Product Description
TOPKIT TOWER CRANE 7040-16T
Features of flat top tower cranes
For even higher performance and greater operational options: With its modular jib and without tie bars, the topless crane saves time and money.
The advantages of a modular jib without tie-bars:
Lower overall height(mutiple crane sites)
Easy jib erection and dismantling
Jib configuration can be easily modified as the works proceed, can be erected and or dismantled "in the air", section by section
Never before has there been a crane that is so easy and quick to erect in total safety
Hoisting and trolley ropes installed on the ground, plug-in connections for electrical equipment and safety devices, time-saving factory assembly of cab
Variable frequency slewing, continuously variable speed control by means of a stepless controller, that also adapts to the crane operator's drving style.
Variable frequency hoisting, speed continuously adjusted and optimised according to the load being handled, very slow speeds, smooth speed changes, high productivity.
The masts adopt the standard bases, allowing it to be adjusted to the desired height
The adjustable bases provide a choice of method of installation
-on fixing angles
-on cross-shaped base
-on travelling gear
Or as a climbing crane

Company Introduction:
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. We have set up many marketing offices and agents at home and abroad!
