FAQ about Tower Crane

 

Q: What kinds of tower crane are available now? 

A: Four main categories: normal  tower crane  with cat head, internal climbing  tower crane , top less  tower crane  and luffing  tower crane.  

 

Q: What kind of steel used for  tower crane ?

A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.

 

Q: What about our  tower crane  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:When the tower crane top height is more than meters
Circular of the Ministry of housing, urban and rural construction on Issuing the measures for the safety administration of sub hazardous and sub divisional projectsAnnex No. [2009]87 [Annex two]"More than a certain size of the risk of larger sub sub project scope."
Q:Are there any special requirements for the installation of wall fittings of tower cranes?
The spacing along the height of the retaining wall piece must comply with the installation instructions for the tower crane;
Q:Why are there extra placards attached to the tower crane tower?
1. additional placards can sometimes damage tower structures and cause damage to the tower during installation. There is a security risk;
Q:The role of slewing limiter in tower cranes is limited
All kinds of electrical equipment protection limit device and limit position and cap mechanical limit, overload protector.The most important is the anti drop protector!
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
How to choose tower crane in engineering: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:What is the difference between crawler crane and tower crane?
There are many differencesThe crawler is used to transport items in a smaller range of motion (site)A tower, used for construction, stationary, or maneuvering along a railroad track.Crawler can easily reach the magnitude of 50 tons or moreMore than ten tons of tower are relatively commonTrack internal combustion engine, hydraulicTower type general power consumptionWait, wait......
Q:The special equipment specified by the state is a periodical inspection cycle, wherein the crane is carried out every many years
(two) small light lifting equipment, bridge crane, gantry crane, gantry crane, cable crane, crane mast, railway crane, jib crane, mechanical parking equipment every 2 years 1 times, the crane annual molten metal and hot metal 1.The rated load test, static load test and dynamic load test shall be carried out in the first test and the first periodic inspection, and the rated load test shall be carried out 1 times after each of the 1 inspection periods.The inspection process, the existence of major risks of hoisting machinery (such as special work environment, frequent accidents, etc.), inspection agencies approved by the provincial quality technical supervision department agree, can be appropriate to shorten the regular inspection period, but the short period of not less than 6 months.
Q:Calculate the tower crane gantry crane
It's a gantry crane, not a tower crane
Q:What does "jack up" tower crane 1000KNm mean?
The Greek letter of torque is tau. The concept of torque originates from Archimedes's study of leverage. Rotational torque, also known as torque or torque. The torque can change the rotational motion of an object. Pushing or pulling involves force, while torsion involves torque. The moment is equal to the cross product of the radial vector and the force.
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
