：In high pile projects with prefabricated beam and slab structures,if prefabricated components cannot be hoisted by crane ships due to environmental limitations,a temporary bridge with a wide bridge deck and high load-bearing capacity needs to be built,and large crawler cranes need to be used for components hoisting.However,the high standard design of the temporary bridge will lead to a significant increase in construction costs,resulting in project losses.A walking type hoisting machine and supporting hoisting technology are developed around the idea of the hoisting machine walking at different elevations and operating sequentially in different zones,and the techology can achieve full range hoisting of prefabricated components.The hoisting machine can walk on pile caps,avoiding the problem of building high standard temporary bridge.The hoisting technology is applied in engineering practice,and it has advantages of safety,efficiency,economy,and environmental protection.
