AI Technical Summary
Existing CFG pile reinforcement cage lowering devices suffer from problems such as reinforcement cage swaying, positioning difficulties, safety hazards, and low work efficiency during the hoisting process. In particular, under complex geological conditions, it is difficult to effectively hoist and position the reinforcement cage.
Lifting components are used to hang the steel cage on the top and bottom sides. Combined with auxiliary positioning components and hanging components, the steel cage is stably hoisted and positioned by electric push rods and motor drive, avoiding inertial swaying and improving safety and efficiency.
It achieves stable hoisting and positioning of the steel cage, improves construction safety and efficiency, reduces manual operation, lowers safety hazards, and is suitable for highway tunnel construction under complex geological conditions.
