QTZ315(7040-16)

Construction tower crane TC7040
1. Brief introduction of TC7040
1.1 Working mechanisms
The performance of hoisting mechanism, slewing mechanism, trolleying mechanism and Traveling mechanism directly affects the whole performance of the tower crane. Users hopeThat the crane is stable and reliable in working. The main factor influenced the stability ofThe crane is inertial impact and electric current impact. "Mingwei" has solved those knottyProblems with advanced technology in the TC7040 tower crane.

1.1.1 Hoisting mechanism
The hoisting mechanism of the TC7040 tower crane is designed to lift 18 tons. The hoisting mechanism lifting 18 tons is adopted the frequency altering and stepless speedRegulated motor. Starting and braking smoothly, it is very outstanding to improve theMechanism running stability, raise the accuracy of filling its shoes, simplify the operation, Have no impact to electric network, prolong the component lifetime of the electric system, And prolong the lifetime of the wire rope.

Using the frequency altering and stepless speed regulated motor and single-velocity-ratio spur gear reducer, the mechanism has simple structure, high reliability and easy maintenance. Adopting the technology of big strong drum with LEBUS groove, it is very useful to solve the Knotty problem of abnormal orders when the wire rope is arranged on the drum.

1.1.2 Slewing mechanism
As opposed to other mechanisms, the inertial impact of the slewing mechanism has the most Effect to the crane. The more the jib is long, the more effect is outstanding. It can't solve theKnotty problem with the traditional slewing mechanism, which brings about big torsional Pendulum impact on the crane. After the motor being powered off, the jib runs for a longTime before stopping, lead to difficultly fill its shoes and damage the slewing reducer. The unique technology of frequency altering and stepless speed regulated is adopted inThe routine slewing mechanism of tower cranes. The slewing mechanism starts and stopsSmoothly, fills its shoes fast and correctly.

1.2.3 Trolleying mechanism
The trolleying mechanism, which affects the load filling its shoes, is important mechanism.
Using the technology of frequency altering and stepless speed regulated, the speed of the Trolley changes in the range of 0~100m/min, it is very efficient to reduce the running impact And improve the operating stability and working efficiency in TC7040.
