Explained: Why high-pressure hook loaders are better than lower-pressure alternatives
As the manufacturer of Ampliroll Hydraulic Hooklifts, we at Marrel are ready to clear up a common misconception regarding operating pressures among hook loaders. Before proceeding, here’s a word of background: As many in the industry know, Ampliroll products run at 4,500-5,000 PSI along with fully compatible piston pumps and actuators.
We didn’t pull this operating pressure out of a hat. It’s long been the standard for hooklifts in Europe. It’s proven itself in America, too. Fleet managers in the U.S. and Canada have relied on high-pressure hook loaders from Ampliroll for decades. They know that in all kinds of weather and every type of job, their performance and reliability come through—load after load, shift after shift.
Now you are being told (by some) that 4,500-5,000 PSI is too high.
To that claim, we respond that high-pressure systems like those used by Ampliroll are your best choice, and for several good reasons:
- Fact: The higher the hydraulic system pressure (to a certain point), the more efficient it is in transmitting horsepower between two points. Advantage: Ampliroll.
- Fact: Using a higher pressure reduces the size of actuators needed to achieve certain force requirements. With higher pressures and smaller actuators, heat is reduced. This reduces fuel consumption and permits lower reservoir sizes. Advantage x 2: Ampliroll.
- Fact: Smaller-size actuators usually equate to less weight. This results in more payload capacity where it counts the most—on the road, day after day in hook loader operations. Advantage: Ampliroll.
