The square tube leading screw lifting Lever  is designated for lifting antenna and other communication devices in the wild. It could not only be installed on the vehicle but also used on the ground. The lifting lever adopted the techniques of synchronous spiral rotation transmission structure of the leading screw, synchronous lifting of multi sections of the mast, small screw rise angle, which ensure the lifting lever could stop accurately at any point within the effective height range. The unique design also enhances the stability, reliability and safety to the great extent. The adoption of the distinct technique of spiral rotation of the leading screw makes the spiral rotation change to rectilinear motion, which achieves high thrust by small torque and reaches great reduction ratio by working as the speed reducer. The lifting lever features small volume, large load, fast lifting speed, simple operation, wide application and could work at random indicated height. Moreover, the structure of the lifting lever is square, which makes the product could be installed in various types of carriers. The series of the lifting lever includes different height products, such as 5m, 7m, 9m, 12m, 15m, 18m, which could meet the different requirements of customers.
