1. the tower machine begins lifting guide support adding or falls tower to subtract when 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 is fixed in front groove.
2. to break away from standard knot when marking time completing a jacking step, jacking cross beam, must first anti-break pin be withdrawed from standard knot anticreep pin-and-hole, be fixed in pit.(note: anti-break pin does not withdraw from standard knot anticreep pin-and-hole, start lifting body rise by force crossbeam break away 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, be provided with platform 17 at climbing support 4 middle parts and upper position, during jacking, the staff stands on platform, and control hydraulic system is completed the work of jacking, introducing standard knot and fixed tower bolt.
In tower crane of the present invention, what driver's cab adopted is independent outlet structure, thereby the visual field is good, and the inner space is large, creates good working environment to the operator.
In addition, be equipped with the cat ladder that supplies the people up and down in each standard knot, and be provided with the platform of having a rest for the people, and facilitate installation personnel and driver passing through up and down in the middle of the tower machine.
In addition, load lifting limiter also is installed, in order to limit the biggest lifting capacity on slewing tower 9.
Beneficial effect: tower crane of the present invention makes the safety of tower crane greatly improve by taking the measure of each side.And know very well that the talent is the first element that guarantees safety, 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
Describe the present invention in detail below in conjunction with accompanying drawing.
Referring to figure, tower crane of the present invention 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 as 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 also be provided with jacking falling-off prevention device on climbing support 4, 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. 3, jacking falling-off prevention device comprises jacking cross beam 18, anticreep latch 19, bearing pin 20 and front groove 21 and pit 22, have on tower-body standard section 3 and mark time 24, mark time be provided with above 24 pin shaft hole 13 and below be provided with anticreep pin hole 25.Its using method is as follows:
