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.
