AI Technical Summary
The steel cables of traditional construction material transport cranes do not have anti-sway function for the basket, which causes the basket to tilt during transportation, resulting in the spillage of building materials and affecting transportation efficiency.
The system employs a bidirectional threaded rod driven by a clamping motor and a support clamping plate structure. Through the cooperation of a sliding plate and a push-pull rod, it achieves front and rear limit clamping of the suspended platform. Combined with the synchronous operation of the swivel casters and the lifting motor, it ensures that the suspended platform remains stable during movement.
It effectively prevents the suspended platform from tilting due to inertia and wind force during movement, ensuring stable transportation of building materials, avoiding material spillage, and improving transportation efficiency.

At present, the construction material transport hoist usually adopts a steel rope to suspend and hoist the hanging basket loaded with building sand materials, and then moves and transports in the construction site. Since the steel rope is a flexible structure, the suspended hanging basket swings in the transportation process due to the influence of moving inertia and wind force, which causes the hanging basket to tilt and the sand materials inside the hanging basket to spill outside. Therefore, the traditional construction material transport hoist steel rope does not have the function of preventing the swinging of the hanging basket, which causes the sand materials to spill outside the hanging basket and seriously affects the transportation efficiency of the building construction materials.
