Floor openings from climbing concrete placing boom

Boom used, perpendicular to the ground to be built on each floor of the opening required to build a building of the same size, and boom will be fixed therein. Imposed load boom, boom when the building has been built to a certain height and floor plate having sufficient strength to withstand being allowed to climb along the opening. It can reach a height depends on the speed of construction of buildings, which usually climb a whole floor height (should be 3.5 meters) each time. When theconcrete placing boom or climbing, their workload from the floor around the opening, but mainly in vertical loads climbing frame emission.

Since the boom is ready to crawl along the floor were open. The steps are as follows:
Boom (1) manual valve mountaineering be treated to achieve. The operator stands on the floor openings are specially constructed fabric machine climb and climbing frames are positioned for the next, next extended or retracted to control climbing cylinder.
(2) selector switch on the console & NBSP; "self-climbing" position to start the motor, and then to extend the operation of the manual valve cylinder upwards so semi-circular hole in the upper part of the cylinder piston head hit the top of the shaft in the tower. Kept extending until the lower portion of the lower frame of the top shaft loosened cylinder, then remove it.
Above the cylinder manual valve (3) when the shank extends 500mm, allow engagement hole in the lower frame to the tower, and then insert the lower part of the top shaft.In this case, hydraulic cylinders and retract boom will fall from the top of the low shaft support it. Remove the top of the upper shaft, and insert it in another hole in the tower.
(4) extend cylinder manual valve handle, so half hole in the piston head hit the upper part of the shaft at the top of the tower. Kept extending until the lower portion of the lower frame of the top shaft loosened cylinder, then remove it to start the second mountaineering trip & NBSP; & NBSP; repeating the above operation, the boom will rise up along the climbing frame.
The ground climb boom cylinder cycles required depends on the height of the ground. For example, a 3-meter-high floor needs 5 cycles.
(5) After completing the climb, tightly iron wedge wedge means climbing frame. Vertical forces from the boom is in the lower part of the tower to the top of the shaft to pass the lower frame, and the horizontal force is composed of two up and down climbing frames.
The selector switch in the boom are transferred to the control station before pouring the concrete "work" position.
Finally, disconnect the hose from the pipe fitting cylinder climb the tower on the platform plate, and place it on the platform and the tower portion of the platform for use on another portion of which in the future.
