Industrial Air Hoists TAH
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 1 and 6 bar. They comply with the requirements of ASME B30.16 and EN1L11192-2. Our manufacturing facility is 1S09001, 5014001 & OHSAS18001 certified.
- Range – 0.25t to 30t
- 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
More features of Tiger Air Chain Hoists
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 main emergency stop valve. This shuts off the main air supply to the hoist when activated.
Pendant Control Options
Our air hoists are supplied with either aluminum hard anodised controls which offer excellent corrosion protection or our Nickel plated SG iron option (for higher impact resistance combined with greater tensile strength and superior corrosion protection). Twist grip pendants are available as an option. Our new dual control pendant will operate two hoists with one pendant control. We also have a new remote control option available.
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.
Temperature Range
Ambient temperature range -4°F to +158°F (for temperatures outside of this range please contact us for details).
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.
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.
Optional Chain Carrier
Designed to carry and hold the length of load chain required for the operation, our stainless steel chain bucket is available in different size options. These chain carriers prevent loose chain from getting snagged during lifting or lowering operations and protect any loose chain during transit to and from the operational site.
ATEX
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).
