Product Description

Qtz315 (TCT7530-20) Topless Construction Building Tower Crane



Brief introduction
Flattop tower cranes are generally used on construction sites or bridge construction sites. The position of the hooks can be controlled by the boom swing and the distance of the trolley, and the objects can be lifted at the turning radius. Compared with the tower crane with tower head and tie rod, the mechanical model of the boom is simple and clear. Because there is no tower head, the installation height is low, making installation quicker and safer. Suitable for large building needs.

The flattop tower crane is a new type of tower crane developed in recent years. It is characterized in that the tower tip and its front and rear tie rods are eliminated from the structure of the original jack-up tower crane, and the structural strength of the big arm and balance arm is enhanced. The big arm and the balance arm are directly connected, and the advantages are as follows:
1.The whole machine is small in size, convenient and safe to install, and reduces transportation and storage costs; 
2.The boom has good tolerance, uniform force and small damage to the structure and connecting parts;
3.component design can be standardized, modular, interchangeable, reduce equipment idle, improve investment efficiency.

Feature of tower crane
1.Suitable for all kinds of construction project and can work under all kinds of work condition.
 2.It has high working speed, good speed-adjusting performance, steady operation and high  efficiency.
 3.The crane has complete set of safety devices, which can guarantee the safe and high efficient  operation of the equipment.
 4.Three-speed motor and mono-speed ratio decelerator are applied in the lifting structure, which  enables heavy load low speed and light load high speed.
 5.Planet gear decelerator is applied in the circumcise rating structure, together with moment-limiting  hydraulic couple, which can realize high load capacity, steady starting and reliable operation. 

Advantage of Tower Crane
1.Robot automatic welding system;
2.Automatic impeller blasting and spraying assembly line;
3.CNC plasma cutting machine;
4.Precision machine tools;
5. France Schneider contactor;
6.Jiangte motor;
7.Equipped with complete set of safety devices

Safety features
Full set of safety protection equipment:weight limit,moment limit,height limit, and slewing limit,emergency brake, labor protective devices like rest platform and guardrail.
1.Weight limit: If the material is over the capacity, the crane will give a sharp warning for   protection itself.
2.Moment limiter:Real-time monitoring and detection of crane working conditions, with its own diagnostic function, rapid dangerous status alarm and safety control.
3.Height limit:Control the lowest and highest extreme position of lifting hook.
4.Slewing limit: Control the extreme turns number of turn left and right.
5.Emergency brake: If the operation staff  encounter some emergency situation, we could start the emergency brake system to protection the related treasure.

Control mechanism
Hoisting mechanism is driven by three-speed electromotor with high working speed and good speed-adjusting capability and high efficiency; Derrick mechanism using worm-wheel reducer can meet operating needs. Slewing mechanism that is driven by two-speed electromotor; Make operation more stable and reliable.
