Air Pneumatic Hoists: 4 Specialized Designs for Precision, Safety, and Harsh Environments

Air pneumatic hoists is also known as an air hoists. Pneumatic hoists is a kind of pneumatic power handling equipment, which uses compressed air as the power source, through the transmission mechanism, the balance of the object’s own gravity and the pressure in the cylinder to achieve the lifting and lowering movement of heavy objects.

Air Operated Hoist Performance Advantages 

Safety: 

• Powered by compressed air, non-sparking operation.
• With air break protection function, even if the air source is suddenly cut off, the heavy weight will not fall.
• With overload protection function, it is impossible to lift the weight that exceeds the rated load.
• Built-in centrifugal brake function prevents sudden and rapid lifting caused by misuse.

High efficiency: 

• Fast rising and falling speed, the fastest can be up to 1m/s. 
• Infinitely variable speed function, the rising speed can be freely controlled according to the lifting weight.

Precision: 

• With self-adaptive ‘floating' function, when the parts are lifted in a ‘gravity-free' state, it is easy to achieve precise positioning and assisted assembly.

Energy saving: 

• Extremely low air consumption, the average air consumption per working cycle is about 0.21m>/h, which is 1/50th of the air consumption of pneumatic hoists. 
• Clean and oil-free operation, can be used for a long time by pre-filling lubrication in the interior only.
• Small volume, no noise.

Pneumatic Air Hoist Structure

1. Ergonomic control handle

Is ergonomically manufactured for minimum size and light weight. The rise and fall buttons are equipped with adjusting screws to adjust the rise and fall speeds according to actual needs. At the same time, the control handle has mounting holes on the back, which can be combined with fixtures for mounting.

2. Centrifugal brake

If the load is suddenly removed or suddenly and unexpectedly raised, the brake will open to prevent the wire rope from suddenly retracting.

The method to release the brake is to press and hold the descending button, empty the pressure in the cavity, then pull the wire rope downward (different loads, the force required is different), and hear the ‘ticking' sound, indicating that the brake is released.

3.Mute ball screw 

The unique cycle design effectively prevents the wear and tear of the balls and prolongs the service life of the product.

4. Steel wire rope 

As a consumable part, our steel wire rope is made of pure imported steel wire rope from Germany, which is twisted with special steel wire for lifting, effectively preventing from breakage and scattering of strands, and has the performance of anti-abrasion and anti-corrosion.

5.Steel shell 

Sturdy all-steel shell, the cavity of the internal use of ultra-precision polishing technology, reducing friction, increasing the service life.

6.Engineering plastic reel 

It is made of high performance special engineering plastics, once processed and moulded, with excellent wear-resisting performance.

7.Piston 

As a wear part, our piston is injection moulded with special polyester compound, which has extremely low friction coefficient and wear resistance.

8.Suspension bracket 

The suspension bracket can be directly suspended from the hook, or directly connected to the KBK sliding trolley, I-beam trolley and so on. The suspension bracket can also be dismantled according to customer’s needs, and the shell lugs can be used to connect with the components.

9. The pneumatic valve is made of aluminium alloy, which is used together with the control handle to achieve the function of ascending and descending.

Parallel Wire Rope Air Pneumatic Hoist

Parallel Wire Rope Air Pneumatic Hoist with Sheave Block

Dimensional Parameters for Single-Line Wire Rope Air Pneumatic Hoist

Standard ‘floating' mode, 400mm up and down 

Maximum lifting weight is recommended to be around 80% of the rated load, exceeding this ratio will affect the floating performance.

Please contact us for special requirements.

Dimensions Parameters for Wire Rope Air Pneumatic Hoist with Sheave Block

The air pneumatic hoist with sheave block doubles the lifting capacity of the machine but halves the travelling distance.

Standard ‘floating' mode, 200mm up and down 

Maximum lifting weight is recommended to be about 80% of the rated load, exceeding this ratio will affect the floating performance.

Please contact us for special requirements.

Dimensions Parameters for the Parallel Wire Rope Air Pneumatic Hoist

The parallel wire rope air pneumatic hoist lifts twice as much as a single-line wire rope air pneumatic hoist without any influence on the travelling distance.

Standard ‘floating' mode, 400mm up and down 

Maximum lifting weight is recommended to be around 80% of the rated load, exceeding this ratio will affect the floating performance.

Please contact us for special requirements.

Dimensions Parameters for Parallel Wire Rope Air Pneumatic Hoist with Sheave Block

In order to increase the rated load, some of the products are connected in parallel with additional dynamic pulleys, which results in a lifting capacity four times that of the basic model.

Standard ‘floating' mode, 200mm up and down 

Maximum lifting weight is recommended to be about 80% of the rated load, exceeding this ratio will affect the floating performance.

Please contact us if you have special requirements.

Air Driven Hoist Parameter Table:

The actual lifting capacity is mainly determined by the input pressure, for every 0.1MPa decrease in input pressure, the actual lifting capacity decreases by 10%.

The maximum lifting weight is recommended to be about 80% of the rated load, exceeding this ratio will affect the floating performance.

Please contact us if you have special requirements.

Suspension Types Are as Follows:

Fixed Hook Type

I-Beam Trolley Type

Sliding Trolley Type

Advantages of Air Pneumatic Hoists Over Electric Hoists: 

• Fast rising and falling speeds, usually 2-6 times faster than electric hoists 
• ‘Floating' function, easy to achieve precise positioning 
• Very high working system, 24 hours uninterrupted operation 
• Compressed air as the driving force, non-sparking operation is safer 
• Relying on the screw drive, smooth and jitter-free rising and falling, and can be infinitely variable speeds.
