Principle of pneumatic hoist and operation of pneumatic hoist

Description :

　　Pneumatic hoist is currently the ideal explosion-proof lifting equipment in the region, and is an upgraded product of electric hoist. Its load range varies from 250 kilograms to 30 tons depending on the model. Pneumatic hoists only require a certain pressure of compressed air to drive, achieving low energy consumption and high efficiency. It also has a gas cut-off protection function, which ensures that the workpiece does not descend or fall 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 coordinated 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 shipbuilding, it is an essential equipment for enterprise safety production, improving efficiency, and reducing costs.

　　Classification of pneumatic hoists: Loop chain pneumatic hoist, Type pneumatic hoist (low net air pneumatic hoist), Mini pneumatic hoist, etc. Pneumatic hoist can be combined with explosion-proof hand pulled trolley or pneumatic trolley to form a mobile pneumatic lifting tool.

　　Cylinder type is also mainstream; The blade type is represented by JDN; There are many companies producing piston type, while blade type will become the future development direction.

　　Working principle of pneumatic hoist: Pneumatic hoist has always had good sales, so what is its working principle?

　　The pneumatic chain hoist consists of three parts in total:

　　1. Lifting mechanism

　　2. Walking mechanism

　　3. Valve system

　　The lifting mechanism includes a pneumatic motor, planetary reducer, suspension assembly, brake, lifting chain, hook assembly, and main control valve. The lifting mechanism controls the main control valve to achieve the lifting and lowering of heavy objects, and achieves the positioning braking of lifting and lowering by opening and closing the brake. The pneumatic chain hoist ensures the safety of lifting operations. The lifting mechanism of the pneumatic hoist can be fixed for use as a whole or moved under the walking mechanism for use

　　The pneumatic hoist walking mechanism adopts a pneumatic walking trolley, consisting 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 when lifting heavy objects.

　　The air distribution system uses compressed air as a power source to control the lifting and walking of the pneumatic control hoist.

　　Advantages of pneumatic hoist: positioning - avoiding the problem of positioning for ordinary lifting products, it can position the load to "centimeters".

　　Adjustable speed - can be infinitely adjusted during lifting or lowering; The operating speed is fast, three times that of an electric hoist; 5-10 times that of a chain hoist.

　　Easy to operate - The lever control is simple and easy to control, and can quickly respond to the action output by 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 damp, high dust, etc.

　　Effortless handling - Pneumatic hoists not only focus on their appearance, but also have a smaller volume, lighter weight, and are easier to handle compared to electric hoists. Additionally, their solid product structure design ensures reliable operation and minimal maintenance.

　　Overload protection - benefiting 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 key brake system and low maintenance production technology in the process, avoiding damage to the product caused by overloading of the load.

　　Air supply interruption protection - to prevent sudden drop of heavy loads caused by sudden interruption of gas supply. To provide further quality assurance for the product, thereby eliminating the inconvenience caused by end users experiencing improvement or detachment.

　　Durable - Pneumatic hoists are durable and have a significantly extended service life compared to similar products. This significantly reduces complaints from end users about product quality issues.
