Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a simple hoisting and transportation device for bridge construction near existing railway lines. Background Technology

[0002] During the construction of railway and highway bridges, especially when construction work is carried out near existing operational lines, construction safety and transportation efficiency become key factors in the design and construction process. Due to the continuous operation of existing lines, the safety requirements for adjacent construction areas are extremely high, especially for vertical operations, which are strictly restricted. To ensure operational safety, relevant management units usually impose clear height restrictions on the operating height of construction equipment, the mechanical running trajectory, and the hoisting process, limiting the intrusion of construction equipment into the safety clearance of operational lines.

[0003] In such constrained environments, traditional vertical material hoisting methods, such as tower cranes, truck cranes, or crawler cranes, cannot meet construction needs. The towering hoisting equipment may exceed the limits above the operational lines. On the other hand, traditional equipment requires a large layout and operating space, making it difficult to operate flexibly in narrow construction passages. In addition, the limited material transportation routes also result in low efficiency in moving materials from the storage yard to the construction site, and manual handling poses safety hazards and high labor costs.
