Choosing an Air Hoist
by Al Madden

 Choosing a Pneumatic Hoist

Why should you use a pneumatic hoist rather than an electric hoist?

  • Continuous Duty Cycle
  • Infinitely variable Speed control (between limits).
  • Hassle-free maintenance due to smaller, simpler construction
  • Self cooling
  • Portability
  • Internal air pressure protects internal components from external air contaminants
  • No electrical components to cause sparks or arcing in explosive areas

When should you use a pneumatic air hoist rather than an electric hoist?

  • When a good air supply of air (80 - 100 PSI) is readily available
  • When variable speed control is required
  • When long lifts and continuous operations must be performed without overheating
  • When precise spotting of the load is needed
  • When work environment sustains high ambient temperatures
  • When spark resistance is required due to explosives or hazardous areas (Optional spark-resistant features such as bronze hooks, bronze wheels and stainless chain are available to meet specific requirements.)
  • When dust, moisture, or corrosive atmospheres require for the sealing protection inherent in an air motor
  • When working in a "clean-room" environment, such as food processing and pharmaceuticals

Choosing an air chain hoist

  • Choose a rated capacity no greater than half the strength of the structure from which it will be hung.
  • For medium and heavy-duty applications, choose a capacity rating that is no less than the maximum load to be lifted, as well as approximately 155% of the mean load to be lifted.
  • Choose a pneumatic hoist with the highest speed available that will not cause safety or spotting problems.
  • Choose a hook mount (unless the inch or so gained with lug mounting is important, or if you are going to use a motorized tractor to move the load).
  • Choose an air-powered tractor above two-ton capacity.
  • Choose a dual-braking system when redundant safety is required to keep the load suspended.
  • Choose an air chain hoist with pendant push button controls to address ergonomics and safety considerations.
  • Choose a pneumatic air hoist with pull cord controls when cost and simplicity are the prime considerations.
  • Choose an air hoist with grease in the gear case, when oil contamination must be avoided.
  • Choose an air chain hoist for readily available repair parts and easy maintenance.

Additional Considerations

  • Keep in mind that ball bearing life in hoist equipment varies inversely according to the cube of the load. Operating your hoist at a lower mean effective load will amount to huge savings in repairs and downtown.
  • Always use an approved filter lubricator with your air hoist to reduce repair costs and downtime.
  • When using stainless steel chain (for spark- or corrosion-resistance), you should down rate the chain capacity, because stainless load chain does not have the breaking strength of standard alloy load chain.
