Integrated Design and Engineering Excellence
The foundation of this Central Hydraulic System is its 30-gallon reservoir assembly, meticulously fabricated from premium 304 stainless steel. The selection of 304 stainless steel is not arbitrary; it is a critical engineering decision driven by its superior corrosion resistance, high tensile strength, and excellent durability in harsh environmental conditions. This material withstands exposure to road grime, de-icing salts, corrosive chemicals, and extreme weather, ensuring an extended service life and minimizing the need for premature replacement or costly repairs. The reservoir’s substantial 30-gallon volume is optimized to provide sufficient hydraulic fluid capacity for continuous operation across multiple high-demand functions, while also contributing to effective heat dissipation, which is crucial for maintaining fluid integrity and system efficiency.
Integral to the reservoir assembly is a robust valve enclosure, also constructed from durable materials, featuring a secure, latching stainless steel lid. This enclosure serves a vital protective function, shielding the critical spreader, hoist, and plow valves from physical damage, environmental contaminants, and adverse weather conditions. The strategic mounting of all directional valves and spreader controls directly onto the tank assembly is a hallmark of intelligent design. This consolidated arrangement significantly streamlines hydraulic plumbing, reducing the number of external hoses, fittings, and connection points. The result is a cleaner, more organized installation with fewer leak paths, simplified diagnostic procedures, and expedited service interventions. This approach not only enhances operational reliability but also translates into substantial savings in installation time and labor costs.
The Power Core: Hydraulic Specifications and Performance Parameters
The hydraulic power unit is engineered for robust performance, capable of delivering a maximum flow rate of 40 GPM (gallons per minute) and sustaining a maximum system pressure of 3000 PSI (pounds per square inch). The main relief valve is factory-set at 2500 PSI, providing a critical safety and operational threshold to protect the system components from over-pressurization while ensuring sufficient power for demanding tasks. The system's inlet port is specified as 3/4 SAE ORB (-12) and the outlet port as 2 NPT, facilitating standard and robust connections to the hydraulic pump and return lines, respectively. The suction port, also a 2 NPT, is adequately sized to ensure efficient fluid intake, preventing cavitation and promoting smooth pump operation. These specifications underscore the system's capacity to handle the energetic demands of simultaneous, heavy-duty operations.
Advanced Filtration and Fluid Management
Maintaining hydraulic fluid cleanliness is paramount for the longevity and efficiency of any hydraulic system. The Buyers Products Central Hydraulic System integrates a comprehensive filtration and fluid management strategy. It includes an in-tank return filter assembly with a 25-micron rating and a flow rating of 50 GPM. This fine filtration capability effectively captures particulate contaminants from the returning hydraulic fluid before it re-enters the reservoir, preventing wear on sensitive components such as valves and cylinders. Furthermore, a 150-micron suction filter with a 49 GPM flow rating is incorporated to protect the main hydraulic pump from larger debris, ensuring a clean supply of fluid at the pump inlet.
Beyond filtration, the system incorporates a filler-strainer breather cap assembly. This component is dual-purpose: it allows for clean replenishment of hydraulic fluid while simultaneously providing filtered air exchange with the atmosphere, preventing the ingress of airborne contaminants and moisture. A shielded sight temperature gauge provides operators with a continuous, at-a-glance indication of the hydraulic fluid level and temperature. This allows for proactive monitoring of fluid conditions, enabling operators to identify potential issues such as overheating or low fluid levels before they lead to system damage or operational downtime. Additionally, a magnetic drain plug is included, which attracts and retains ferrous metal particles, offering an additional layer of protection against wear and serving as an early indicator of internal component degradation.
Precision Control: Six-Function Air/Hydraulic Proportionality
The system's designation as a "6-Function" unit signifies its capability to independently control up to six distinct hydraulic operations, providing comprehensive power and versatility for vocational truck applications. The implementation of air/hydraulic proportional controls is a significant advancement over traditional on/off hydraulic systems. Proportional control allows for variable speed and force adjustments, enabling smooth, precise, and infinitely adjustable manipulation of implements.
