The main technical feature as follows:
1. This product combined the controller and thyristor module, the connection of the users is simple and easy. This is to prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
2. Realize the best optimization of AC voltage control curve and DC voltage control curve.
3. With the function of inching during operation, realize the accuracy.
4. The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
5. Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.

How to ensure the safety and reliability of laying the roadbed and track of the tower
In this article,there will explain how to ensure the safety and reliability of the tower crane roadbed and track laying, the selection of pillow materials, construction, and the setting of the limit position blocker.
1. The laying of the roadbed and track of a tower must be carried out in strict accordance with the provisions of its specifications. In general, the subgrade soil carrying capacity: medium-sized tower(3 ~ 15 T) 0.12 ~ 0.16 MPa; Heavy tower(above 15t) 0.2 MPa. And should be repaired flat compaction, on the sand, ballast, and drainage measures.
2. Pillow wood materials can use wood, reinforced concrete or steel sleepers. The cross-sectional dimensions are specified in the specifications(such as 16 × 240, 180 × 260, etc.). The length of the sleepers should be at least 1200 mm larger than the gauge size.

When using a long pair of short sleepers, a groove steel rod should be added every 6 m to ensure the gauge. Pillow spacing is 600mm. When using a stereotyped base box, it should be checked and confirmed to meet the requirements before use.
3. Both sides of the track shall be nailed to each pillow with a path(or pressed with a pressure plate), and shall not be missing or loose.

The joint of the track should be staggered, the joint should be mounted on the pillow, the height difference between the two ends should not be more than 2mm, the splint of the joint should be matched with the track and the bolts should be fully filled and secured.
4. Orbital horizontal deviation is not more than 1/1000 in aspect direction. (The level instrument should be used. In the two tracks, within 10 M, the three points of Yuyu can not be measured separately.
5. At 1M from the orbital terminal, an extreme position damper(stop) should be set and its height should be greater than the radius of the running wheel to stop the tower crane from sliding after power failure.
6. The basic construction of the fixed tower crane should be carried out according to the design drawings. The detailed design calculation and construction plan should be included in one of the special construction organization design contents of the tower crane. After construction, it should be experienced and recorded.

It is very necessary to correctly grasp the function of the tower attached wall device and clamping clamp
The free height of the lifting tower should be determined according to the requirements of the manual. When the height of the lifting tower exceeds the specified value, it should be attached to the building to ensure the stability of the lifting tower. The blind elevation of the tower crane will cause the collapse of the tower crane. Therefore, it is very necessary to correctly grasp the function of the tower attached wall device and clamping clamp.
Walls attached:

(1) The strength of the force attached to the building must meet the design requirements.
(2) When attaching, apply theodolite to check the vertical degree of the tower and make adjustments. The arrangement of the poles for each attached wall device, the spacing between them, and the vertical distance of the attached wall device shall be in accordance with the specifications.
(3) When the length and angle of the attachment rod need to be changed due to the particularity of the project, the strength, stiffness and stability of the attachment device shall be checked to ensure that it is not lower than the safety degree of the original design.
(4) When rail lifting is used for attachment, it must increase the bearing capacity of the orbital foundation and cut off the power supply of the walking mechanism.

When rail crane is used in the open air, anti-wind clamp rail pliers should be installed. The clamping clamp device must ensure the braking effect after the clamping. When the driver needs to leave the tower crane for lunch, work and temporary parking, the clamping clamp of the tower crane must be clamped in accordance with regulations before leaving.
