Product Description Bilding Tower CraneQTZ315(7040-16)Construction tower crane TC70401. Brief introduction of TC70401.1 Working mechanismsThe 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 mechanismThe 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 mechanismAs 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 mechanismThe 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.Hoisting mechanismModel 70RCS40Model of motor YRTE3-180L-4B5PowerKW51.5× 2Hoisting speed2 falls/loadm/min60/430/84 falls/load30/815/16Slewing mechanismModel RCV185BModel of motor YTLEJ132L-185-4B1Torque of motorN. m185× 2Slewing speedr/min0~0.7Trolleying mechanismModel X185KModel of motor YTLEJ132L-185-4B1Trolleying speedm/min40/20/10Jacking speedm/min0.4Outsize of whole craneTip of hoisting jib to slewing center 71.72Tip of balanced jib to slewing center19.2Balanced weightt29Allowed work temperature -20~+40Basic wind pressure under workPa250Basic wind pressure out of workPa1100Power supply50Hz~380V± 10%
