Description

Stable vertical telescopic structure

Technical Field

The present utility model relates to a vertical sliding mechanism.

Background

The prefabricated parts in the building industry are mostly quite heavy, and in general, of several tons, some prefabricated parts are even tens of tons in weight. The preforms are typically hoisted by a crane during installation. However, the large crane cannot be driven in underground pipe gallery and tunnel construction, special mounting vehicles can be used for quickly mounting prefabricated members, and because the underground space is limited, the hoisting devices of the special mounting vehicles are different from the crane, and basically adopt a multi-directional mechanical arm, but the common mechanical arm cannot bear the weight of several tons, so that the structure of the mechanical arm is reinforced or redesigned, and the tension and the precision during the mounting of the prefabricated members can be met.
