Product Features
Pneumatic lift rod has the advantages of large load, low noise, fast lifting, small shock resistance, strong self-falling buffer performance, stability, etc.
When selecting lift rod for customer equipment, the original height, maximum lifting height and maximum load of the lifting mast shall be determined according to the height of different types of mounting surfaces to the top. It is convenient for the company to carry out personalized customization according to customers' needs and cater to customers' solutions;
Lift rod when the product is installed on the top, its original height is the shortest, ensuring the maximum height of the car body and minimizing the wind resistance of the equipment.
The lifting mast can be customized according to customer requirements, and can achieve a height of 1-35 meters and a maximum load of 350 kilograms.

Process Flow
Made of high-strength aluminum alloy, light weight, to meet the needs of different fields and different occasions for height and load
Lift Rod adopts high-strength 6063 aluminum alloy profile, and the surface is treated with anode hardening, which has high hardness, film thickness, wear resistance and corrosion resistance.
In addition, our company first realized the built-in pneumatic lifting rod internal power cord, which is a leading technology in China and further improves the appearance and performance.

Application prospect
With the rapid development of science and technology, pneumatic technology is bound to get rapid development. With the increasing degree of automation in industrial production, the requirements for reliability and accuracy of automatic control system are also constantly improving, which promotes the innovation and development of pneumatic technology. At the 2012 Hannover PTC-CeMAT exhibition, pneumatic technology experts from all over the world agreed: "The Development Trend of pneumatic technology is to integrate multiple disciplines and theories, such as sensor technology, communication and information processing technology, piezoelectric Technology, fluid mechanics theory, mechanical and electronic disciplines and other technical means in many fields are integrated into a comprehensive automatic control technology integrating various disciplines through the idea of overall electromechanical integration, provide a complete set of automation solutions for the target project." Pneumatic technology is upgrading and changing.
Different from the key development direction of pneumatic technology with standardization, modularization, integration, miniaturization of Pneumatic Components and service life of extender pieces at the end of the 20th century, nowadays, energy conservation and gas use in pneumatic systems, electromechanical integration of electric drive combination has become a new development trend of pneumatic technology. In addition, more and more attention has been paid to systematization and emphasis on diagnosis/monitoring functions. These development trends of pneumatic technology will continue for a long time in the future. Pneumatic technology has moved towards the overall solution of industrial automation.

Technical Instructions
Bolt self-locking is based on the model structure characteristics of the mast cylinder, using the shear force between the full-length external key of the outer wall of the cylinder and the spring pin on the joint sleeve to carry out mechanical positioning on each section of the mast. The positioning effect depends on the material and cross-sectional area of the key. Because the material of the mast cylinder is aluminum alloy and the cross-sectional area of the key is very small, this latch self-locking device is only suitable for small and medium-sized mast with light load.
Direct pull self-locking is generally applicable to masts whose initial height is below 1.6m, while suspended self-locking is applicable to masts whose initial height is above 1.6m.
Brake self-locking is to achieve braking effect through friction between brake and lift rod, which is equivalent to wheel and brake device. When using the lock self-locking mast, it is necessary to tighten the lock. The size of the required braking force depends on the size of the load. The tighter the rotation, the greater the braking force. In actual operation, it is clear whether the braking force meets the load requirements by using a torque wrench. Wrenches or torque wrenches are selected accessories, and the calculation method of brake self-locking braking force is to adopt the thread tightening torque formula.
For tightening torque value, Nm
F bolts bear the best clamping force, N;
d thread diameter, mm;P is thread pitch, mm
The integrated brake and separate brake can achieve the same braking effect, and the difference lies in whether the design can meet the requirements of the initial height, maximum elevation and load of the mast. Under the same conditions, the initial height of the separated brake mast can be lower or higher.

Our company pressure pattern lift rod advantages:
1. Low failure rate
The mast is made of national grade aluminum alloy 6061, 6063 and stainless steel, driven by air pressure, with cylinder inside, simple structure, far lower failure rate than other driving methods, and easy to use and maintain. However, other internal structures are complex, which easily leads to wire rope winding phenomenon. After rising up, it is difficult to drop down.
2. Light weight
Internal reduction of gear, steel wire and other accessories, using air pressure as power, does not increase the weight of self-weight. For example, the 6-meter electric lift rod weighs 80kg, while the 6-meter pneumatic lifting rod is only 30kg, thus greatly reducing the damage to the vehicle chassis by lift rod.
3. Good sealing, dustproof and sand-proof
Pressure pattern lift Rod Mast has high sealing requirements, so the sealing is done well and can be effectively reduced. Sand, gravel, etc. enter Rod body and scratch Rod body of the surface.
4. Anti-rotation
Each section is connected by feather key, which can prevent rotation at any height.
5. Small wind swing
Because the pneumatic Rod adopts a high sealing density of guard circle, the mechanical gap between the joint and the joint is very small. When the rod body is raised, the stability is high and it is not easy to shake. At present, our company can realize the deflection ≤ ± 30mm. While other rods have smaller deflection ≤ ± 200mm
6. Strong environmental adaptability
The mast is made of aluminum alloy, stainless steel and other materials. The surface is treated with anode hardening, which is anti-corrosion and anti-rust. It is not afraid of salt water, flooding and ultraviolet rays. Pneumatic lifting rod operating temperature range:-55 ℃ to 80 ℃. While the electric lift rod is only-50 ℃ to 70 ℃
7. Heavy load
Pressure pattern lift rod larger load can reach 500 kilograms, while other poles are only about 200 kilograms.
8. High security
Pressure pattern lift rod adopts air pressure lifting, Rod body internal air pressure protection, accidents, air pressure buffer protection, will not fall directly from the height of more than 10 meters; While other rods are different, because the inside is steel wire rope, after rising, high load plus Rod body self-weight, the steel wire will easily break due to high load after long use, and the pole will fall directly from the high altitude, hurting people and damaging antenna equipment.