- Plow System Control (Lift, Angle Left, Angle Right): The system allocates 11 GPM for plow operations, controlled by a 3-way valve for lift/lower and a 4-way valve for left/right angle. Proportional pneumatic controls offer operators the ability to "feather" the plow blade, achieving incremental adjustments in height and angle with exceptional accuracy. This precision is critical for effective snow removal and grading, minimizing surface damage and maximizing operational efficiency. The two integrated port reliefs, rated at 1800 PSI for the angle function, provide essential protection against over-pressure events during dynamic plow movements or impacts, safeguarding hydraulic cylinders and hoses. The power up/power down action ensures active control in both directions.
- Hoist System Control (Power Up/Power Down): A dedicated 30 GPM 4-way double-acting (DA) dump hoist valve provides robust power for lifting and lowering truck beds. The inclusion of a down port relief set at 500 PSI precisely manages the lowering speed and prevents shock loads on the hoist cylinder. The "power beyond" feature allows for continuous hydraulic flow to additional downstream components even when the hoist is operating, maximizing the system's utility without sacrificing performance. Proportional pneumatic controls ensure smooth, controlled hoist movements, enhancing safety and preventing abrupt shifts of cargo.
-
Spreader System Control (Auger/Conveyor, Spinner, Pre-wet): The spreader functions benefit from highly sophisticated electric-over-hydraulic proportional control, managed by the HVC06T spreader controller. This control type is crucial for optimizing material spreading operations.
- Auger/Conveyor Port (3/4 SAE ORB -12): Proportional control of the auger or conveyor system ensures a consistent flow of material from the hopper to the spinner. This variable flow capability is fundamental for precise material dosage, preventing over-application and ensuring even distribution.
- Spinner Port (1/2 SAE ORB -8): Proportional control of the spinner motor allows operators to finely adjust the spread width and pattern. This enables adaptive spreading strategies based on road conditions, traffic, and environmental factors, reducing material waste and improving coverage uniformity.
- Pre-wet System: For GPS-equipped systems, a 3-function control option includes a proportional pre-wet function. This allows for the precise application of liquid anti-icing agents to dry granular materials, enhancing their effectiveness and adhesion to road surfaces. The integrated controller supports programmable blast (1-30 seconds) for targeted material application and features a low-pressure pre-wet indicator, alerting operators to potential issues with the liquid system.
GPS-Enabled Intelligent Spreading System
The inclusion of an optional, integrated GPS-based ground speed control system represents a significant leap in spreader technology, transforming variable manual control into intelligent, automated material management. With the GPS module installed, the system continuously monitors vehicle speed and automatically adjusts the flow rate of spreading materials (e.g., salt, sand, or liquid de-icers) to maintain a consistent application rate per unit area, regardless of the truck's speed.
This automated adjustment provides several critical advantages:
- Optimized Material Usage: By eliminating over-application in slower zones and under-application in faster zones, the GPS system significantly reduces material waste. This translates into substantial cost savings on spreading materials and reduces environmental impact.
- Consistent Coverage: Ensures a uniform level of salt or other material coverage across all treated surfaces, regardless of variations in vehicle speed due to traffic, terrain, or operator adjustments. This leads to more effective ice and snow control.
- Enhanced Operational Efficiency: Operators can focus more on driving and less on constantly adjusting spreader settings, reducing fatigue and improving overall safety. The system's automation minimizes human error, ensuring optimal performance across different shifts and operators.
- Data-Driven Decision Making: The GPS system can provide valuable data logs (application rates, distances, speeds, materials used), which can be utilized for post-operation analysis, route optimization, compliance reporting, and inventory management.
- Expanded Liquid Application Capabilities: For systems with GPS, the controller can manage both pre-wet and broader liquid spray functions. This allows for diverse liquid application strategies, from anti-icing brines to dust suppression, all controlled with precision. The programmable blast function enables short bursts of material, useful for intersections or specific problem areas.
