This invention discloses a mountain environment crane and its construction method, relating to the field of crane construction technology. The mountain environment crane includes a lower traveling body and an upper slewing body, with the slewing part of the upper slewing body rotatably connected to the slewing seat of the lower traveling body. The lower traveling body includes a track mechanism and a width adjustment mechanism. The width adjustment mechanism is mounted on the slewing seat, and the track mechanisms are symmetrically arranged on both sides of the slewing seat. The width adjustment mechanism is located between the paired track mechanisms, and its output end drives and connects to the track mechanisms. The width adjustment mechanism is used to adjust the distance between the paired track mechanisms. This mountain environment crane and its construction method enable the entire machine to travel on soft and rugged terrain by means of the track mechanism, and the width adjustment mechanism allows for flexible adjustment of the spacing between the paired track mechanisms, adapting to travel operations in narrow sections and improving the overall passability of the machine.

The utility model relates to mechanical drive technical field especially relates to a chain drive belt tensioner. Wherein, one end of casing is connected in guide rail, and the inside wall of casing is slidably provided with the mounting piece, and the smooth surface tension wheel is rotatably arranged on the mounting piece, one end of the adjusting rod passes through the other end of the casing and is connected with the mounting piece, and the other end of the adjusting rod is exposed to the casing, the adjusting rod can drive the mounting piece to move along the axial direction of the adjusting rod, the locking piece is screwed with the adjusting rod, and the locking piece can abut against the outer surface of the casing. Compared with the prior art, the chain drive belt tensioner adopts the smooth surface tension wheel, when the tooth clamping and the phenomenon of jamming occur, the movement of the chain drive belt changes from the rolling form to the sliding form, without affecting the movement of the chain drive belt, which can prevent the chain conveyor from jamming, avoid the phenomenon of tooth skipping and asynchronization on both sides, and prevent the chain conveyor from jamming, being stuck and being broken.
