9、stallation and operation, please working as the specification book3. For make sure the performance of the machine, please use the spare parts from our compnay4. If malfunction of our machine, please contact us5. All spare parts of rotate, no touch, its include rope guide, Stop device, coiling block,

10、 steel wire rope6. In the course of assemble disassembly, if the spare parts broken, its must be choose the same type and same strength spare parts to exchange.Four. working principle The rotate of this series three-speed motor of hoisting mechanism, through reducer deceleration and drive the coilin

11、g block. The hoisting mechanism include 3 Lifting speed and 3 rate of descent. medium speed hoisting when raising , it will electrify of the motor stator low speed coil. After change to high speed coil, raising with high speed. When decline, its need working with same start sequence.When stop workin

12、g, electrical control part need change to low velocity with automatic, its need slow down before stop working, make sure braking balanceThe working file of raising system include medium speed gear and high speed gear. The low speed gear use for starting and , general can not working with long time.F

13、ive. installation debuggingBefore installation, its need check if looseof the connect bolt of motor, reducer, braking, stroke limiter, bearing pedestal etc. If loose, please tightened and installation in the tower craneBefore installation, please compare the installation drawing dimension, Fix it in

14、 the tower crane balance arm with pin roll with 4 - 40.5 (h9). When connect the Hoisting mechanism and balance armWhen installation the machine, please reference the installation drawing dimension, use pin roll with 4-40.5 (h9), take the mechanism fix in the balance arm. When connect the raising mec

15、hanism and balance arm, please make sure the otic placode working with natural, not allowed compel connect, avoid transformation of the mechanism chassis and result in badness working. After place the machine, every cotter of the pin roll need open with sufficient, avoid fetch way. Before installati

16、on, its need use the wedge in the one end of the raising steelwirerope fix in the plate block ektexine of the coiling block. After use about 1/10 single rope traction rating to cocking steelwirerope. The motor through reducer transmission coiling block, and make the steelwirerope twine in the coilin

17、g block layer-by-layer. The safe numberofturns not less than 3 of steelwirerope winding in the coiling block. The safety factorsteelwirerope not less than 5.5. If not use leg along device, for smoothly several layer twine in the coiling block of the steelwirerope, we suggest the steelwirerope depart

18、ure the angle of barrelarbor vertical plane. And its better less than 1.5warning: strictly prohibit add the lubrication oil not according the stipulateWarning: strictly prohibit put the hand into the rotary part of the machine. Six maintain Before working, please add GL-5 heavy loading hyperbola gea

19、r oil of the reducer ( 85W/95) to oil pointerIts need check the bolt if loose after working 50 hours, If loose, its need firm in time.After, change the oil every half year. Later, check the oil level every day and add oil as the rule.Before installation and every one month, its need check the adjust

20、 the braking as the braking specificationThere is a lubrication glib outside of end of coiling block bearing foundation , its already fill 2 before leave factory lubrication grease.Its need often check the the spare part of firm, if loose, its need firm it. Its need often check the mechanism if oil

21、leak. If oil leak, please maintain in time. And check the reducer lubrication oil level in key point, add lubrication oil in time, keep the right oil level.When check working, if appear noise and fever, its need stop working and check it. Constraint maintain content and period as the follow form:Mai
