AI Technical Summary
Technical Problem
Existing telescopic boom slider designs suffer from severe wear, boom vibration due to uneven contact, and high maintenance costs, and slider replacement is difficult.
Method used
The design employs a rolling slider, where the rollers and boom make rolling friction contact. Combined with a triangular plate, welding plate pin, and lubrication-free bearing structure, the rolling friction between the boom and the slider is achieved. MC nylon material is used to reduce material costs.
Benefits of technology
It improves the service life of the slider, reduces maintenance costs, enhances the stability and smoothness of the boom, reduces the entry of impurities, and lowers the resistance between boom sections.

Abstract
The rolling sliding block comprises a plurality of rolling wheels, the rolling wheels are rotatably installed on the inner sides of the arm head and the arm tail of the arm frame, and the rolling wheels are in rolling contact with the outer side of another arm frame installed in the arm frame where the rolling wheels are located. Rolling friction contact between the telescopic arm and the sliding block is achieved, the service life of the sliding block is prolonged, the maintenance cost is reduced, the telescopic resistance between the arm supports is reduced, and the arm supports stretch more stably and smoothly.
