Lifting steel frame construction platform used for bridge pier work

This creation department has a lifting steel frame construction frame platform for the work of bridge piers. The hydraulic lifting equipment system drives the lifting steel frame construction frame platform and the formwork system to rise and fall. The lifting steel frame construction frame platform is It is assembled and dismantled on the ground, which eliminates the need for construction personnel to disassemble and assemble at high places, effectively shortening the construction period.

As shown in Figure 1, it is a conventional construction frame used for bridge pier work. Each ascending stage is supported by a mobile crane auxiliary lifting assembly. The construction frame is placed on the four sides of the pier column. The manpower is located at the top of the upper edge to form the construction frame and formwork. When dismantling, the movable crane is used to assist the hoisting to remove the formwork and construction frame at the top of the high place. The construction frame is manually removed from top to bottom, and finally lifted by mobile crane. Remove the parts to the ground.

As shown in Figure 2, it is a conventional construction frame used for the construction of bridge piers. Each rising stage is assisted by mobile cranes to hoist and dismantle the formwork. On the side of one side of the construction pier, separate personnel are installed. In the ascending phase, the construction frame, the formwork and the upper and lower equipment are assembled by the manpower at the top of the upper edge. When the maneuver is removed, the template at the uppermost edge of the high place is removed by the mobile crane. The upper and lower equipment of the personnel is removed from the top to the bottom by manpower. With the mobile crane, the removed equipment is placed on the ground.
