1. How to select manually liftable lightning rods

Manual lifting lightning rods are also called manual lifting lightning rods and manual lifting lightning rods. Manual lifting lightning rods are used as lightning protection terminals for various equipment such as tents, substations, and gas stations. They are also suitable for use as lightning protection equipment for various special vehicles. 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 manually liftable 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 manually liftable 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 manually liftable 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.
