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 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.

Shandong Minglong Construction Machinery Co., Ltd, an incorporated company restructured based on former Shandong Zhangqiu Crane Factory, is a professional tower crane manufacturer recognized by the Ministry of Construction. It was one of the first enterprises that achieved Production License issued by the Ministry of Construction in 1988 and one of the enterprises that achieved Special Industry Tower Crane Manufacture License issued by State Bureau of Technical Supervision in 2003. In April 2005 it achieved Special Equipment Manufacturing License of People′s Republic of China and has been certificated ISO 9001: 2000 standard. In 2010, Minglong set up a new trading company-Zibo Chico International Co., Ltd, dealing with kinds of construction machineries and building materials. For more than two decades, we have developed the advanced level QTZ40, QTZ50, QTZ63, QTZ80, QTZ100 QTZ125, QTZ 160, QTZ200, QTZ315, QTZ500 and QTZ2000 self-telescoping, top slewing and trolleying on horizontal jib tower cranes with Changsha Institute of Construction Machinery of the Ministry of Construction.
Besides tower cranes, we also developed construction elevators, passenger elevators, escalators, parking equipment and working platform. Meanwhile, we also offer monitoring systems and devices of tower cranes and building hoists: Anti-collision system, safety protection monitoring system, wind-speed transmitter, overload limiters, load moment limiter, height, radius and slewing limiters, GPRS remote controlling system, space limit monitoring system, anti-overturning monitor controller, wireless floor call system of building hoist, sensors of tower cranes and automatic leveling device system of building hoist.
In the past 30 years, we always adhere to "Science and technology are the primary productivie forces", established "Crane Research Institute", developed education and training of staff, and introduced a group of talents from colleges and universities, gradually optimizing, updating and upgrading products, and leading the industry. Adhering to corporate spirit of "credit by quality, development by innovation, profit by scale, serve customers whole-heartedly", we try our best to meet customers′ demands.
