Introduction to the use of explosion-proof pneumatic hoist

1、 Core advantages

Inherent explosion-proof design

Using compressed air as the power source, it completely avoids the explosion risk caused by electric sparks or high temperatures in electric hoists, and is suitable for flammable and explosive places such as petroleum, chemical, and coal mines (such as Class IIC T5 hazardous areas). The shell is made of aluminum alloy or explosion-proof alloy material, and the sealing structure meets explosion-proof standards (such as Ex d IICT4), ensuring safe operation in gas, dust and other environments.

Efficient and stable homework

Fast response and speed regulation: Start delay<0.5 seconds, support continuously variable speed (speed range 20-28 m/min), 2-3 times that of electric hoists, meeting high-frequency start stop requirements.

Accurate positioning: centimeter level positioning is achieved through pneumatic proportional valves, suitable for scenarios such as automotive assembly and precision machining.

Continuous operation capability: The pneumatic system has no risk of overheating and can operate continuously for 24 hours, suitable for scenarios such as automated production lines and logistics warehousing.

Multiple security protections

Cut off braking: When suddenly cut off, the spring brake instantly locks to prevent the workpiece from falling.

Overload protection: When the load exceeds the rated value, the pneumatic motor automatically slows down or stops to avoid equipment damage.

Explosion proof fixture adaptation: With non-standard fixtures, it can lift irregular workpieces and reduce the risk of collision.

2、 Applicable scenarios

High risk industrial environment

Petrochemical industry: Lift oil tanks and reactor covers to avoid explosions caused by static sparks.

Coal mining: Lifting equipment in underground tunnels to withstand environments with high gas concentrations.

Spray painting workshop: Lift painted workpieces to prevent electrical sparks from igniting solvent vapors.

Special working condition requirements

High temperature and high dust: In scenarios such as steel smelting and cement plants, it can withstand high temperatures of 60 ℃ and dust erosion.

Clean production: Oil free lubrication system prevents contamination of sensitive components (such as semiconductor manufacturing).

Wet environment: IP67 protection level supports underwater or humid area operations.

Continuous operation production line

Automobile manufacturing: Lifting heavy objects such as engines and vehicle bodies in the final assembly line and welding line can increase efficiency by 40%.

Logistics warehousing: Collaborate with AGV vehicles to achieve rapid transportation of goods, increasing turnover efficiency by 25%.

3、 Key points of operation and maintenance

Installation and commissioning

Choose a flat and solid ground to ensure that the pitch and turning radius of the track meet the requirements (long slope conditions require limited usage time).

Check the sealing of the joint when connecting the gas source to prevent air leakage and insufficient pressure.

No load test run to check if all components are normal, such as limit switches, safety valves, etc.

Daily operations

Follow the principle of "slow start, slow stop" to avoid equipment damage caused by emergency stop and start.

Maintain stable connection between the hook and the object to prevent accidents caused by shaking.

Real time monitoring of operating status, immediately stop the machine for inspection if any abnormal sounds or vibrations are detected.

Maintenance

Regularly replace lubricating grease to maintain good lubrication of components such as bearings and gears.

Check the wear of cylinders and seals, and replace aging components in a timely manner.

Clean the surface dust and oil stains of the equipment to prevent impurities from entering the pneumatic or electrical system.

4、 Selection suggestions

Select according to load requirements

Small tonnage (250kg-5 tons): suitable for precision assembly, laboratory and other scenarios.

Large tonnage (10-30 tons): Used for heavy-duty scenarios such as mining equipment lifting and large container handling.

Select by structure type

Loop chain pneumatic hoist: compact structure, suitable for short distance vertical lifting.

Ultra low pneumatic hoist: with low clearance height, suitable for confined spaces.

Mini pneumatic hoist: small in size, light in weight, easy to carry and move.

Select by industry adaptation

Chemical industry: Prioritize the selection of corrosion-resistant materials (such as stainless steel chains) and products with high explosion-proof ratings.

Automobile manufacturing: Choose models that support stepless speed regulation and precise positioning to improve assembly efficiency.

Logistics warehousing: equipped with pneumatic carts or guide rail systems to achieve horizontal movement function.
