Pneumatic Air Bag Jack Rockforce RF-TRA1812 3 t capacity (h min 135 mm, h max 400 mm)

Rockforce RF-TRA1812 is a pneumatic air bag jack with a 3 t lifting capacity and an adjustable height range from 135 mm to 400 mm. The device uses compressed air to inflate a reinforced rubber bladder that produces a stable vertical lift, making it suitable for lifting cars, light trucks and other heavy equipment where a compact, portable solution is required. The jack is designed for workshop and roadside use and offers quick deployment and simple operation compared with conventional mechanical jacks.

Advantages

The pneumatic air bag jack provides fast, controlled lifting by inflating a durable air bladder, reducing manual effort. Its compact footprint and comparatively low minimum height allow access under vehicles with limited ground clearance. The wide maximum height range offers flexibility for different repair and maintenance tasks. Constructed with reinforced materials and integrated safety features, the unit aims to deliver stable support and consistent performance when used on appropriate surfaces.

Suitable for

• Lifting passenger cars and light commercial vehicles for tire changes or underbody inspection
• Roadside assistance and emergency lifting where rapid deployment is needed
• Workshop tasks that require a compact, portable lifting solution
• Maintenance of small trailers, lawn equipment and other light machinery

When it may not be suitable

This pneumatic air bag jack has a rated capacity of 3 t and is intended for vehicles and equipment within that limit; it should not be used for loads that exceed the specified capacity. The jack requires a source of compressed air to operate, so it is not suitable in locations where compressed air is unavailable unless a portable compressor is carried. For unstable, soft or uneven ground, additional support such as solid jack stands or a firm, level base is necessary because the air bladder needs a stable surface to provide safe lifting.

Key specifications

• Lifting capacity: 3 t
• Minimum height: 135 mm
• Maximum height: 400 mm
• Operation: pneumatic (compressed air inflation)
• Design: reinforced rubber air bladder with protective cover
• Typical applications: vehicle and light equipment lifting

How to use

Position the jack on a firm, level surface beneath a recommended lifting point on the vehicle or equipment. Connect the jack to a suitable compressed air source following the manufacturer’s pressure recommendations and safety guidelines. Inflate the air bladder gradually while monitoring lift progress and ensuring the load remains stable. Once the desired height is reached, secure the vehicle with appropriate supports such as jack stands before performing maintenance. To lower, slowly release air from the bladder while monitoring the descent until the load is fully supported by the ground.

What to consider before purchase

• Verify that your vehicle or equipment weight does not exceed the 3 t rated capacity.
• Ensure access to a compatible compressed air source or portable compressor for operation.
• Consider the minimum height (135 mm) to confirm the jack will fit under the intended lifting points.
• Plan for using additional safety supports (jack stands) and a firm, level surface during lifting.

Usage recommendations

Use the pneumatic jack on solid, level ground and always employ approved jack stands or blocks after lifting. Follow compressed air pressure limits and inspect the air bladder and fittings regularly for wear or damage. Do not exceed the 3 t capacity and avoid side loads or angled lifting that could compromise stability.
