As a result, the one-time qualification rate of the products is improved and the company is able to win continuous trust from customers。

1.    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. 
4. It adopts standard sections (for models of over 12t) of piece assembly structure, split structure stock, and assembled platform, which meet the transport requirements for standard container.
5. The extra-long boom is designed with a rope-supporting trolley, and the speed of which is 1/2 of that of the luffing trolley, which can achieve the most optimum rope-supporting effect. The structure has applied for national patent.
6. The lifting mechanism adopts speed regulation by frequency control or by eddy current brake series resistance, featuring good lifting performance; The slewing system adopts frequency control by torque electric motor or by coil winding type electric motor with hydraulic coupler, featuring smooth operation and small slewing impact.
7. All kinds of safety devices are reliable and easy to adjust; both the safety monitoring control system and traditional safety system are available, the double system ensures safety operation of the tower crane; the hydraulic system adopts low/medium pressure design, featuring higher safety and reliability.

The construction hoist product  produced has achieved internationally advanced level in terms of industrial design, control and the drive performance, as well as the operation safety and comfortableness. And is also making efforts to keep improving the product, as what the construction hoist lifts is not only people and material, but also a kind of social responsibility and service concept…
The new generation SC series of construction hoists adopt modular structure, ergonomic design and advanced manufacturing technology, thus the adaptability and reliability of the product is greatly improved, e.g. the max. lifting height can reach 300 meters. The product adopts multiple patented technologies, reaches advanced level in China, and the market share in domestic market is increasing year by year. The product has also been exported to overseas countries like Russia, Turkmenstan, Vietnam, etc. winning the confidence of customers of both home and abroad

1. The cage drive system is equipped with buffering device, so the cage moves more stable.
2. The ergonomically designed cage interior improves comfortableness.
3. The unique structural design has applied for patent.
4. The typical technologies ensure the malposition difference of the guide rail.
5. The excellent parts in the industry ensures reliable quality of the machine.
6. Precise assembly and accurate drive.
7. Professional solutions for special projects.
8. The complete safety devices ensures reliable control system.

Q:When the tower crane top height is more than meters
Three, lifting and installation, demolition works(1) lifting projects with unconventional lifting equipment and methods with single lifting weights of 100kN and above.
Q:Tower crane installation, wind speed is greater than 12m/s, wind should stop operation,
This is not on the project department climbed to tower crane to measure wind speed, regardless of height, is listening to the local meteorological station forecast, more than five winds, should stop working.
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:How much should the verticality of a tower crane be controlled? Thank you
No, the wind speed is not more than 3m/s, the independent state tower (or attached state highest attachment point above the tower axis) lateral verticality tolerance is 4/1000, the highest tower axis perpendicularity allowed attachment line below the point of difference is 2/1000.
Q:The earthing resistance of tower crane shall not be greater than that of the tower crane
Three. Technical specification for temporary power safety on construction site JGJ 46-20055.4.2 within the construction site crane, derrick and Longmen machinery equipment, metal structure and steel scaffolding and under construction in construction projects, when lightning protection devices in adjacent buildings, structures and other facilities outside the protect zone of lightning arrester, lightning protection device should be installed in accordance with the provisions of.5.4.7 lightning protection electrical equipment machinery, connected to the PE line must repeat grounding at the same time, with a repeat of the mechanical and electrical equipment grounding and lightning protection grounding machines can share the same grounding body, but should be consistent with the repeated grounding resistance of grounding resistance requirements.The electrical equipment of 9.2.1 tower crane shall comply with the requirements of the current national standard "safety regulations for tower cranes" GB5144.9.2.2 tower cranes shall be subjected to repeated earthing and lightning protection grounding as specified in Clause 5.4.7 of this code. The earthing device of the track type tower crane shall comply with the following requirements:L the two ends of the rail are respectively provided with a grounding device;The joint of the 2 track is electrically connected, and the ends of the two tracks are electrically connected in the loop;3 long track every is not more than 30m and a grounding device.
Q:Tower cranes should stop working when the wind speed is greater than the magnitude.
Rules for safety regulation of tower crane,The installation of tower crane is strictly prohibited at grade 4 or above
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 is the brand of ZOOMLION tower crane?
This is not very good answer, the United States originally used Tianshui 213, and then used the Japanese MITSUBISHI, used Schneider, LG, star power, Eaton.How big is the lift? It depends on the size of the motor you use. 24KW motor, the choice is about 100A. 30KW uses 125-150A, 55KW, and 150-180A;Generally 40A contactor is used for turningCar selection of 25A on it.
Q:What are the main parameters of a tower crane?
For car luffing tower cranes, the maximum lifting height is only related to the height of the tower, and when the height of the tower is determined, the maximum height of the ceiling is a certain value.In addition to the 4 major performance parameters. And the working speed (including lifting speed, rotary speed and walking speed of car, traction speed), an important parameter gauge, wheelbase, total power, motor structure weight, balance and gross weight, etc.. These important parameters often determine the tower crane selection, such as speed of operation often determines the number of selected cranes, motor power requirements of power supply load, gauge, wheelbase of the site, and the structure weight, balance weight, weight of the foundation treatment of heavy machine requirement.Tower crane (tower crane) is called tower crane, also known as tower crane. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. The tower crane consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..
Q:What is the difference between a tower crane and a jack up tower crane?
The jack up tower crane is a tower crane (that is an internal climbing tower crane) that is added and reduced by its own special device, namely, the standard section of the tower (that is, the attached tower crane) or the whole climbing tower itself.
