Pneumatic winch (Air winch)

Product Overview

Pneumatic winch(Air winch) is a traction/lifting equipment driven by compressed air. and its core power source is pneumatic motor.

Compared with electric or hydraulic winches, it has the characteristics of explosion-proof, high temperature resistance, and impact resistance, and is especially suitable for flammable, explosive, dusty or humid environments (such as mines, oil fields, and chemical plants).

Structure and working principle: Pneumatic motor: converts the kinetic energy of compressed air into mechanical energy to drive the drum to rotate.

Speed reduction device: adjusts the output torque and speed to meet different load requirements.

Braking system: adopts pneumatic friction brake or spring brake, and automatically locks when power/gas is cut off.

Wire rope/chain: standard diameter 6-20mm, traction range 1-50 tons (customizable). ‌Workflow: Compressed air → pneumatic motor → speed reduction box → drum rotation → wire rope retraction and release → complete traction/lifting.

Depending on your actual use, there are different winch for customers to choose from.

We have an experienced team of crane engineers.

We design the right winch type for you, and provide a full range of after-sales services to enable your winch to operate quickly, stably and reliably.

Key Advantages

This crane model is engineered for long service life and low maintenance in demanding industrial environments. Buyers choose it because it is built by the factory itself, with steel structure processed by CNC cutting and automated welding for dimensional accuracy and consistent quality.

• Self-locking function ensures that heavy objects are stationary
• Air drive to avoid electric sparks
• Air cut-off protection, high safety
• Stepless speed control, easy installation
• Small size, light weight, strong traction
• Environmentally friendly, no pollution

Main Features

Every Pneumatic winch (Air winch) leaves the factory complete with the following standard features, verified during final inspection and load testing:

• Strong safety ‌ ‌ Explosion-proof and flame-proof‌: No electric drive is required, no electric sparks are generated, and it can be safely used in flammable and explosive gas or dust environments (such as methane, oil and gas environments). ‌Self-locking when the air supply is cut off‌: When the air source is cut off, the brake system automatically locks the reel to prevent heavy objects from falling. ‌Overload protection‌: The pneumatic system balances the risk of overload through the pressure relief characteristics to avoid equipment damage.
• Flexible operation‌ ‌Stepless speed regulation‌: Continuous speed adjustment (5–30 m/min) is achieved through the handle or remote control to meet the switching needs of light and heavy loads. ‌Precise control‌: Supports centimeter-level positioning accuracy (such as pneumatic hoist linkage scenes) to improve work efficiency. ‌Multi-scenario compatibility‌: It can be controlled manually, remotely or by PLC programming to meet basic operation and automation needs. ‌
• Strong environmental adaptability‌ ‌Resistant to harsh environments‌: The protection level reaches IP65, which can withstand high dust, moisture, corrosive media and extreme temperatures from -30℃ to +80℃‌. ‌Resistant to shock loads‌: Pneumatic systems have natural adaptability to vibration, high temperature and shock loads, and have high stability‌.
• Structural and maintenance advantages‌ ‌Lightweight and compact‌: Small size and light weight (compared with hydraulic/electric equipment), easy to carry and install underground‌. ‌Low maintenance cost‌: No complex circuits, the lubrication system is closed and dustproof, with low failure rate and simple maintenance‌. ‌Long life design‌: The service life of key components (such as solenoid valves and cylinders) is tens of millions of times, and the durability is strong‌.
• Energy efficiency and environmental protection‌ ‌Energy saving and environmental protection‌: Powered by compressed air, without oil pollution, in line with green operation requirements‌. ‌Low cost operation‌: The air source is easy to obtain, and the energy consumption and maintenance costs are lower than those of hydraulic or electric systems‌. ‌
• Typical application scenarios ‌Petrochemical/Mining: Explosion-proof 13 + Corrosion-resistant; ‌Port/Ship: Waterproof and moisture-proof 5 + Impact-resistant; ‌Automated production line: Precise positioning 5 + PLC linkage control. (Note: Some functions need to be customized according to specific models. It is recommended to confirm with the supplier based on the working conditions.)

Applications & Working Conditions

The Pneumatic winch (Air winch) is used across industrial plants, warehouses, steel mills, power stations, ports and logistics centers. It is available with optional lifting attachments such as lifting beams, electromagnets, grabs, C-hooks and coil tongs for special material handling.

Standard models operate in ambient temperatures from -20°C to +50°C. For special environments, we can supply explosion-proof electrics, high-temperature paint systems, dust-proof protection or corrosion-resistant coatings. Tell us your working condition and our engineers will confirm the correct configuration.

Customization Options

We customize span, lifting height, working class, control mode (pendant, wireless remote or cabin), and add frequency conversion speed control, explosion-proof protection or special coatings to suit your environment. Tell us your requirements and our engineers will prepare a tailored proposal.

Standard Supply Scope

Your order includes the complete crane structure, travelling mechanism, hoisting trolley or hoist, electrical control system, safety devices (limit switches, overload limiter, buffers, emergency stop), operation manual and inspection certificates. Optional extras include wireless remote control, frequency inverter, cabin with heater/air conditioner, lighting and special lifting attachments.

Quality Control & Testing

All structural welding is performed by certified welders and inspected before painting. Each crane undergoes no-load and full-load testing on our test bench, including brake test, limit switch verification and electrical safety check. Third-party inspection (SGS or buyer-nominated) is available before shipment.

Packing & Shipping

Cranes are shipped in knockdown form with steel structure, wheels, trolley, electrics and hardware carefully packed to prevent damage during ocean freight. Export packing follows our standard seaworthy specification, with wooden cases for electrics and control panels. Delivery options include FOB, CIF and DDP to your port.

Installation & After-Sales

We offer installation supervision and commissioning by our engineers, or fully turnkey installation by our experienced team. After commissioning we provide operator and maintenance training, a complete documentation package, and 24/7 spare parts and technical support for the lifetime of the crane.

What to Include in Your Inquiry

To receive an accurate quotation, please send us the following details with your inquiry: required lifting capacity (ton), span or working radius, lifting height, duty / working class, control method (pendant, radio remote or cabin), power supply voltage, site environment (indoor, outdoor, high temperature, dusty, explosion-proof area), and quantity. The more detail you provide, the faster our engineers can confirm the design and price.
