Surface coating technique

The surface of the entire steel structure is pretreated with shot blast technique by 2 times to remove the traces of rust, meanwhile increase the adhesion and durability of paint.Operation mechanismsBe available for different speed control modes, such as frequency conversion control, tandem resistor speed control, pole-changing control and voltage-variation control and etc. in the aim to meet the needs of the different users.
The hoisting, slewing, trolley mechanisms all feature wide-range speed variation, steady start up and braking, low impact, capable of persistent low-speed operation, precise positioning and easy maintenance.Control systemMajor electric components are sourced from world leading brands with greater stability and reliability.
It is convenient to maintain the tower cranes for the simplicity of electric circuits design and orderly layout inside the electrical cabinet.MastPanel design mast section possesses excellent strength, easy installation, economical maintenance along with convenient transporting. It can save at least 60% of the transportation cost compared with monobloc mast structure.CabinWith great comfort, air-conditioning and humanized design, cabins of our tower cranes provide the operator with optimum view and most enjoyable working environmen

Main Features

1. The tower crane comprises a number of mast sections that are highly interchangeable. The elaborate structure makes it easy for mounting and dismounting.

2. The main support of the mast section has both end faces processed by the jig boring machine to live up to the required flatness of both ends and verticality of the whole mast section, thereby improving the overall performance of the tower crane.

3. The metal parts are jointed by carbon dioxide gas shielded arc welding to achieve a tough and reliable structure.

4. Product quality is further guaranteed by the advanced inspection devices, such as the ultrasonic fault detector and sound level meter.

5. A complete set of safe and reliable hydraulic jacking device is adopted for self-elevating. The tower crane goes up and down steadily and the lifting height varies with the building height. These merits make the lifting equipment ideal for high-rise construction.

6. The cargo boom with triangular cross-section performs with double lifting points. It features excellent rigidity and convenient installation.

7. The hoisting mechanism provides slow dropping of large load in position as well as prompt lifting and dropping for small load. Thus the working efficiency is significantly improved. The lifting speed reducer is purchased from notable manufacturers to ensure that the tower crane works stably with low noise and high reliability.

8. Our self-erecting crane makes use of the single row four-point contact slewing bearing manufactured via advanced process by Hoesch in Germany. This slewing bearing offers fine rigidity as well as excellent bearing ability of axial and radial tilting torque.

9. The slewing device comprises hydraulic coupling and planetary gear reducer, thus it enjoys high torsional capacity, high transmission ratio, compact structure, steady operation, and low failure rate.

10. The speed of the hoisting mechanism and the slewing device can be regulated by the winding wire motor and resistor to smooth the moving process and also prolong the serving time of the tower crane.

11. The components of electrical system are made by well-known enterprises in China and they are stable and reliable in performance.
