1. How to select telescopic lightning rods

Telescopic lightning rods are also called manual telescopic lightning rods and mobile telescopic lightning rods. Telescopic lightning rods are installed on lifting rods and lifted to a certain height through the mast. They have the ability to receive direct lightning strikes and direct lightning current into the earth to achieve direct lightning strikes. Protective effect. Technical parameters such as maximum lift, closing height, loading form, control 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 telescopic lightning rod

The lifting pole is an elevated equipment carrier, suitable for vehicle, ship or land use. 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 lowered to the predetermined height quickly, reliably and safely. Our company's manual lifting rod products are made of high-strength aluminum alloy, which has the advantages of corrosion resistance, light weight, large load, low noise, fast lifting, low shock resistance, and stability. It can meet the height and load requirements of different fields and occasions. In addition, the company's products are also widely used in night lighting of golf and large football fields.

3. Working principle of telescopic lightning rod

The system adopts screw drive or wire rope drive, which has good self-locking performance and can achieve reliable self-locking at any position, improving safety and reliability.

4. Installation and use instructions for telescopic lightning rods

Vertical use: The lifting rod can be installed on the ground or on a vehicle. No matter where it is installed, make sure the lifting rod remains vertical to the ground when in use. If the lifting rod is tilted, it will affect the lifting and lowering effects of the lifting rod; if the lifting rod is tilted severely or for a long time, it will also cause damage and danger to the lifting rod.
