Zupper 20-ton Aluminum Hydraulic Cylinder RAC-2050

In critical sectors such as offshore maintenance, shipbuilding, and elevated infrastructure construction, the weight of standard steel cylinders presents a significant logistical challenge. Manually positioning heavy equipment in restricted or hazardous environments increases labor costs and operational risks.

The Zupper aluminum hydraulic jack RAC-2050 redefines high-capacity portable lifting. Forged from high-strength aerospace-grade aluminum alloy, this single-acting, spring-return cylinder delivers a massive 20 tons of hydraulic force while maintaining a highly compact form factor. It is the definitive choice for engineers who require professional-grade power in a portable package.

The aluminum advantage: Portability and marine-grade resistance

Transitioning to the RAC aluminum series provides two immediate operational upgrades over conventional steel models:

• Superior portability: Weighing significantly less than steel cylinders of the same capacity, the RAC-2050 can be easily carried and positioned by a single technician. This reduces the need for secondary lifting hoists during the setup phase, streamlining project timelines in hard-to-reach locations.

• Corrosion immunity: The hard-coat anodized finish on all aluminum surfaces resists the corrosive effects of saltwater and industrial chemicals. This makes the RAC-2050 an essential tool for shipyard turnarounds and offshore oil rig maintenance throughout Singapore and Malaysia.

Engineering directive: Hybrid design and side-load protection

A common misconception is that aluminum cylinders lack structural resilience. Zupper engineers have resolved this through a specialized "hybrid" architectural design:

• Steel contact points: The areas subjected to extreme friction—the baseplate and the top plunger saddle—are reinforced with hardened steel. This prevents load-induced deformation and protects the aluminum body from impact damage.

• 10% side-load resistance: Real-world lifting surfaces are rarely perfectly level. The RAC-2050 integrates advanced composite multi-wearing rings that prevent internal metal-to-metal contact. This allows the cylinder to safely absorb off-center side-loads of up to 10% of its total capacity without scoring the cylinder walls.

Technical specifications

Recommended power source: Zupper CP-700 manual hydraulic pump

For maximum reliability and field versatility, we recommend pairing the RAC-2050 with the Zupper CP-700 manual hydraulic hand pump. As the industry-standard power source, the CP-700 features a large oil reservoir and a dual-stage pumping mechanism. This ensures you have more than enough fluid capacity for the RAC-2050, while providing the 700-bar pressure required to achieve the full 20-ton lifting potential with minimal operator fatigue. Click here to view Zupper CP-700 manual pump specifications and pricing.
