Description

TECHNICAL FIELD

[0001] The utility model relates to a crane hoisting technical field, concretely relates to a hoist subassembly for concrete block. BACKGROUND

[0002] Hoisting refers to the installation, positioning of equipment by cranes or hoisting mechanisms, and is a general term for hoisting equipment, workpieces, tools, materials and other objects during maintenance or repair to change their positions. Hoisting is generally performed by cranes. The working process of a crane generally includes lifting, running, lowering and returning to the original position. The hoisting mechanism lifts the heavy object from the pickup location by the pickup device, moves the heavy object through the running, rotating or amplitude changing mechanism, and then lowers the heavy object at the designated location and returns to the original position.

[0003] Concrete, commonly known as "concrete", refers to an engineering composite material formed by cementing aggregates with cementitious materials. The main raw materials include cement, limestone, sand, gravel, etc. Among them, the density of cement and limestone is relatively large, so the weight of the obtained concrete block is relatively heavy. Many construction sites often need to transport concrete blocks to better perform construction. The hoisting mechanism such as crane is generally required to lift and transfer the heavy concrete block. After most existing cranes hoist and move the heavy object, the connecting structure (mainly the steel wire rope connecting the concrete block) is still hanging on the hook, and the connecting structure needs to be manually removed. Each hoisting needs to be removed once, which leads to low hoisting efficiency, waste of time and manpower. Moreover, the existing crane generally has only one hook, and can only hoist one or a group of heavy objects at a time, such as one or a group of concrete blocks. Under the premise of larger load capacity of the crane, the hoisting efficiency is low. CONTENT OF THE UTILITY MODEL
