Main Features

1). With their working radiuses varying from 30m to 80m, QTZ tower cranes are famous for their large operating ranges, varied working methods and wide uses.
2). This series of tower cranes has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism.
3). The tower crane is equipped with all kinds of reliable safety devices, such as hoisting height limiter, slewing range limiter and multifunctional limiter to control the load moment, hoisting capacity and trolley traveling range.
4). Besides, there are also electric safety devices like anemoscopes and obstacle lights and mechanical safety devices to prevent the breaking of trolley axles and wireropes.

TC7031 is top-slewing with novel design, advanced mechanism and reliable performance and can provide you with 4-type: Travelling, attached, stationery and inside-climbing. The crane's max. Working range is 70 m with max hoisting capacity 10t and max load moment 1600KN. M. The max. Height under hook is 200m when the tower crane in stationery max height; Customers can choose change frequency conversion speed change technology on the hoisting, trolleying and slewing mechanism about the tower crane.
Please allow me to introduce the advantages of our tower crane:
1. It is produced by applying the advanced technology.
2. Main material of steel structure adopts high grade Ansteel(Chinese famous steel enterprise) Q345B, and the strength level approach the European Standard Fe510.
3. Electronic control adopt the advanced frequency conversion control technology, RCV/PLC stepless frequency speed electronic control system. Contactors are from French Schneider.
4. All the pins and bolts adopt quenching and tempering heat-treatment technique and surface galvanized process.
5. The pin of mast section adopt sulphocarbonitriding technology and resin heat-treatment technique, which make the pin hard and tough and keep the surface smooth and antirust. Meanwhile, split mast section can save the cost of transportation for customers.
6. Humanized cabin makes the operation safe and comfortable, cabin space with air conditioner.
7. The mechanisms of tower cranes we use are famous brand in China.
