The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q:How much is a team of 40 tower crane
Tower crane rental generally do not rent pricing, can not count number, not today is installed, removed tomorrow!Usually on a monthly basis, with or without use!
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:How often should the crane be inspected regularly?
Tower cranes, elevators, mobile cranes 1 times a year, including rubber tyred container gantry crane every 2 years 1; 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, the crane annual molten metal and hot metal 1.Rules for periodical inspection of lifting machineryArticle 1 These rules are formulated in accordance with the regulations on the supervision of special equipment safety and the regulations on the supervision of crane safety.Article second of the rules from the regular inspection of heavy machinery, is often used in hoisting machinery maintenance unit (hereinafter referred to as the foundation of the self inspection and maintenance), by the State Administration of Quality Supervision Inspection and Quarantine (hereinafter referred to as the State Quality Inspection Administration) special equipment inspection agency approved (hereinafter referred to as the inspection agency) according to the rules, to incorporate the use of registration in the inspection of crane.Article third these rules apply to lifting machinery within the scope stipulated in the regulations on safety supervision of special equipment. All the hoisting machines included in the catalogue of special equipment shall be inspected regularly."No" included in the catalogue of special equipment installation supervision and inspection and the implementation form of hoisting machinery factory, direct delivery unit, for use in pre registration by the local inspection agencies in accordance with the rules of the test items and their contents, requirements and methods for inspection of the equipment before using test (i.e., referred to as the first examination), qualified rear can be used for registration. For the first inspection of hoisting machinery, see Appendix A.
Q:Construction tower crane driver (T) Ben can be used as construction crane driver (S)?
Building crane driver (T); tower crane driverConstruction crane drivers (S); construction elevator drivers; neither is common.
Q:The role of slewing limiter in tower cranes is limited
The function of the rotary limiter is to limit the large arm to a certain set stop. Protect from turning to danger settingThe function of the amplitude limiter is to restrict the car to come out or return somewhere to stop and protect the car from or within certain dangerous range.The hook safety device is to prevent the wire rope from falling out of the big hook, so as to avoid falling and other dangerous events!
Q:How to install the jack up tower crane 30How to install the jack up tower crane?
Since it is self lifting, as the name suggests, it is on its own power that no other crane can rise. It has a special elevated section, a hydraulic device, the upper section rises, the middle empty time section, with his arm to be added to the festival hanging near the artificial it fixed, so that a section of the rising of the. Is to support themselves, and then in the middle plus standard section.
Q:What role does the tower crane torque limiter play?
The torque limiter has two kinds of electronic type and mechanical type, electronic type: can show the torque, radius and load, near the tower crane permit torque, there will be a warning signal, although easy to use, the working conditions of cutting has been greatly affected, but not very reliable, easy to damage, the maintenance of trouble. Mechanical type: Although there is no display and can not alarm, but the work of the letter, the structure is simple, not easy to damage, suitable for construction site conditions.
Q:Tower crane four limit, two insurance, two insurance what is that?
Four limit: torque, ultra high, variable amplitude, walking limit device. Two insurance: hook insurance and reel safety device.
Q:What is the function of the balance valve in the hydraulic jacking system of tower crane?
The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
Q:What is the free height of a tower crane?
General small 40 tower, its free height is about 30 meters. The 63-80 tower is usually about 45 meters. The 125 tower is about 47-50 meters.
