Massive 32 L (8.5 Gallon) Tank and 2.5 HP Combine for Your Lifting Pleasure

We took a look at our 2.5 HP hydraulic power unit design and asked our engineers how we could “turn it up to 11,” so to speak. So why “turn up” when our power units already top the industry in smooth lifting? For one, we always look for ways to lift more efficiently. We took our hydraulic power unit with the largest motor and redesigned an 8.5-gallon tank for it. More fluid means more pressure can be exerted counter to the weight of a heavy vehicle. The largest, heaviest commercial trucks and SUVs that our car lifts can handle, including our multi-stacking parking lifts, can be serviced by this hydraulic power unit. Keep in mind, this particular unit’s 2,400 psi pressure relief valve is specially optimised to handle high-pressure situations, so you’re always covered when lifting the big stuff.

Operators can use this hydraulic power packs for both low-rise and full-size car lifts, including all of our vehicle parking systems, dock lifts and levellers, scissors lifts, material handling tables, tailgates, freight elevators or other applications that demand high performance and superb quality.

When “down” button is pressed, the car ​lift this power unit is mounted on will require less electricity in descent than when it rises. This is accomplished by the hydraulic power unit’s precision engineering, which accounts for the pull of gravity on the ​lift. Additionally, the entire case of the unit is sealed, protecting any internal parts from weather, oil, dust, debris, etc. To top it all off, this power unit works in a temperature range of -25 – 79°​C. That’s pretty incredible, if you think about it.

Our commitment to quality spans the entire production process, from engineering and manufacturing to packaging and shipping. Throughout every step of the manufacturing process, we utilise clean-room technologies for high-precision checking of all component parts going into our hydraulic power units. Our post-production examination procedures are structured to assure reliable performance and durability before any unit is packaged and shipped to customers around the globe.
