pneumatic hoist
Introduction to pneumatic hoist products
Pneumatic hoist is currently the most ideal explosion-proof lifting equipment in the world. It is an upgraded product of electric hoist, with a load-bearing range ranging from 250 kilograms to 30 tons depending on the model. The pneumatic hoist can be driven by providing compressed air with a certain pressure, achieving low energy consumption and high efficiency. It also has a gas cut-off protection function, which ensures that the workpiece does not fall or drop in case of sudden gas cut-off. Combined with various non-standard fixtures, pneumatic hoists can lift workpieces of various shapes. The installation form can be combined with a cantilever crane or guide rail to achieve movement. There are three commonly used pneumatic hoists: blade type, piston type, and cylinder type. Widely used in industries such as petroleum, chemical, coal mining, textile, warehousing, household appliance production lines, automobile manufacturing production lines, and ship repair, it is an essential equipment for enterprise safety production, improving efficiency, and reducing costs.
Classification of pneumatic hoists
Chain pneumatic hoist, ultra-low type pneumatic hoist (low purity air hoist), mini pneumatic hoist, etc. The pneumatic hoist can be used in conjunction with explosion-proof hand pulled carts or pneumatic carts to form a mobile pneumatic lifting tool. Cylinder type is also mainstream; The blade type is represented by JDN; The piston type is being produced by many companies, and compared to the blade type, it will become the future development direction.
Working principle of pneumatic hoist
The pneumatic hoist has always had good sales, so what is its working principle? The chain pneumatic hoist consists of three parts: 1. lifting mechanism 2. walking mechanism 3. air distribution system lifting mechanism including pneumatic motor, planetary reducer, suspension assembly, brake, lifting chain, hook assembly, and main control valve. The lifting mechanism controls the main control valve to lift and lower heavy objects, and achieves lifting and lowering positioning braking through the opening and closing brake. The pneumatic chain hoist ensures the safety of lifting operations. The lifting mechanism of the pneumatic hoist can be fixed as a whole or placed under the walking mechanism for mobile use. The walking mechanism of the pneumatic hoist adopts a pneumatic walking car, which is composed of active wheels, passive wheels, and wall panels. The main control valve controls the pneumatic motor and planetary reducer to drive the active wheels to move horizontally, achieving the horizontal movement of lifting heavy objects. The gas distribution system uses compressed air as the power source to control the lifting and walking of the pneumatic hoist.
Advantages of pneumatic hoist
Accurate positioning - avoids the problem of inaccurate positioning of ordinary lifting products, and can accurately position the load to "centimeters". Adjustable speed - stepless speed regulation during lifting or lowering; The running speed is three times faster than that of an electric hoist; 5-10 times that of a chain hoist. Easy to operate - The lever control operation is simple and easy to control, so that it can quickly respond to the output action of the handle when lifting or lowering. Clean, environmentally friendly, safe and reliable - the internal lubrication system eliminates air pollution. Suitable for working in special or harsh environments such as moisture, humidity, and high dust. Effortless Handling - Pneumatic hoists not only focus on aesthetic appearance, but also have smaller volume, lighter weight, and easier handling compared to electric hoists. Additionally, the product structure is designed to be solid, ensuring reliable operation and minimal maintenance. Overload protection - benefited from the successful experience of our company's continuous research in domestic and international markets over the years, combined with rigorously screened raw materials. JM pneumatic hoist has fully mastered the most critical brake system and low maintenance production technology in the process, avoiding damage to the product caused by overloading of heavy objects. Gas outage protection - to prevent sudden interruption of gas supply and sudden drop of load. To provide further quality assurance for the product, thereby eliminating the problem of end users experiencing improvement or detachment.
Durable - The pneumatic hoist is durable and has a significantly extended service life compared to similar products. This significantly reduces the number of complaints from end users about product quality issues.
