Lifting poles, lifters, telescopic masts, lifting tower masts, and lifting brackets have the advantages of large load, low noise, fast lifting, low shock resistance, strong self-fall buffering performance, and stability. The company's lifting rods, lifters, lifts, lifting platforms, and lifting brackets are made of high-strength aluminum alloys, which are light in weight and can meet the needs of height and load in different fields and occasions. In various natural disasters, emergencies It plays an important role in rescue and rescue at night.
2. Technical indicators
1) Electric telescoping antenna mast Collection height: customized according to customer requirements
2) The total height of electric telescoping antenna mast: customized according to customer requirements
3) Electric telescoping antenna mast installation method: customized according to customer requirements
4) Material: High-strength aluminum alloy profiles are used, which are highly resistant to corrosion; the inner wall of the cylinder is sealed and connected by high-pressure wear-resistant porcelain treatment.
5) Pressure-holding performance: high-level sealing performance, the 24-hour lift mast slides less than 10mm in a static state. The piston swing stroke stroke structure is adopted, and the heavy piston is made of high-strength graphite-containing materials; all transmission systems are closed, and there is a rubber sealing ring between the rod body and the rod body for sealing (this sealing ring is a seal imported from Japan NOK ), good waterproof and sand-proof performance, strong anti-corrosion ability;
6) Surface treatment: hard oxidation increases the strength of aluminum alloy profiles;
7)Manual Mechanical telecopic Mast wind resistance: our rod body adopts circular section, in the same installation space, the circular section can provide higher strength, rigidity, torsion resistance and bending resistance; wind resistance level 8; With anti-rotation function., working pressure: <0.30 Mpa;.
8) Manual Mechanical telecopic Mast has a structure with built-in wires: our company first realized that the equipment control wires and power wires are fixed inside the lifting rod, and the first domestic wiring of the lifting rod is realized, which is further in terms of appearance and performance.
9) The vehicle lift mast is fixed on the roof of the vehicle, or installed around the vehicle, and fixed by the combination of the trailer and the support frame. When the customer equipment is selected, the original height of the vehicle-mounted lifting mast should be determined according to the height of different types of installation surfaces to the top. As a result, when the product is installed on the top, its original height is the shortest, so as to ensure the maximum height passability of the car body and minimize the wind resistance of the equipment.
3. Use technical instructions
1) Knowledge about Manual Mechanical telecopic Mast
The wind resistance performance of the mast is one of the important technical indicators of mast products. Every customer wants to know how much wind their mast can withstand with the load installed, but at present, almost no one can answer this question accurately. This is because the wind resistance of a mast is determined by three factors:
A. The material and structure of the mast
B. The height of the mast
C. Weight, volume and shape of the load
In the case where the above three conditions are clear, to obtain the index of the specific wind resistance performance of the lifting mast, lifter, telescopic mast, lifting tower mast, and lifting bracket, the following three methods can be used:
1) Theoretical calculation is to use methods such as finite element analysis.
2) The simulation experiment converts different levels of wind into wind pressure, and then uses physical methods (tensile force meter) to test.
3) Wind tunnel experiment The mast and the load are placed in the wind tunnel to simulate the wind speed for testing.
In addition, the company's electric telescoping antenna mast, Manual Mechanical telecopic Mast products are also widely used in golf, large football field night lighting and so on.
