Pneumatic Winch Series

A pneumatic winch (or air-powered winch) is a lifting/pulling device driven by compressed air instead of electricity or hydraulics. It converts pneumatic energy from an air compressor into mechanical motion to wind or unwind a cable/drum. Widely used in hazardous environments (e.g., explosive atmospheres, mines, oil rigs) where sparks or electricity pose risks.

Pneumatic Winch/Air Winch

Key Features & Advantages

Explosion-Proof Operation—No electrical components, eliminating fire/explosion risks in flammable environments (e.g., chemical plants, mines).
Lightweight & Compact Design—Simpler structure than hydraulic/electric winches, easier to install in confined spaces.
Low Maintenance—Fewer moving parts, resistant to dust, moisture, and corrosion.
Overload Safety—Air motors stall harmlessly under excessive load, preventing damage.
Temperature Resilience—Operates reliably in extreme temperatures (-40°C to +120°C).
Instant Start/Stop—Quick response to air pressure changes, enabling precise control.

Pneumatic Winch Equipment

Parameter	Typical Range	Notes/Applications
Load Capacity	0.5 – 50 tonnes	Custom designs may exceed 30T for specialized uses (e.g., mining).
Line Speed	2 – 50 m/min	Higher speeds (30-50 m/min) for light loads (<5T); lower speeds (2-10 m/min) for heavy loads (>20T).
Air Pressure Requirement	0.4 – 1.2 MPa (4 – 12 bar)	High-torque models require 8-12 bar.
Air Consumption	80 – 3,500 L/min	Scales with load: ~500 L/min for 5T, ~2,500 L/min for 30T.
Drum Capacity	10 – 1,000 meters	Large drums (>500m) for marine/offshore towing.
Cable/Rope Diameter	5 – 40 mm	Steel wire (5-30mm) or synthetic rope (10-40mm).
Weight	25 – 3,000 kg	Compact models for confined spaces; heavy-duty versions for industrial rigs.
Noise Level	65 – 90 dB(A)	Quieter than diesel winches; louder at high loads.
Motor Power	0.5 – 50 HP (0.37 – 37 kW)	High-power motors (30-50 HP) for 30-50T loads.
Control Type	Lever/Foot pedal/Remote valve	Explosion-proof remote controls for hazardous zones.
Safety Factor	4:1 – 8:1	8:1 for critical lifting (offshore/platforms).
Operating Temperature	-50°C to +150°C	Wide range for Arctic operations or high-heat industrial sites.
IP Rating	IP65 – IP69K	IP69K for high-pressure washdown environments.

Key Observations Of Air Winches

Tonnage Flexibility:
- <5T: Light-duty tasks (warehouse lifting, small boats).
- 5-20T: General industrial use (construction, logging).
- 20-50T: Heavy-duty applications (oil rigs, shipyards).
Trade-offs:
- Higher tonnage = Lower line speed + Higher air consumption.
- Extreme temperatures may require specialized seals/lubricants.
Standards Compliance:
- ATEX/IECEx certifications for explosive atmospheres.
- ISO 4308/4309 for safety and performance.

Example: A 30T pneumatic winch for offshore use might operate at 8 m/min with 40mm steel rope, 25 HP motor, and IP68/IP69K rating for saltwater resistance.
