Design tower crane TC7040
1. Quick introduction of TC7040
1.1 Functioning mechanisms
The efficiency of hoisting system, slewing mechanism, trolleying system and touring mechanism right impacts the total functionality of the tower crane. Consumers hope that the crane is secure and reliable in working. The principal aspect affected the steadiness of the crane is inertial effect and electric existing impact. “Mingwei” has solved individuals knotty problems with superior technology in the TC7040 tower crane.
1.1. 1 Hoisting mechanism
The hoisting system of the TC7040 tower crane is made to elevate 18 tons.
The hoisting mechanism lifting eighteen tons is adopted the frequency altering and stepless velocity controlled motor. Beginning and braking efficiently, it is quite outstanding to increase the system running stability, raise the precision of filling its footwear, simplify the operation, have no affect to electric powered network, prolong the element life time of the electric program, and extend the lifetime of the wire rope.
Using the frequency altering and stepless speed regulated motor and single-velocity-ratio spur equipment reducer, the system has basic construction, high dependability and simple upkeep.
Adopting the technology of large strong drum with LEBUS groove, it is quite useful to resolve the knotty dilemma of irregular orders when the wire rope is organized on the drum.
one.1. 2 Slewing mechanism
As opposed to EPT mechanisms, the inertial impact of the slewing system has the mo EPT effect to the crane. The a lot more the jib is lengthy, the more effect is fantastic. It cannot resolve the knotty difficulty with the conventional slewing system, which delivers about huge torsional pendulum effect on the crane. Right after the motor currently being run off, the jib operates for a lengthy time prior to stopping, guide to difficultly fill its sneakers and hurt the slewing reducer.
The distinctive technological innovation of frequency altering and stepless speed regulated is adopted in the schedule slewing system of tower cranes. The slewing mechanism starts off and stops smoothly, fil EPT its footwear fa EPT and properly.
1.2.3 Trolleying mechanism
The trolleying system, which impacts the load filling its footwear, is important system. Employing the technology of frequency altering and stepless speed regulated, the pace of the trolley adjustments in the selection of ~100m/min, it is really effective to minimize the operating effect and boost the running balance and doing work efficiency in TC7040.
