The AMGO RJ-20A rolling jack is built for extreme heavy-duty lifting up to 20,000 lbs, making it one of the highest-capacity jacks designed for use with four-post lift systems. It’s engineered to support full-size trucks, commercial vehicles, and other high-weight applications where stability and controlled lifting are critical. A heavy-duty reinforced structure and standard saddle adapter come included, ensuring secure engagement with the vehicle’s chassis right from setup.

What sets this model apart is how it handles both load stability and operator control under extreme weight. The pneumatic hydraulic pump delivers consistent lifting power for smooth elevation even under maximum capacity. Its double-screw frame saddle pad assembly improves contact with the vehicle frame, helping distribute weight more evenly and increasing stability during service work. Included 3" and 6" extension adapters allow technicians to adjust lifting height depending on vehicle clearance needs, making it more adaptable across different truck and commercial vehicle profiles.

For durability and long-term shop use, the RJ-20A uses a reinforced scissor structure and thickened sliding assembly, designed to keep the jack stable between runways during repeated heavy cycles. The floating roller system, made from hardened stainless steel with zinc plating, reduces wear and improves movement durability over time. A larger hydraulic cylinder supports stronger lifting force, while the integrated ergonomic guardrail handle improves maneuverability and protects the hydraulic hose during positioning.

This jack is best suited for commercial truck shops, fleet maintenance facilities, and heavy-duty service centers that regularly handle high-weight vehicles and need dependable lifting support inside four-post lift setups.
