Excavator extended arm is divided into:
 
2-phase, three, four stages, extended arms. 2-phase is mainly suitable for sand soil, concrete construction such as transportation, highway slope trimming and river dredging dredging and construction foundation, the river, deep groove conditions such as mining operations, etc.; A three-stage, four-paragraph is mainly suitable for high-rise buildings bringing the dismantling of the assignments, etc.; An extended set of arm: suitable for desilting and berms. Such as installation, disassembly is simple and convenient. Cheap, high efficiency, the excavator extended adaptive extended set of arm extended arm of not more than 4 meters
