Description

Technical Field

[0001] The utility model relates to the technical field of road construction hoisting, and more specifically to an auxiliary stabilizing structure for a road construction hoisting trolley. Background Art

[0002] Road construction equipment lifting refers to the process of using lifting devices to lift heavy equipment, materials or components to a designated location during road construction and maintenance, and formulating a detailed lifting plan, including the selection of cranes, lifting paths, lifting points and safety measures.

[0003] Since most lifting devices use steel ropes for lifting, when the equipment is lifted and placed, factors such as human touch and wind may cause the equipment to deflect significantly. Depending on the size of the equipment, sometimes personnel need to stay away from the lifting equipment to ensure safety, and the use of manual assistance may also pose certain safety hazards. The free deflection of the equipment affects the accuracy of the equipment placement. At the same time, the rotating equipment will cause the steel rope to twist, causing a certain burden on the steel rope, and in severe cases, it may cause the steel rope to break.
