TAH-M Twin Hook Air Hoist
Tiger twin hook air hoists were originally designed for mining applications and suitable for both pulling and lifting operations. Now deployed globally in various marine and industrial applications. The hoist uses a balanced motor with our integral load limiter working on both sides. This dual action gives overload protection in both directions for lifting and pulling. They comply with the requirements of SANS 1638, EN14492-2 and ASME B30.16. Our manufacturing facility producing the hoists is ISO9001 certified.

Advantages of Air Hoists
Air-powered hoists are ideal for tasks that require rapid lifting speeds and constant use. These hoists are powered by a compressed air feed, making them a great alternative to electric hoists when there are no power sources available. Another key benefit of air hoists is their 100% duty cycle – significantly higher than most electric hoists. For example, an electric chain hoist that has a 25% duty cycle can be operated continuously for a maximum of 15 minutes in a one-hour period. Hoists that are powered by a compressed air feed do not have this limitation; they can remain in constant use until the job is done.
Integral differential pressure load limiting valve automatically prevents the operator lifting a load of more than 125% of the working load limit. Load limiter is 100% repeatable at all working pressures and does not wear or generate damaging heat.
Lever control, pilot pendant control and direct pendant control offer variable speed control. Accurate and precise positioning of loads is standard for both toggle and pendant control models. Various lock out options available.
Fail Safe Disc Brake
Non-asbestos self-adjusting disc brake is applied automatically when the air supply to the hoist is shut off. The brake is self-adjusting for the life of the brake and can hold more than 125% of the working load limit.
The exhaust air silencer is built into the hoist gearbox housing and limits the noise level to below 83dB(A).
Grade 8 load chain ensures stringent high speed duty cycles can be met. The load chain is in accordance with the requirements of SANS/ISO 3077 and EN818-7 Appendix B.
Assisted vane lifting ensures maximum starting torque when starting under load.
The sealed planetary gearbox ensures that the most stringent duty cycles can be met. The gears are heat treated and mounted on high strength, low friction bearings.
Ease of Maintenance
The modular design of the hoist allows easy access to internal components such as the motor, gearbox, brake and load limiter. Common parts are used throughout the range.
Manufactured in accordance with ATEX Directive 2014/34/EU and Machinery Directive 2006/42/EC and suitable for ATEX Category 3 – normal safety. Our products are assigned as follows: ATEX marking: : Ex II 3 GD c IIB T4 IIIB T135°C. Suitable for gas and dust hazardous areas: Zone 2 (gas) and Zone 22 (dust). Unlike electrically operated hoists, the air driving pneumatic air hoists doesn’t produce any sparks making them suitable for application in explosion-hazardous areas.
