Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a mobile auxiliary welding safety construction lifting machine. Background Technology

[0002] During the curtain wall construction of high-rise and super high-rise buildings, large metal transition components need to be welded at the bottom of the exterior balconies. Traditionally, cantilevered scaffolding is often used as a construction platform for welding. However, the cost of cantilevered scaffolding is relatively high. In some projects, high-altitude work baskets are used to carry out construction from the outside of the building, and hydraulic stackers are used to support the metal transition components to reduce construction costs.

[0003] However, existing small hydraulic stackers are relatively lightweight, while the weight of a single metal adapter is usually 60kg or even heavier, resulting in poor stability of the small hydraulic stacker during the lifting process and a risk of tipping over. To address this, we propose a mobile auxiliary welding safety construction lifting machine. Utility Model Content
