L68B2 Mast Section Hydraulic function of Tower lifting equipment
The system is mainly composed of hydraulic pump stations, hydraulic ceiling cylinders, lock valves and high-pressure hoses. When the tower ceiling is lifted, the system needs to carry more than 30 tons of weight of the tower suspension superstructure. The system operating pressure reaches 18 Mpa or more., belongs to high-pressure hydraulic system. The system has the advantages of small size, light weight, high specific power and smooth operation, but at the same time, it has low transmission efficiency and is prone to failure.
Since the hydraulic overhead system of the tower crane belongs to the sealed pressure pipeline circulation system, the flow of oil in the pipeline, the movement of the parts inside the hydraulic components and the damage of the seal are not easily detected, so it is difficult to analyze the cause of the failure and determine the fault. The parts are difficult. There are many tower crane accidents, half of which are caused by improper disposal after the failure of the system. In order to avoid major equipment accidents, how to prevent the failure of the hydraulic ceiling system has become an urgent problem to be solved.
