Tiger industrial air hoists are designed for, and proven in, many industries including mining, shipyards, offshore construction and power stations. They are also used for industrial and general engineering applications such as automotive plants, foundries, and heat treatment plants. The hoists operate at air pressures of between 4 and 6 bar. They comply with the requirements of ASME B30.16 and EN14492-2.
- Range – 5.0 tonne to 20.0 tonne
- Reliable, fast, efficient, quiet and lightweight
- Greater than 5:1 factor of safety
- Suitable for Fleeting/Oblique pulling
- Certified for ATEX Category 3 – normal safety
Temperature Range: Ambient temperature range -20°C to +70°C (for temperatures outside of this range please contact us for details).
Load Limiter: 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.
Emergency Stop: Pendant control hoists are supplied with a mains emergency stop valve. This shuts off the main air supply to the hoist when activated.
Precise Control: Accurate and precise positioning of loads is standard for both toggle and pendant control models.
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.
Fleeting, Cross Hauling or Oblique Pulling: This type of application is when the load deviates from the vertical position with a force acting directly between load hook and suspension point. Our air hoists can be used for fleeting and oblique pulling operations with no de-ration of the hoist. Cross hauling can be done with a single hoist, two hoists operated independently or with two hoists operated off one dual hoist pendant control.
Integral Silencer: The exhaust air silencer is built into the hoist gearbox housing and limits the noise level to below 85dB(A).
Load Chain: Grade 8 load chain ensures stringent high-speed duty cycles can be met. The load chain is in accordance with the requirements of EN818-7 Appendix B.
Vane Motor: Assisted vane lifting ensures maximum starting torque when starting under load.
Sealed Gearbox: 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.
