QTZ50(5008)  FAQ

Q: What is the difference between working wire rope and safety wire rope?

A: There are two kinds of rope using for suspended platform, working wire rope is for working up and down, the other is safety wire rope, just for safe, if the working wire rope broke and fell down, the safety wire rope will locked  immediately. 


Q: Can you equip with light on tower crane jib, monitor, remote control and anemometer?

A: Sure. All of these could be provided with extra cost upon the clients’ requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.


Q: What is 3 main mechanism of the tower crane?

A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.

Q:What measures should be taken to make tower cranes stable?
Increase deadweight and weight.Crane wire rope is phosphate coated steel wire, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope - double coating phosphating, phosphating coating to improve the wear resistance and corrosion resistance of steel wire that is not easy to wear and corrosion resistance is to improve the working life of the plain steel wire rope will be completely eliminated.
Q:What are the characteristics of a tower crane?
Two, according to the structure characteristics of the boom can be divided into the pitching amplitude boom (boom) and trolley jib tower crane (arms).Luffing jib tower crane luffing jib by lifting does not achieve the amplitude, the utility model can give full play to the effective height of the boom, simple mechanism.Trolley jib tower crane is installed on the level of the boom on the track trolley achieve amplitude, the utility model has the advantages of large amplitude range, trolley can near the tower, can load amplitude, the shortcoming is: the boom stress on the structure of complex, high requirements, and the boom and the car must be in the building the upper part of the spire, the installation height should be higher than the roof of buildings 15-20 meters.Three, according to the turret structure, the rotation mode can be divided into lower slewing (turret rotation) and upper slewing (turret not slewing) tower crane.Under the rotary tower crane slewing bearing, balance weight mechanism are arranged on the lower end of the main tower, its advantages are: less bending, low gravity, good stability, convenient installation and maintenance, the disadvantage is the higher requirement to the slewing bearing, installation height is limited.The slewing tower crane is characterized in that the slewing bearing is balanced and the main mechanisms are arranged at the upper end, and the advantage of the utility model is that the lower part of the tower body can be simplified, and the lifting and the adding of the joint can be simplified because the tower body is not turned. The disadvantage is: when the building exceeds the tower height, due to the influence of the balance arm, limit the slewing of the crane, at the same time, the center of gravity is higher, the air pressure increases, the weight increases, so that the total weight of the whole machine increases.
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:What are the luffing, slewing, and walking points of a tower crane?
The luffing of a tower crane is the forearm of a crane;Slewing means the steering mechanism of a crane;Walking means the walking trolley on the luffing range of a crane
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:When the tower crane is installed in the fertilizer tank,
There is no standard in the tower crane foundation and building foundation, there is no such provisions.In fact, you can do whatever you can. The only factor that can be said is the Design Institute, to see if they agree.Design Institute to consider this problem, generally disagree, you let the two based on the surface flat, because there is a stress concentration problems. It's like a pebble under your mattress. So, in general they will demand based on the surface in the construction of tower crane foundation floor, the middle 30-50cm gap with soil pad.Of course, no matter which of these two methods you have to use the back belt to enclose the tower crane foundation.
Q:What kind of tower cranes are available? How about the scope of all kinds of tower cranes?
Tower crane is divided into fixed tower crane, mobile tower crane, jack up tower craneThe mobile tower crane is divided into track type, tire type and automobile typeThe jack up tower crane is divided into two parts: internal climbing type and attached typeUsage: loading and unloading concrete by hanging tank for general construction and installation
Q:What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
It's the same kind of tower crane, but it's only a unit of rated lifting torque. The former unit is 63 tons. M, the latter is 630 kn m. According to the latest national standard "tower crane", GB/T5031-2008 and QTZ63 are written correctly.
Q:Do self lifting tower cranes allow a small swing of the boom in jacking operation?
The upper working structure of the attached tower crane is connected with the jacking sleeve frame, and a jack jack is mounted on the top lifting jacket frame. The upper crossbeam of the jack is connected with the jacking frame, and the lower cross beam is provided with a movable claw, and the lower supporting point can fall on the step of the standard section of the tower body. During lifting, first trim jib and balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.
Q:What are the types of tower cranes?
The tower crane is divided into: fixed tower crane mobile tower crane self lifting tower crane mobile tower crane is divided into: rail type tire type automobile type self lifting tower crane is divided into: attachment type climbing uses: concrete with cage for loading and unloading installation general building mixed
