Product Description:

QTK40 SELF ERECTION TOWER CRANE

 

1.1 Brief introduction

The QTK40 model self erection tower crane is developed by our company on basis of years of experiences in production and new technical innovation.This tower crane is whole consignment & fast set-up vertical and level transport machinery. Mainly apply to 7~10 storey civil buildings. This machine also could used in factory, goods yard, station, ports to move products, as well as to be a mobile hoisting machine.

 

1.2 Features

The famous feature of this kind tower crane could realize fast-installation and whole consignment transportation. After whole enfolding of tower crane, two workers could transport tower crane by one truck crane (8ton), and the installation could be finished within 40 minutes.

Other features:

(1) Inner tower expansion in suit place, it could auto-lock and release

(2)  lifting beam could auto-unfold or fold when towers stretch and unfold

(3) (Tower stretch and unfold, beam unfold, counter weight load ,which all could do range form 0~360°

(4) Adopt drum, whole steel wire rope pulley system, to realize lifting& installation set-up work

(5) Have two kinds interchange device: track and fixed supporting lug, to adjust different uses

(6) The angle of altitude of lifting beam is 15, then could increase the height of lift, but its Max lift weight is 1100kg .

(7) Lifting mechanism, trolleying mechanism and traveling mechanism adopt frequency & gear changable to control speed.

(8) Slewing gear adopt electric resistance control mode, smooth starting, with good positioning performance

Q:Method for operating tower crane
2.21, drivers must pass the escalator up and down, up and down the escalator, hand tools are prohibited items.2.22 do not drop any objects from tower cranes or defecate.2.23 winter in tower crane operating room heating, should be taken to prevent electric shock and fire measures.2.24 any tower crane with an elevator must comply with the instructions in the elevator manual. No overloading or violation of the operating procedures.2.25 multi machine operation, should avoid two or more than two tower cranes overlap in the radius of rotation. Special circumstances, need to overlap operations, must be safe distance between the vertical arm to ensure the safe distance and the lifting of materials, and have reliable safety measures approved by the competent technical leadership before construction.2.26 jib cranes in heavy lifting off the ground after lifting, rotating and walking three actions can be done at the same time, but the amplitude only alone, strictly with variable load. A crane that allows variable amplitude loading shall not vary at full load or near full load.2.27 lifting hoist is not installed in the rotating part of the crane, lifting operations may not continue in one direction continuous rotation.2.28 a crane with a mechanical torque limiter must adjust the tonnage indicator of the overload limit device according to the radius of gyration and the rated load at that radius.2.29 bend rail subgrade must comply with the provisions of the crane should turn on the outer rail surface of the sand, rail, rail and wings painted with grease. The counterweight box shall be turned to the direction of the outward turn. It is strictly prohibited to do lifting or turning on heavy roads.
Q:Tower crane 4 how to change the rate of 2 magnification, how to change, say detailed points
There is a magnification pin on the hook group. When the magnification pin is removed, the pulley will automatically slide to the lifting trolley.
Q:How do tower cranes rise?
The weight and concrete foundation shall be made in advance and marked, and the ground ground endurance shall be no less than 20T per square meter. The chassis and standard sections are then assembled on this basis. The standard section of tower crane is the main part of the main part of tower crane. It is also the main role of heightening the height of tower crane". In the construction process, tower crane accompanied by the rise of buildings, naturally need to heighten. When the tower is hoisted, the upper frame is raised upwards with the jack up, so that there is a space between the tower body and the frame, and the standard section of the tower body is installed in the space. In this way, the purpose of the tower crane is realized.
Q:Which kind is better, gantry crane or tower crane?
Each has advantages, the use of different conditions, the use of different cranes, tower cranes can not move, but the lifting height can be very high, the door machine has tracks can be vertical and horizontal movements, lifting height, tower crane is not high.
Q:Which is the main basis for the disassembly and assembly process planning of tower cranes?
Before the installation and disassembly of 2.0.10 tower cranes, special construction plans shall be worked out to guide operators to perform installation and disassembly operations. The special construction plan shall be prepared according to the actual conditions of the product specifications and the working site of the tower crane, and shall comply with the requirements of the relevant laws, regulations and standards. The special construction plan shall be examined and approved by the technical, safety and equipment departments of the unit, and approved by the technical person in charge, and shall be approved by the supervision unit.2
Q:Tower crane 10-5-20 is 6T, and 10-5-21 is 8T. What do you mean by tons?
6T/8T refers to the maximum lifting capacity of a tower crane. It doesn't matter what 10-5-20 has to do with it. Maybe your list of numbers is serial number.
Q:What is the difference between a crane and a crane in a tower crane?
Informal: hoisting signal worker: refers to the signal flag!Cable man: rope!
Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
Lifting weight limiter: limit maximum lifting weight;Torque limiter: limit the maximum lifting torque;Height limiter: limits the maximum and minimum position of the hook lifting and lowering;Amplitude limiter: limit the lifting trolley in the boom on the outside, the inside position;Slewing limiter: limit of up to the number of rotating ring arm;
Q:What is the free height of a tower crane?
The free height of tower crane is different according to the size of tower crane.
Q:When building tall buildings, where is the bottom of the tower crane installed?
A firm foundation is built before the tower crane is used, and then the crane is fixed to the foundation
