50 kN Pneumatic Hoisting Winch
50 kN Pneumatic Hoisting Winch
A 50 kN pneumatic hoisting winch with secondary braking, built in Yatala for hoisting duty in a mine where compressed air is the only permitted power source and two independent brakes are required.
Pneumatic Winch Project Overview
A custom-built 50 kN pneumatic hoisting winch with secondary braking for mining
A 50 kN pneumatic hoisting winch with secondary braking, built for hoisting duty in a mine where compressed air is the permitted power source and electrical equipment is excluded from the work area. An air motor drives the winch through a gearbox, and two independent brakes act on the drive train: a spring-applied brake that clamps whenever air is removed, and a secondary Enerpac cylinder brake that gives a second, separate means of holding the load, a requirement for hoisting in many underground and processing environments. The winch carries 100 m of rope on a blue and yellow frame, and was engineered, built and load tested at our Yatala, Queensland workshop before being crated for delivery.

Operational & Technical Breakdown
An in-depth look at the 50 kN pneumatic hoisting winch's performance and technical capabilities
The winch frame carries a grooved drum for 100 m of rope at 50 kN, a gearbox and a pneumatic motor fitted with a silencer, with the drive guarded and the whole unit sized to fit through mine access ways. There is no electrical component anywhere on the machine: motor, valves and brake actuation all run on plant air, so the winch introduces no ignition source into the work area.
Braking is doubled up. The primary spring-applied brake is held off by air pressure and clamps the drive automatically if supply is lost or the control released. The secondary brake is an Enerpac air cylinder acting on a separate brake element, so the load is held even if the primary brake or its actuation fails. Both brakes were proven under rated load during testing at Yatala, and the winch was delivered in a timber crate with test certificates and RPEQ sign-off.
Other Winch Applications
Versatile winching solutions across multiple industries.
Beyond mining, pneumatic hoisting winches with secondary braking suit refineries, chemical plants and any hazardous area where lifting equipment must be air-powered and redundantly braked.
Hoisting in refinery and gas plant zones where electrical equipment is excluded – air-driven winches with fail-safe and secondary braking for hazardous areas.
Deck hoisting and cargo handling on tankers and at fuel terminals – pneumatic winches for hazardous-area duties with marine-grade protection.
Project Conclusion
The 50 kN pneumatic hoisting winch combines air drive with two independent brakes to meet the hoisting rules of a hazardous mining environment. Designed, built and tested in Yatala by Australian Certified Winches.
Like every winch we build, it was designed to AS 1418, the Australian Standard for cranes, hoists and winches, and signed off by our RPEQ-registered engineers before load testing in Yatala.

Frequently Asked Questions
Common questions about pneumatic hoisting winches with secondary braking.
What is secondary braking and why is it required?
A second brake that works independently of the primary brake, so the load is still held if the primary brake or its actuation fails. Many mining and hazardous-area hoisting standards require two independent means of holding a suspended load, and this winch was built to meet that.
How does the secondary brake work on this winch?
An Enerpac air cylinder applies a separate brake element on the drive train. It is controlled independently of the primary spring-applied brake, so the two can never fail for the same reason, and both were tested under rated load at Yatala.
Why is the winch pneumatic rather than electric?
The work area excludes electrical equipment because of the explosion risk. An air motor, air-operated valves and air-actuated brakes give a hoisting winch with no electrical ignition source, running from the plant compressed air supply.
What line pull and rope capacity does it have?
The winch is rated at 50 kN line pull with 100 m of rope on the drum. ACW matched the air motor and gearing to the plant air pressure and flow to deliver that pull at a controlled hoisting speed.
Was the winch certified for lifting?
Yes. It was designed and load tested to AS 1418 as hoisting equipment, with both brakes proven under load, and supplied crated with test certificates and RPEQ engineering sign-off for the mine’s lifting register.
Hoisting Where Power Is Excluded?
Tell us the load, the lift and the air supply on site. Our RPEQ engineers will size a certified pneumatic hoist with secondary braking for it.
