WORLD CLASS WINCHES

RELIABLE - DEPENDABLE - UNCOMPLICATED

4       Winch basics
4.1    Hydraulic System Basic Information
4.1.1 General

Hydraulics is a topic in applied science and engineering dealing with the mechanical 

properties of liquids. Fluid mechanics provides the theoretical foundation for hydrau-

lics, which focuses on the engineering uses of fluid properties. These fundamentals 

of hydraulics apply to SEPSON winches.

Note

You cannot obtain maximum oil pressure and maximum oil flow at the same 

time. This means that maximum pulling force and maximum rope speed 

cannot occur at the same time.
