Buyers Products 30 Gallon Central Hydraulic System - 6 Function, Electric-Hydraulic Proportional is an all-in-one way to power and operate a hoist, plow, spreader, and pre-wet system. The system is easy to install and even easier to use. Features like in-cab electric controls are ideal for installers and operators alike. By eliminating the need to plumb multiple hydraulic lines into the cab, the controls cut down install time, save cab space, and keep the heat and noise outside the cab. An optional GPS-based ground speed control system gives spreader operators superior control over material usage. With the GPS installed, the spreader will automatically adjust its flow rate based on vehicle speed. This ensures a proper level of salt coverage regardless of how fast or slow the truck is moving. The Central Hydraulic System includes everything you need to set up a 6-function plow, spreader, and hoist system. Simply install the reservoir assembly and plumb the flow and functions. All directional valves and spreader controls are mounted directly on the tank to streamline plumbing and make service simple. The 30 gallon reservoir assembly with valve enclosure is built from 304 stainless steel to stand up to road grime, salt, and inclement weather. It includes an in-tank return filter assembly, filler-strainer breather cap assembly, and a shielded sight temperature gauge. The valve enclosure features a latching stainless steel lid to provide the spreader, hoist, and plow valves additional protection. The system is ideal for medium to heavy duty applications. All Systems Include: Proportional spreader operation with compact 2-function or 3-function (GPS versions only, includes auger-conveyor, spinner, and pre-wet functions) controls. Proportional pneumatic plow and hoist controls. 11 GPM 3-way plow lift/4-way plow angle with two port reliefs. 30 GPM 4-way DA dump hoist with down port relief and power beyond. Color TFT-LCD touchscreen display. Optional Additions:GPS with capability for pre-wet and liquid spray functions in one convenient controller, including programmable blast (1-30 seconds) and low pressure pre-wet indicator. Please contact Customer Service for further options. Applications that require critical load holding, installer must use P.O. (Pilot Operated) checks or counterbalance valves as well. Includes everything you need to set up a plow, spreader, and hoist hydraulic system for your truck.
