Tahan shares 8822/7530 tower crane new eight technical advantages

On July 21, 2017, a new product launch conference for the Tahan Group's 8522/7530 tower crane with the theme of “Ingenuity-Building and Innovation-Leading” was held in Guangzhou. At the meeting, the eight major technical advantages of the new 8522/7530 tower crane were released, as follows:

Tahan Co., Ltd. 8522/7530 Tower Crane New Product Launch Conference and Mid-to-large Tower Crane Product Promotion Conference

1. Adopt CE safety standard of European tower crane, stepless variable frequency control system for lifting and amplitude change; VACON frequency inverter is smaller than YASKAWA Yaskawa inverter used in the past, and the built-in micro PLC of inverter is more advanced. Exactly, MITSUBISHI Mitsubishi PLC programmable controller, contactor and circuit breaker adopt Schneider, more stable performance, smooth tower crane operation, effectively reduce the impact of mechanical operation and reduce the impact on the power grid, improve work efficiency .

European tower crane CE safety standards

2. The company's large-tonnage tower crane is controlled by DC motor. The DC motor has a wide range of speed control, fast response speed, strong overload capacity, large starting and braking torque, and rated torque from zero speed to rated speed. Performance. Traditional tower cranes use RCV and frequency conversion controlled swings, which have slow response speeds, large swing angles, and boom bounces after shutdown. Our company uses the American Parker DC governor to control the rotation, solve these problems, can quickly and smoothly start and stop the rotation, the operation is easier, and greatly improve the tower crane's working efficiency.

Rotary DC motor

Precise positioning

3. The use of four rotary DC motors allows the tower crane to be positioned more precisely and effectively increase the lifting efficiency.

Intelligent double hydraulic caliper device

4.Lifting mechanism adopts intelligent double hydraulic brake caliper device. If the hoisting mechanism gear speed is inconsistent with the speed required by the frequency conversion, the tower crane will stop running, effectively detecting non-human operation and automatic operation and prevention of loss of control leading to the falling of the hook. Tower crane work is safe and reliable.

5. After the installation of the slip ring, no rotation limiter is needed. The tower crane can be rotated freely without worrying about the problem of cable jamming. It is safe and reliable, and greatly improves work efficiency.

7. The use of institutions, electrical boxes, resistors integrated installation, making installation easier and faster.

Rotary cab

8. The reversing cab adopts the original Potain cab, which is spacious, comfortable and beautiful. (This article comes from Dahan shares)
