A hydraulic power source mounted on a tractor unit, provides pressurized fluid to operate remotely located hydraulic equipment on a trailer or other machinery. This system allows the semi-truck to power equipment such as dump trailer cylinders, walking floor trailers, or even remotely operated machinery at a construction site. For instance, a dump trailer utilizes hydraulic cylinders powered by this system to lift the trailer bed for unloading materials.
The installation offers significant operational flexibility. It eliminates the need for auxiliary power units on trailers, reducing weight and maintenance costs. Historically, these systems emerged as a solution to power increasingly sophisticated trailer functionalities, increasing the versatility of semi-trucks beyond simple hauling. Their adoption has streamlined operations in industries ranging from construction to agriculture, enabling efficient material handling and specialized equipment operation.
