Tiger TAH-M Twin Hook Pneumatic Air Hoist – 2t-6t WLL

Description

Tiger TAH-M Twin Hook Pneumatic Air Hoist

The Tiger TAH-M Twin Hook Pneumatic Air Hoist is a specialist heavy-duty lifting and pulling solution developed for demanding industrial applications. Originally designed for the mining industry, the TAH-M is now used across marine, offshore, industrial and hazardous environments where reliable pneumatic lifting equipment is essential.

Available with working load limits from 2t to 6t, the TAH-M operates from a compressed air supply of 4-6 bar and provides a 100% continuous duty cycle. This makes it particularly well suited to repetitive lifting, pulling and positioning applications where prolonged operation is required.

The balanced motor design delivers consistent power, while the integral load limiter provides overload protection in both lifting and pulling directions. The hoist is also equipped with a fail-safe, self-adjusting disc brake that automatically engages when the air supply is interrupted.

With variable-speed control, multiple pendant options and a range of hook configurations, the Tiger TAH-M can be configured to suit a wide range of industrial lifting and pulling applications.

Twin Hook System – Benefits & Advantages

The twin hook configuration is one of the key features of the Tiger TAH-M. Unlike a conventional single-hook hoist, the twin hook arrangement provides additional flexibility for applications where controlled lifting and pulling are required.

Balanced Load Control

The twin hook design allows the lifting or pulling forces to be distributed through the two hook points, helping provide more controlled load handling. This can be particularly beneficial when working with larger or awkward loads where maintaining stability is important.

Lifting and Pulling Capability

The TAH-M is designed for both lifting and pulling operations, making it a versatile solution where loads need to be moved, positioned, tensioned or retrieved rather than simply lifted vertically.

Greater Application Flexibility

The twin hook system can provide greater flexibility when connecting the hoist to different load configurations and lifting arrangements. A range of hook configurations is available, including standard, closed eye, grab and self-locking hooks.

Improved Control for Demanding Loads

With balanced motor operation and dual-direction overload protection, the TAH-M provides controlled operation when handling demanding loads. This makes it suitable for applications where precise movement and controlled pulling forces are required.

Ideal for Heavy-Duty Industrial Applications

The twin hook arrangement makes the TAH-M particularly suitable for mining, marine, offshore, shipyard and industrial applications where lifting and pulling requirements can vary during the same operation.

Important: The appropriate lifting arrangement, accessories and connection points must always be selected according to the load, application and manufacturer’s instructions. The hoist’s stated WLL must not be exceeded.

100% Continuous Duty Pneumatic Operation

The Tiger TAH-M operates using compressed air at 4-6 bar, providing a 100% duty cycle for continuous operation.

Unlike many electrically powered lifting systems, pneumatic operation allows the hoist to continue operating during demanding repetitive lifting cycles without the same duty-cycle limitations associated with many electric motors.

This makes the TAH-M particularly suitable for:

• Mining operations
• Shipyards
• Offshore installations
• Marine applications
• Industrial maintenance
• Manufacturing
• Heavy engineering
• Continuous lifting and pulling operations

Pneumatic operation can also be advantageous in hazardous environments where avoiding electrical equipment and potential sources of ignition is important.

Dual-Direction Overload Protection

The TAH-M incorporates an integral differential pressure load limiter designed to provide overload protection in both lifting and pulling directions.

The load limiter prevents the operator from exceeding 125% of the working load limit, with the protection remaining effective across the hoist’s operating pressure range.

This provides an additional level of protection for the hoist, load and operator during demanding lifting and pulling operations.

Fail-Safe Disc Brake

A non-asbestos, self-adjusting disc brake automatically engages when the compressed air supply is shut off.

The fail-safe brake is designed to hold more than 125% of the WLL, providing secure load holding when the control is released or the air supply is interrupted.

The self-adjusting design also helps maintain reliable braking performance throughout the service life of the brake.

Precise Variable-Speed Control

The Tiger TAH-M provides smooth and variable control through a range of operating configurations.

Available controls include:

• Lever control
• Pilot pendant
• Direct pendant
• Nickel-plated SG iron emergency-stop pendant
• Twist-grip pendant
• Toggle control

This allows operators to achieve accurate load positioning and controlled movement during lifting, pulling and handling operations.

Heavy-Duty Construction

The TAH-M is designed for demanding industrial environments and incorporates a number of features intended to maximise reliability and service life.

The sealed planetary gearbox uses heat-treated gears and low-friction bearings to withstand demanding duty cycles, while the balanced vane motor provides high starting torque when operating under load.

An integral silencer keeps operating noise below 83dB(A).

The hoist’s modular construction also provides straightforward access to key components including the:

• Motor
• Brake
• Gearbox
• Load limiter

This simplifies servicing and can help reduce maintenance downtime.

Grade 8 Load Chain

The TAH-M is fitted with Grade 8 load chain designed for demanding lifting applications.

The chain complies with SANS/ISO 3077 and EN818-7 Appendix B, providing the strength and durability required for high-duty industrial lifting and pulling operations.

ATEX Certified for Hazardous Environments

The Tiger TAH-M is available with ATEX Category 3 certification for hazardous environments.

Its ATEX designation is:

Ex II 3 GD c IIB T4 IIIB T135°C

This makes the hoist suitable for:

• Zone 2 gas environments
• Zone 22 dust environments

This is particularly relevant to applications such as offshore installations, shipyards, refineries, mining and other industrial environments where potentially explosive atmospheres may be present.

Available Hook Configurations

The TAH-M can be supplied with a range of hook configurations to suit different lifting and pulling applications.

Available options include:

• Standard hooks
• Closed eye hooks
• Grab hooks
• Self-locking hooks

The correct hook and lifting accessories should be selected according to the specific application and load requirements.

FRL System Recommended

Tiger recommends operating the TAH-M with a suitable Filter Regulator Lubricator (FRL) system.

An FRL unit:

• Filters water and contaminants from the air supply
• Regulates operating pressure
• Lubricates the pneumatic motor
• Helps maintain consistent hoist performance
• Protects internal motor components

Tiger recommends installing the lubricator within 3 metres of the hoist, using ISO VG10 light oil and a 10-micron airline filter.
