1.How to choose Retractable lightning rod
Retractable lightning rod is a powerful, easy-to-use lightning protection device that uses manual lifting for flexibility and portability.Technical parameters such as maximum lift, closed height, loading form, operation method, and load-bearing weight are the basic requirements for users to choose lifting rods. The design and modification of lifting rods are carried out according to the different needs of customers.
2. Overview of Retractable Lightning Rod
The lifting pole is a carrier for elevated equipment, suitable for vehicle, ship or land. It can quickly, reliably and safely raise communication antennas, lighting, lightning protection, optical transmission and camera equipment to a predetermined height. After the work is completed, the above equipment can also be quickly, reliably and safely lowered to a predetermined height. Our company's manual lifting pole products are made of high-strength aluminum alloy, which are corrosion-resistant, light, large load, low noise, fast lifting, low shock resistance, and stable. It can meet the height and load requirements of different fields and occasions. In addition, our products are also widely used in golf, large football field night lighting, etc.
3. Working Principle of Retractable Lightning Rod
The system adopts screw drive or wire rope drive, has good self-locking performance, can achieve reliable self-locking at any position, and improves safety reliability.
4. Retractable lightning rod installation instructions
Vertical use: The lift can be installed on the ground or on a vehicle. No matter where it is installed, it must be kept vertical to the ground when in use. If the lift is tilted, it will affect the lifting and lowering effect of the lift; if the lift is severely tilted or tilted for a long time, it will also cause damage and danger to the lift.
