Q:How to explain and classify the types of tower cranes? What do QTZ80 and Q5510 mean?
This is only the tower crane in different periods of different naming:QTZ---- is the general saying in 80s of last century, Q means steel material (usually Q235), T is tower crane (mostly tower top type), Z indicates heightening method is self lifting,PT------ is the naming method in recent years.
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?
First of all, your engineering structure is reinforced concrete Or steel? What's the weight of the lift? The lifting capacity of tower cranes should meet the needs. Generally speaking, steel structure hoisting, tower crane of the largest lifting weight and gravity moment should be large; hanging steel reinforcement of a smaller can.Secondly, the boom length should be covering the scope of construction (can also be arranged to meet several sets of crane lifting coverage). But in the 360 level luffing jib range, can not have obstacles (other cranes and buildings), and the boom and the distance between them (below) should be not less than 2m.Third, in the construction project is relatively high, the site is relatively small, you can mount the internal climbing tower crane. Building covers a large area, sometimes one can solve the problem. Of course, it is more troublesome to disassemble and lift inside, but the standard section used is less and the cost can be lower.
Q:Tower crane railing height is greater than or equal to meters
1500cm underground enclosure shall not be less than 100com. Thank you
Q:What is the calibration value of a tower crane?
Do you mean the calibration value of crane lifting moment? That should be the product of the maximum magnitude of the tower crane and the corresponding maximum lifting load.
Q:How many motors does the ZOOMLION TC6013A-6 tower crane use?
Model: YZRDW225M-4/8 power: 24/24KW speed: 1420/725r/minDirect search {ZOOMLION QTZ80 (tc6013) _ crane Manual Part 1 (Part Two)}, can also be found.
Q:Can the tower crane personnel install the construction elevator?
Although it belongs to the construction of special operations, but the operation of different categories, tower crane demolition workers according to the requirements can not install the elevator!
Q:What does tower crane jacking up mean?
Attached tower crane upper work structure and the lifting sleeve frame connected to the lifting sleeve frame is installed on the lifting jack.
Q:Can the attached arm of the tower crane be welded?
The calculation of the attachment of tower crane mainly includes three parts: attachment rod calculation, connection calculation of attached bearing and calculation of attached frame. (1) the attachment bar calculates the attachment bar and is calculated by the compression member of the pivot shaft hinged at both ends. 1) the internal forces of the attached rod and the internal force of the connecting rod are taken as required by the instruction; if the specification does not specify, or when the spacing between the two supports connected with the building is changed, the calculation shall be carried out.
Q:In order to ensure the stability of tower cranes, generally along the height of the tower and building a number of meters attached
Self lifting tower crane tower 45 meters high to prevail, such as height of over 45 meters, each increased to 10 meters (less than 5 meters, excluding) demolition costs increase 20%, off-site transportation costs increased by 10%.
