QTZ40( 5008)  FAQ

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

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


Q: What is the function of the monitor?

A: Monitor, namely inspection system (like black box), which could store 10000 tower crane operation reports, and it is recommended to be installed in big cranes more than 16t.


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 parameters are lifting machines called large equipment? 200
Said here [] large equipment is a concept that means assessment of whether you did more complete, more complex, (conceptual) large equipment, imagine that you provide [small] equipment detection report may not require? If you can provide a full set of drawings of a mobile phone, it will be recognized, but the mobile phone is never a large [device], the key point, appraisal is the assessment of your ability, to see if you have experienced, or complete certain system equipment manufacturing processThere should be no concept of magnitude, and it's really not a good division of magnitudeAs many job posting said, that is the requirement of [bachelor], college students will be delayed if from yourself, if you have the strength, should be bold to recommend myself, because any recruitment notice can't say: we only recruit college students......
Q:How to explain and classify the types of tower cranes? What do QTZ80 and Q5510 mean?
80 is lifting torque of 800 KN.M, 5510 is 55 meters, big arm of the front crane 1 tons
Q:Tower crane TC6013A-6-A2, what does "A-6-A2" mean later?
QTZ100 in fact, there are two symbols behind T.M, which is used in the country.Q is lifting, T is tower, and Z is self elevating. The 100 is its lifting torque, which means 100 tons. Meters (T.M).
Q:Climbing process of an internal climbing tower crane
The tower is sleeved on the ladder climbing, lifting hydraulic cylinder is articulated in the body of the beam, and the lower end (piston rod end) the middle beam is hinged on the activities. The two sides of the tower are provided with legs, and the two sides of the movable beam are also provided with legs, and the two supporting legs are alternately supported on the ladder steps so as to cause the tower to rise.
Q:What are the four major moving mechanisms of a tower crane?
The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking.There are many types of tower crane, if according to whether the walking mechanism, there is a fixed type and operation type; according to the tower structure is divided into rotary, inferior type, attached itself three; if divided by the amplitude, a trolley type, luffing type and folding arm luffing type three; according to the weight division, with light and medium and heavy three.
Q:Does tower crane belong to special equipment?
Tower crane is a high-altitude operation, the type of work belongs to special types of work, equipment belongs to special equipment.
Q:Can the tower crane personnel install the construction elevator?
First of all, it is certainly impossible to install the elevator, because the tower and elevator certificate is not the same
Q:What is the scope of the installation and disassembly of self lifting tower cranes and the applicable range of the cost and the off-site transportation cost?
The installation and disassembly of the existing self rated tower crane, the first cost and the off-site transportation cost quota are divided by the lifting moment 1000kNm and 2000kNm of the jack up tower crane.
Q:Operation points of tower crane (tower crane)?
Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.
Q:Can the attached arm of the tower crane be welded?
The attached arm of a tower crane can not be welded and can only be bolted.Adhesion calculation of tower craneTower crane attachment (anchor) device structure, internal force and installation requirements in the use of narrative instructions so in the tower crane installation and use, the use of units can be executed according to the requirements, do not need to calculate, only when the tower crane installation position to the building from the over manual provisions, to increase attached rod (Zhi Chenggan) two, spacing or attached rod connected with a building when changing to attached calculation.
