  Pneumatic hoist is the world's most ideal explosion-proof lifting equipment. Commonly used pneumatic hoist blade type, piston type and cylinder type three.

  It is mainly composed of four parts, namely, gas distribution system, power system, deceleration system and winch system.

 

  Introduction to pneumatic hoist

  Widely used in petroleum, chemical industry, coal mine, textile, warehousing, household appliance production line, automobile production line and ship repair and other industries, is an enterprise safety production, improve efficiency, reduce costs of essential equipment.

 

  Pneumatic hoist classification

  Ring chain pneumatic hoist, ultra-low pneumatic hoist (low headroom pneumatic hoist), mini pneumatic hoist and so on. Pneumatic hoist can be combined with explosion-proof hand trolley or pneumatic trolley to form a mobile pneumatic lifting tool. Cylinder type is also mainstream; Vane type is represented by German JDN; Piston type has many companies in the production, compared with the blade type will become the future development direction.

  Pneumatic hoist has been a good sales, so its working principle is what?

  Ring chain pneumatic hoist is composed of three parts:

  1. Lifting mechanism

  2. Walking mechanism

  3. Gas distribution system

 

  Pneumatic hoist working principle

  Lifting mechanism includes pneumatic motor, planetary reducer, lifting assembly, brake, lifting chain, lifting hook assembly and main control valve. Lifting mechanism through the control of the main control valve, to achieve the lifting of heavy objects, down, through the open and close brake to achieve the lifting, falling positioning brake. Ring chain pneumatic hoist to ensure the safety of lifting operation, Yale pneumatic hoist lifting mechanism can be fixed as a whole, can also be placed under the walking mechanism to move to use.

  Pneumatic hoist walking mechanism adopts pneumatic walking trolley, which is composed of active wheel, passive wheel and wallboard. Pneumatic motor and planetary reducer are controlled by the main control valve to drive the active wheel to walk, so as to achieve horizontal movement of lifting heavy objects.

  The gas distribution system takes the compressed air as the power source, controls the air path to control the hoist's lifting and walking.

 

  Advantages of pneumatic hoist

  Precision positioning

  --Avoid the general lifting product positioning is not accurate, can be the load positioning accurate to "cm".

  Adjustable speed

  --Stepless speed regulation is available when lifting or descending; Running speed, is three times the electric hoist; 5-10 times as much as pulling the gourd by hand.

  The operation is simple

  --The pull rod control operation is simple and easy to control, when lifting or descending, thus can quickly respond to the action of the handle output.

  Clean, environmentally friendly, safe and reliable

  --The internal lubrication system eliminates air pollution. Suitable for working in damp, high dust and other special or harsh environment.

  Handling and effort

  --Pneumatic hoist in addition to pay attention to the appearance of beautiful, smaller than electric hoist, light weight, easy to carry, and product structure design solid, so that the operation of reliable, small maintenance.

  Overload protection

  --Benefit from our company for many years in the domestic and international markets continue to study the crystallization of successful experience, and combined with the strict screening of raw materials. JM pneumatic hoist in the process of fully grasp the most critical brake system and low maintenance of production technology, to avoid overload on the product damage.

  Barely able to protect

  --Avoid sudden interruption of air source and sudden drop of load. The product has further quality assurance, so as to eliminate the end user to suffer from lifting or falling off the trouble.

  Durable

  --Pneumatic hoist durable, service life than the general similar products have significantly extended. Thus greatly reduce the end users to product quality problems complaints.

 

  Pneumatic hoist application range

  Due to the good explosion-proof performance of pneumatic hoist, it is widely used in chemical industry, textile, spray paint, logistics, wharf and other inflammable, explosive, high temperature, high dust, corrosion, strong workplace. Because it has high frequency, infinitely variable speed characteristics, by the output of large, continuous operation of strong automobile, tractor, motor, refrigerator and other manufacturing industries and logistics industry favor. In particular, some industrial developed countries clearly stipulated that petroleum, chemical, automobile, mining and other inflammable and explosive occasions, must be forced to use pneumatic hoist

  Pneumatic hoist is the upgrading product of electric hoist, has been widely used in all walks of life, bearing range according to different models from 250 kg to 30 tons. Pneumatic hoist only to provide a certain pressure of compressed air can drive, to achieve low energy consumption, high efficiency. It also has the function of air break protection, in the case of sudden air break, to ensure that the workpiece does not fall, fall.

  With a variety of non-standard clamps, pneumatic hoist can be used to lift workpieces of various shapes. The installation can be carried out by means of cantilever crane or guide rail.
