Product Description:

Descriptions of our TC6520(QTZ160) New Second Hand Tower Crane:

1, the topless tower crane reduce the dismounting requirements, lower weight, low mounting height, dismount each mast at a time in the air, save the labor cost, safety and fast.

2, it is suitable for crossover work of the cranes, without the tower cap and pull rod, the safety will be increased when there need the crossover work.

3, It is suitable for the special requirement about the height, such as airport nearby, tunnel, workshop ,and the construction site with high-tension cable.

4, It is suitable for the construction site that has the requirement about the crane boom, it can be used as internal climbing crane in the high-rise buildings, irregular roof or small areas.

5, It is very convenient for dismounting in the restricted construction site, dismount each crane boom at a time by manual.

6, The steel structure of crane boom has long using life and high safety standard.

7, The crane boom is good applicability, high-usage,the design of the topless tower crane boom is easy for realizing the serialization and standardization. Reduce the design and making cost.

8, Low design cost, short cycle, can much better satisfy the multiple demands of the customers.


Advantage of our TC6520(QTZ160) New Second Hand Tower Crane:


1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.

2, The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc.

3, boom stability is good, combination amplitude range.

4, suitable for height have special requirements occasions construction.

5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q:What is the power of a tower crane? Five
TC7525-16D switchboard power 80KWTC5610-4 switchboard power 34KW.TC6015A-10E switchboard power 71.5KWThe other two types have not been touched and will not be answered. I'm sorry
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 kind of equipment must be installed on luffing trolley of horizontal luffing tower crane?
It must be installed:To prevent the trolley cable broken car slip away;The car must have a support wheel to prevent the trolley from hanging in the middle.
Q:Tower crane and construction hoist service life? What are the norms and standards? How to detect?
The tower crane service, QTZ40 state (including 40) the following ten years, more than QTZ63, the age of fifteen years, the construction elevator used for ten years; but specific to various provinces and cities are different, such as Jiangsu Province, the 40 tower crane can be used 8-10 years, QTZ63 tower crane used for 15 years, 8 years of construction hoist. Of course, we should not blindly look at the provisions, tower cranes and the use of strength sometimes determines the life of it!
Q:Tower crane; command; gesture
1. prepare (note): arm extension, placed above the head, five fingers stretched out naturally, palm forward remain motionless.2. main hook: single hand natural fist, in the head, touch the head3. auxiliary hook: a hand clenched, small arm to immobile on the other hand, elbow, hand hand touch before.4. hook up: small arm to the side of the upper extension, five fingers natural extension, higher than the shoulder, with the wrist as the axis rotation.
Q:What are the four major moving mechanisms of a tower crane?
Four big bodies of tower crane: lifting, slewing, luffing and walking.
Q:What is the calibration value of a tower crane?
Three, gravity moment MThe product of amplitude L and the corresponding lifting objects called Q gravity lifting moment, the unit is kN - M.Tower crane capacity is based on lifting moment representation. It uses the product of the maximum working range and the corresponding maximum lifting load as the calibration value of the lifting moment.Four 、 lifting height HIt refers to the vertical distance from the surface to the parking level of the crane sling allows the highest position. The unit is m.Five, work speed1. lifting speed (down) Vn - stable state of motion, the vertical displacement velocity of the rated load. The unit is m/min.2. crane (CART) running speed of Vk, stable state of motion, the running speed of the crane. The operating speed of a crane with rated load on the horizontal (or horizontal rail) surface, at the height of 10m away from the ground, and when the wind speed is less than 3m/s.
Q:What is the difference between lifting height of tower crane and independent height?
It is not the kind of independent highly rigid or flexible attachment function when the tower reached the maximum height, lifting height of the tower is at the maximum height and the minimum amplitude in hook, hook support face datum allows the maximum vertical distance of tower crane.
Q:What are the climbing claws on the tower crane?
Climbing is lifting work cylinder claw pole on the standard main limb rod bearing points of the.
Q:When the tower crane foundation is found, what should be discontinued?
The settlement, inclination and cracking of tower crane foundation can affect the stability of tower crane and should be stopped
