorter than the original large and small arms. It can work flexibly in a narrow space and the working radius is reduced. At the same time, in terms of redesign, the tunnel arm is more suitable for large-scale crushing hammer, and the middle arm oil cylinder is placed below to protect the oil cylinder from crushed stones.
The excavator tunnel shortening arm, the tunnel special shortening arm, and the special short arm after special modification according to the working conditions of the tunnel, can be equipped with an enlarged bucket.
The special arm for the tunnel is made of high-strength manganese steel material, which can cope with the harsher crushing environment.
