1. tower machine starts lifting guide support adding or falls tower to subtract while saving, and the bearing pin of jacking cross beam is shelved in the pin shaft hole of standard knot, the anticreep latch of jacking cross beam must be inserted in the anticreep pin-and-hole of standard knot, and be fixed in front groove.

2. to depart from standard knot while marking time completing a jacking step, jacking cross beam, must first anti-break pin be exited to standard knot anticreep pin-and-hole, be fixed in pit.(note: anti-break pin does not exit standard knot anticreep pin-and-hole, start lifting body rise by force crossbeam depart from standard knot mark time can damage anti-break pin).

In above-mentioned climbing support 4, for the ease of jacking installation and security needs, at climbing support 4 middle parts and upper position, be provided with platform 17, during jacking, staff stands on platform, and control hydraulic system completes the work of jacking, introducing standard knot and fixed tower bolt.

In tower crane of the present utility model, what driver's cab adopted is independent outlet structure, thereby the visual field is good, and inner space is large, to operator, creates good working environment.

In addition, in each standard knot, be equipped with the upper and lower cat ladder for people, and be provided with the platform of having a rest for people, and facilitate installation personnel and driver passing through up and down in the middle of tower machine.

In addition, load lifting limiter is also installed on slewing tower 9, in order to limit the biggest lifting capacity.

Beneficial effect: tower crane of the present utility model, by taking the measure of each side, improves the safety of tower crane greatly.And know very well the talent to guarantee the safe first element, therefore, in the design of tower crane itself, taked the measure of numerous hommizations, improve working environment, avoid the fatigue operation of operating personal, reduce human error, fundamentally improve safety.

The specific embodiment

Below in conjunction with accompanying drawing, describe the utility model in detail.

Referring to Fig. 1, tower crane of the present utility model comprises foundation 1, base pitch 12, tower-body standard section 3, climbing support 4, undersetting 5, pivoting support 6, upper bracket 7, driver's cab 8, slewing tower 9, tower cap 10, equilibrium arm 11, crane arm 12 and counterbalanced weight 13.Along with increasing of tower crane, adopt lifting body to introduce standard knot, then referring to Fig. 2, climbing support 4 comprises that jacking cylinder 14, activity climb pawl 15 and hydraulic power unit 16.The each lifting guide support adding of tower machine or fall tower and subtract when joint and all must use anti-drop device to guarantee safety, therefore on climbing support 4, be also provided with jacking falling-off prevention device, anti-drop device is comprised of two parts, and the one, the latch on jacking cross beam, the 2nd, the anticreep pin hole that standard knot is marked time.Specifically, referring to Fig. 4, jacking falling-off prevention device comprises jacking cross beam 18, anticreep latch 19, bearing pin 20 and front groove 21 and pit 22, referring to Fig. 3, on tower-body standard section 3, have and mark time 24, mark time be provided with above 24 pin shaft hole 23 and below be provided with anticreep pin hole 25.Its using method is as follows:
