Hydraulic Bottle Jack Sourcing ROCKFORCE FROG 3T 135–465 mm, 2‑Piston

Hydraulic bottle jack Sourcing ROCKFORCE FROG 3T is a compact vertical lifting tool designed for lifting vehicles and heavy equipment within a rated capacity of three tonnes. The unit features an adjustable stroke range from 135 mm to 465 mm and a two-piston design that enables staged lifting. Supplied with a standard pumping mechanism and built-in safety bypass, the jack is intended for repair, maintenance and industrial applications where stable, space-efficient lifting is required.

Advantages

The two-piston system allows initial rapid extension followed by fine adjustment, reducing pumping effort and saving time when positioning loads. The compact bottle form factor and vertical lift capability make the jack suitable for confined spaces and service pits. A safety bypass prevents hydraulic overload, and robust construction provides reliable performance under regular workshop and field use.

Suitable for

• Lifting passenger cars and light commercial vehicles within a 3-ton limit
• Support tasks in vehicle repair and routine maintenance
• Raising industrial equipment for inspection or component replacement
• Use in mobile service vans and compact workshop environments

Key specifications

• Lifting capacity: 3 tonnes
• Lifting range (adjustable stroke): 135 mm – 465 mm
• Design: hydraulic bottle jack with two-stage/two-piston mechanism
• Operation: manual pumping hydraulic system with release valve
• Function: vertical lifting for service and maintenance

How to use

Place the jack on a firm, level surface under the vehicle or equipment at a manufacturer-approved lifting point. Ensure the load is within the 3-ton capacity. Close the release valve, operate the pumping handle to extend the piston and raise the load to the desired height. For staged lifting, the two-piston design provides a faster initial lift followed by finer adjustment; monitor alignment and stability while lifting. To lower, open the release valve slowly and control the descent. Always use appropriate stands or supports before performing work beneath a lifted load.

Usage recommendations

Use the jack on solid, level ground and verify load limits before operation. Inspect the hydraulic unit for leaks or damage prior to each use, and follow routine maintenance such as checking hydraulic fluid levels and keeping moving parts clean. Do not exceed rated capacity and always secure the load with appropriate supports to prevent accidental lowering.
