Power Up, Power Down & Gravity Down Hydraulic Control for Dump Trailers

The KTI DC-45416 (also sold as DC-4747) is a 12-volt double-acting hydraulic power unit engineered for dump trailers, equipment trailers, and commercial hydraulic applications requiring both powered lift and powered lowering.

Choose a 3-quart reservoir for compact builds or a 6-quart reservoir for larger cylinders and higher duty cycles. Includes a 3-button wired remote (Power Up / Power Down / Gravity Down) with a built-in manual override at the pump for emergency operation if the remote ever fails — a critical reliability feature for field work.

Built to OEM specifications used by Load Trail, Diamond C, Lamar, and other commercial dump trailer manufacturers.
