Description

Technical Field

[0001] The utility model belongs to the technical field of building hoisting, and in particular relates to a load transfer and monitoring device for a vehicle crane outrigger. Background Art

[0002] After the construction of the basement of a high-rise building is completed, it involves parking the mobile crane on the basement roof or structural floor for related lifting work. It is necessary to review and verify the bearing capacity of the floor under both the walking and lifting conditions of the mobile crane, especially the lifting condition is the most critical. During the lifting operation, the top plate is usually unable to withstand the concentrated load applied by the legs. The legs should be placed on the structural columns or beams according to the reaction force of the mobile crane legs to meet the corresponding bearing capacity requirements and ensure the safety of the lifting operation. When conditions are limited and the legs must be placed on the top plate, corresponding reinforcement measures such as temporary supports extending to the bottom plate of the structure are usually set up. The temporary support is relatively cumbersome to set up. When the mobile crane is in a displacement condition, the use of reinforcement measures will greatly reduce the efficiency of the upper lifting operation, and the economy is also poor.
