A hydraulic power system installed on a semi-truck, often referred to as a “wet kit,” provides auxiliary hydraulic power to operate external equipment. This system typically consists of a hydraulic pump, a reservoir for hydraulic fluid, control valves, and necessary hoses and fittings. For example, a truck equipped with this system can power a dump trailer, a walking floor trailer, or other hydraulically driven accessories.
The value of such a system lies in its versatility, enabling a single truck to perform a wider range of tasks. This increases efficiency and reduces the need for specialized vehicles. Historically, these systems became popular as trucking operations diversified, requiring trucks to not only transport goods but also actively participate in loading, unloading, and material handling processes.
