Preparation for jacking of standard section of tower crane

Before jacking, the mechanical system, electrical system, structural part and hydraulic system of the tower crane shall be inspected. The oil cylinder, cylinder beam, standard lug plate and supporting bearing of the jacking part shall be inspected.

The clearance between the sleeve roller and the main chord of the tower body shall be adjusted. Before jacking, all standard joints used for connecting the height shall be adjusted to the front of the introducing beam of the jacket frame with the lifting mechanism within the range of 10 meters, and the lifting boom shall be rotated to the direction of the introducing standard joint. Jacking process, do not turn the tower.

1. with top of special wire rope buckle will lift a standard section to turn down the introduction of the amount of the upper section (note that lift the standard ear plate direction and the direction of ear plate tower crane should be identical) introduced the four roller card axis insert link set inside.

 Rotate it 90 degrees that the lower part of introduction of roller card board under the standard section of the lower horizontal CHS, and then put on the introduction of beam, the other lift a standard section, adjustment range of the car to the appropriate position, make the top part of the weight in balance, the balance of the tower is not the moment to a minimum.

2. Start the hydraulic jacking system, put the lugs on both ends of the cylinder beam into the lug jacking groove on the upper part of the support section, and pay attention to retract the support shaft when jacking.

3, check the set between the tower and accessibility, in the ministries and correct, down the tower and the turntable 8 each link bolt, then the operating handle up top point set, integrated back into the bearing, the positioning of the turntable and standard section caused by convex sets are separated by 20 MM, observe whether the positioning convex sets and the turntable of concave hole is, in the event of a deviation must adjust the position of the range of the car for.

4. When operating the handle, the oil cylinder jacks up the upper structure to raise a step, extend the supporting shaft and bear it at the lifting lug plate at the lower part of the standard section. Put the lugs on both ends of the lifting beam of the oil cylinder into the lug plate groove, slightly jacking up a bit of housing and retraction the supporting shaft.

5. and then to the second step of the jack-up, to be the height of the oil cylinder stroke more than a standard section out of supporting shaft, and will be placed on the introduction of the standard on the beam section within the artificial introduction set, aim at the section below.

Pay attention to the top of the ear plate plan consistent with the following sections, a jacking point set, retract a supporting shaft, and slowly down set operating handles section to make a new standard in place, and good with the original standard section link below eight strong connection bolt.

6. Extend the supporting shaft, but above the jack lug on the upper part of the standard section, retraction the piston rod of the oil cylinder, put the two ends of the jack beam into the jack lug groove on the upper part of the standard section, and prepare for the next working cycle.

7. if you need to continue raising the tower, with a hook to lift one day with four import wheel standard on the introduction of beam section, first, must pay attention to in hoisting standard tower between turntable under the each main limbs and should be for at least a high strength bolt,

The range of the car can run within 10 meters range, adjust the range of the car position, keep the upper top of weight balance, to tear down and turn down the connecting bolt, go to the next cycle, until the height of the tower height reach need.

8. After the jacking is completed, the high-strength bolts between the standard section of the tower body and the down-turning shall be installed, and then the high-strength bolts shall be fully tightened to reach the preset tightening force.
