Overviews On Some Telescopic Lifting Antennae Masts Of Typical Structures

Antenna lifting mast is a component of radar and communication equipment, so the choice of antenna lifting mast depends on the use of the whole equipment, the conditions of use, performance requirements and characteristics of the antenna lifting mast itself. This paper describes the characteristics and uses of some typical masts which are widely used in all over the world.

Single Screw Lock Hook Structure Mast

Single screw hook structure mast is generally made of aluminum alloy tube as the main material. The second tube is driven to rise by the screw female, and the other tubes are connected by hook. After the electric machine is energized, the mast can automatically rise and fall section by section. The mast of this structure has small bearing capacity, light self-weight and high horizontal Angle accuracy. It is suitable for carrying small weight and small volume microwave antenna. It is installed on the side wall of vehicle-mounted square cabin to avoid serious eccentricity of car body.

Wire Strander Wire Rope Structure Mast

Wire strander Wire rope structure the wire strander on the mast is a winding drum with self-locking function. With the winding drum winding clockwise or counterclockwise, the pulling force of the wire rope drives the mast to rise and fall simultaneously. Most of the parts of the mast are made of thin-walled aluminum tube, and its self-weight is smaller than that of other kinds of metal masts. Its disadvantages are small bearing capacity and low horizontal Angle accuracy, so it is suitable for installing omnidirectional antennas with small weight and volume.

The Multi-Screw Structure Lifts And Lowers The Mast Section By Section

The multi-screw structure lifts the mast section by section, driven by the screw female screw pair on each section of the pipe (excluding the outer leather pipe). All lead screws are self-locking, bearing capacity, strong wind resistance, safe and reliable. Suitable for carrying weight is less than 300 kilograms, erection height is less than 18 meters of antenna, this structure mast is also used more widely in the country products

Multi - Screw Structure Synchronous Lifting Mast

Multi - screw structure synchronous lifting mast and multi - screw structure section by section of the mast similar characteristics. In addition, because all the pipes (excluding the outer pipe) with the same step of lifting also has the characteristics of fast speed and large power consumption.

Single Screw Wire Rope Structure Lodging Mast

Single lead screw steel wire rope structure inverted mast using square steel pipe as the main material, through the screw screw female screw pair drive the next number of second pipe rise, the rest of the pipe are by wire rope pull up at the same time. This structure mast has the lodging function. In the process of transportation, the mast is in a horizontal state, which reduces the height of the overall center of gravity of the vehicular square cabin to avoid excessive transportation and ensure smooth running. When the mast is working, the pitching lever holds the mast upright.

Single lead screw steel wire rope structure lodging mast has high strength, stiffness and wind resistance, the highest erection height can reach 40 meters, suitable for bearing large weight, large volume antenna high-end erection and withdrawal tasks.

Carbon Fiber Roof Mast

The structure of the mast pipe is made of carbon fiber material, and the insertion connection between the pipe and the pipe is used to achieve the lifting of the roof. It has the advantages of simple structure, light weight, convenient erection and removal, and can be loaded into the backpack after disassembly, improving the mobility of transportation, and is suitable for field work.

Some radars and communications equipment are not fixed in one place, but move frequently, and may be used in high mountains that are not convenient for driving. The antennas of these equipment should often be set up, removed and transported, because this must require the antenna lifting mast to be set up and removed easily, and do not need another lifting equipment that can lift the antenna mast to the higher altitude of the mountain. At this time, radar and communication equipment usually use carbon fiber tube ejector structure antenna to lift the mast.
