PRODUCT DESCRIPTION
Product Description
The fixed pneumatic chain hoist is a common lifting equipment. Its working principle is to use compressed air as a power source to drive air to drive internal mechanical components to lift heavy objects. It is composed of a lifting mechanism, a traveling mechanism, and a gas distribution system. No sparks are generated and it has the characteristics of overload self-protection. It is the highest level of explosion-proof lifting equipment. It can be combined with explosion-proof hand-pulled or pneumatic trolleys to form mobile pneumatic lifting tools. It is a working-class M3, rated load of 50~32000kg, and a lifting height of 3m or customized.
Usage environment
Suitable for various working environments such as pollution, corrosion, toxic, flammable and explosive. Pneumatic hoists are extremely strong and reliable, suitable for a variety of harsh industrial application environments, and can operate sustainably. Mainly serving the coal mine, chemical fiber, textile, metallurgy, pharmaceutical industry, aerospace, offshore oil platform, shipbuilding and maintenance, chemical industry, and machinery manufacturing industries. Different control systems can be provided according to different needs. Hoisting loads above 25 tons are mostly used in the shipping industry to replace or install rudders and propellers, which can greatly speed up construction and increase efficiency.
Pneumatic hoist can also be used for material handling in various special environments. For example, in a high-temperature environment, the pneumatic hoist can avoid the problem of equipment failure caused by high temperature; In the explosion-proof environment, the pneumatic hoist can be used as an ideal explosion-proof equipment; In a corrosive environment, the metal material of the pneumatic hoist can resist the erosion of corrosive substances to ensure the long-term use of the equipment.
Product details
1. It has the function of gas cut-off protection, which ensures that the workpiece does not fall in the case of a sudden gas cut-off.
2. With a variety of non-standard fixtures, the pneumatic hoist can realize the lifting of various shapes of the workpiece.
3. Bearing support plane gear transmission system: can be used for full load continuous operation.
4. Resistance to high dust, acid, and alkali, steam.
5. Heavy Duty disc brakes Harrington's patented disc brake mechanism eliminates load drift and ensures fine feathering control.
6. Surface-hardened steel load chain galvanized and blue chrome plated, with corrosion resistance and long-term wear.
7. No electric spark, completely solves the problem of explosion-proof lifting equipment.
8. Lightweight compact body, easy to handle, and transport, and provide extra high headroom.
9. Hook and latch system galvanized and blue chrome, 360-degree rotation.
10. No lubrication. The pneumatic hoist is suitable for applications that require a clean environment. Gourds can be run completely dry, without lubrication in the exhaust, and are commonly used in the food, chemical, and pharmaceutical industries. (Note: The crane can also use oil to extend the life of the blade.)
9. Blade motor, allowing smooth operation and controlled driving.
10. Limit switch, the upper/lower limit switch is the standard of well protection, protecting the hoist from topping.

Authentication
All products of Dejun Company have passed ISO9001:2008 quality management system certification, and some products have American Petroleum Institute API certification, Mining Product Safety Mark Certification MA (KA), China Classification Society (CCS), American Bureau of Shipping (ABS) certification ) has EU CE certification, SGS certification, etc.
The difference between pneumatic hoist and electric hoist:
| Content | pneumatic hoist | electric hoist |
| Power | 0.6Mpa compressed air | 220V-440V voltage |
| Operating Speed | Adjustable and fast (4 times that of electric) | Not adjustable, slow |
| Secure | No sparks and electric shock | Leakage, sparks, easy electric shock |
| Structure | Pneumatic motors are simpler and smaller | Electric motors are large, heavy and require many parts to prevent sparks |
| Piping | No cables required, simple air pipe connection, no need for professionals to operate | It requires professionals to arrange it, which is cumbersome. |
| High-temperature Operation | Can work normally above 60 degrees | Abnormal operation may occur at high temperatures |
| Weight | Light, the weight is only 1/3~1/8 of the same size electric hoist. | heavier |
| Maintain | No professional training required | Requires professional maintenance |
| Life | The parts are processed with high precision, so they are suitable for frequent work and have long service life. | Electric motors have low efficiency, many parts are prone to wear and tear, and their lifespan is relatively short. |
Matters needing attention
1. Pipe configuration precautions:
① The distance between air compression and the workplace should be shortened as far as possible, considering whether the pipeline drainage is smooth or not.
② The main pipeline forms a network to facilitate maintenance and tracking of leak locations.
③ The shorter the pipeline in the work area, the better, forming a ring piping to reduce pressure drop.
2. Air pressure:
① The best air pressure for the work of the fixed pneumatic chain hoist is 0.6MPa (6kgf/cm2), the ability of the tool is reduced if the pressure is too low, and the pressure is too high, which can lead to accidents or failures.
② Air consumption and air compressor energy: To make the pneumatic hoist work, a certain amount of compressed air is necessary. The air consumption of 0.1m3 /min must be 0.75KW air compressor.
3. Precautions for safe use:
① Before using the air hoist, please read the operating instructions carefully to ensure the safety of use.
② Before use, check whether the tool is abnormal, whether the air pressure is normal, and whether the pipe winding situation.
③ When operating a pneumatic hoist, repairing a pneumatic hoist, or replacing accessories, please always wear impact-resistant eye masks and masks (face protection equipment). When not working, please turn off the air source first, and unplug the tool and air source joint.
④ Please keep a distance from the rotating axis and accessories, do not wear jewelry and fat clothes to use tools, and tie up long hair, scarves, ties, and other easily twisted things.
⑤ When operating, please wear labor protection devices and clothing.
⑥ Please do not point the air outlet at yourself or others.
4. Maintenance:
① The air source supplied to the fixed air chain hoist must be processed to ensure clean and dry.
② Please use an oil injector to lubricate the pneumatic hoist and adjust the flow rate to 2 drops per minute. If you do not use an oil injector, you must inject 3-4 drops of lubricating oil from the pipe joint every day. Do not use engine oil with high viscosity, which will cause the pneumatic hoist to rotate abnormally.
③ Do not throw or hit the pneumatic hoist.
