The three-stage mountain pulling arm is refitted for 12-15 tonnage machines. The length of the refitted is from 23-28 meters.The back-and-forth expansion time is basically kept at about 10 seconds for expansion, mainly for eucalyptus, pine and other economic forest farms, the weight of the grab is guaranteed to be less than 1 ton, and the length of the trees is not too limited. This design is the hidden design of the oil pipe, to ensure that the pipeline will not be hung by bushes, and will not cause the problem of pipe explosion. The forearm cylinder is double sleeve design, and the frequent expansion will not cause the shaking of the iron pipe, thus loosening the joint, resulting in the problem of oil leakage .
