FAQ of Tower Crane TC7021

 

Q: What is the principal to quote the right tower crane to the client?

A: First, we need to know clients’ requirements. Normally the following information should be clarified by the client: max lifting capacity, height (height under hook), tip load and jib length.

Second, we need to know what the foundation requirement from the client is. (Fixed/undercarriage/ undercarriage with traveling system), mast section type (panel/integrated), power supply source (voltage, ampere and frequency), the distance between the machine and power supply……

Third if there are special needs, we could suggest proposal according to clear data provided by the clients. End-user, as construction machinery buyer, knows the site situation well and should make decision, such as the machinery specification, type…….

 

Q: What about our tower crane's warranty?

A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.

 

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

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

 

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:More than meters of tower cranes must be equipped with red barrier lights at the top
To see the land of tower crane or floating crane... Basically, however, tower cranes over 30 meters above the tower shall be equipped with red light on the top of the tower and jib.
Q:All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
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:What tower cranes are used on the 30 storey house?
but if the building steel structure more parts or building the number of square meters more than 60 thousand square meters, you need to consider QTZ80 or more of the tower crane, because the type of large lifting capacity is big, the work efficiency is high. Hope to be of help to you!
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:Under what circumstances are winches used and under what circumstances tower cranes are used?
Tower crane hoisting hoist how to brake, driving forklift personnel must undergo professional training, through non emergency situations, can not turn sharp and slam the brakes. 3.3.9 in the chute when running on empty 1)
Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
Q:Climbing process of an internal climbing tower crane
There are two kinds of climbing mechanisms: hydraulic and mechanical. The hydraulic climbing mechanism consists of a ladder ladder, a hydraulic cylinder, a climbing beam and a support leg. The climbing ladder is composed of an upper and a lower bearing beams, separated by two stories, which are fixed on the wall or side beam of the cylindrical structure when the work is used, and both sides of the ladder stand are provided with steps. The load bearing beam corresponds to the four main limbs of the crane tower, and is equipped with 8 guide rollers, which plays a guiding role when climbing.
Q:When the tower crane is installed in the fertilizer tank,
When the tower crane is installed in the fertilizer tank, is the elevation of the upper surface of the tower crane foundation flat with the elevation of the bottom of the new building? Or lower than the trough mark
