AI Technical Summary
Existing hoisting technologies cannot vertically hoist building materials with protruding structures to the target floor, and inclined hoisting methods pose safety risks.
Design an adjustable counterweight balancing lifting device, including a lifting frame and a counterweight. One side of the lifting frame forms a cantilever beam, and the counterweight is installed on the side away from the cantilever beam. The counterweight is driven to slide along the slide rail by an electric winch and a wire rope to adjust the lifting balance and ensure that the cantilever beam is in a horizontal state when lifting materials.
It enables safe and efficient horizontal hoisting of materials in raised structure buildings, avoids spatial conflicts, improves hoisting efficiency and safety, and adapts to the construction needs of different raised structures.
