Hydraulic Oil Pressure = Capacity All hooklift hoists are preset, at the factory, to achieve intended lifting capacity. Turning up the system's pressure will increase lifting capacity, but adjusting or tampering with hoist's pressure settings may result in system failure (extreme overload) and most likely void manufacturer's warranty. Flow Rate = Cycle Speed Increasing the engine speed will allow for faster hoist operation.

  • Hydraulic Oil Pressure = Capacity All hooklift hoists are preset, at the factory, to achieve intended lifting capacity. Turning up the system's pressure will increase lifting capacity, but adjusting or tampering with hoist's pressure settings may result in system failure (extreme overload) and most likely void manufacturer's warranty. Flow Rate = Cycle Speed Increasing the engine speed will allow for faster hoist operation. Use caution, as extended periods of engine reving may damage the hydraulic system and/or pump. High-Pressure/Low Volume Systems This was the original approach used by early European models and is still widely used today. This setup appeals to chassis with space restraints, allowing for use of the smaller piston pump and smaller hydraulic reservoir. This may not be the ideal approach if planning to share the hoist's hydraulic system with other hydraulically powered devices. These systems operate between 4,000 to 5,800 PSI. Low-Pressure/High Volume Systems As the concept entered the North American market, it continued its evolution, offering an alternative hydraulic solution. This setup is ideal for operators who require the ability to share the hoist's hydraulic system with other hydraulically powered devices, like spreaders and water tanks. This system typically operates with the larger gear pump and larger hydraulic reservoir. Even though tagged as a low-pressure system, it actually operates under medium pressures. These pressures range from 2,000 to 3,500 PSI. For a quick lesson in hydraulics, visit the Gates Corporation website for Hydraulics 101 or Wikipedia's Hydraulic Machinery.
