Markets
Hydraulic systems are essential in spreaders (used in agriculture, construction, and municipal applications) to power components like spreading mechanisms, conveyor belts, and lifting arms. Below is a detailed breakdown of hydraulic products used in spreaders, along with high-market-share brands and models:
1. Hydraulic Motors
Role: Drive the spreading mechanism (e.g., spinner discs, augers) and conveyor systems.
Types:
Gear Motors: Cost-effective for medium torque.
Piston Motors: High torque for heavy-duty spreading.
High-Market-Share Models:
Parker Hannifin MGG Series (e.g., MGG 10001): Compact, high-torque gear motors.
Eaton Char-Lynn 2000 Series (e.g., 211-XXX): Low-speed, high-torque motors for precise control.
Bosch Rexroth AZPF Series: Axial piston motors for heavy-duty applications.
Danfoss OMM/OMV Series: Orbital motors for compact spreaders.
2. Hydraulic Pumps
Role: Generate fluid flow to power motors and cylinders.
Types:
Gear Pumps: Common in small to medium spreaders.
Piston Pumps: For high-pressure, high-efficiency systems.
High-Market-Share Models:
Parker PGP Series (e.g., PGP505): Gear pumps for reliable flow.
Eaton 20 Series (e.g., 72456): Piston pumps for variable displacement needs.
Bosch Rexroth A10VO Series: Axial piston pumps for high-pressure systems.
3. Hydraulic Control Valves
Role: Regulate flow direction and pressure for actuators.
Types:
Directional Control Valves: Manage spreader functions (start/stop, speed).
Proportional Valves: Enable precise flow adjustment.
High-Market-Share Models:
HydraForce SV08/SV10 Series: Compact solenoid valves for directional control.
Parker D1VW Series: Manual valves for simple systems.
Bucher Hydraulics QX Series: Proportional valves for automated spreaders.
4. Hydraulic Cylinders
Role: Control hopper gates, lifting arms, or adjustable spread patterns.
Types:
Single/Double-Acting Cylinders: For linear motion.
High-Market-Share Models:
Parker Hannifin 2H/3H Series: Robust cylinders for heavy loads.
Eaton Clevis/Tie-Rod Cylinders (e.g., 104-XXX): Durable and customizable.
5. Hydraulic Hoses & Fittings
Role: Transport fluid between components.
Key Brands:
Gates UltraFlex II Hoses: High-pressure, abrasion-resistant.
Parker Hannifin 791HT Hoses: Flexible and temperature-resistant.
6. Hydraulic Power Packs
Role: Integrated systems combining pumps, motors, and valves.
High-Market-Share Models:
Hyvair HPU Series: Compact units for small spreaders.
Bailey Hydraulics Mobile Power Packs: Customizable for large spreaders.
7. Hydraulic Filters & Reservoirs
Role: Maintain fluid cleanliness and storage.
Key Brands:
Donaldson Hydraulic Filters (e.g., P550597): High-efficiency filtration.
Parker Hannifin Spin-On Filters: Easy maintenance.
8. Hydraulic Manifolds
Role: Centralize valve mounting for compact systems.
Key Models:
Sun Hydraulics Custom Manifolds: Modular designs for complex circuits.
Top Brands in Spreader Hydraulics
Parker Hannifin (dominant in motors, pumps, valves).
Eaton (Char-Lynn motors, piston pumps).
Bosch Rexroth (high-pressure pumps and motors).
Danfoss (orbital motors for compact systems).
HydraForce (modular valves for precise control).
Example Spreader Hydraulic System
Motor: Eaton Char-Lynn 211-1020 (drives spinner disc).
Pump: Parker PGP505 (supplies flow).
Valve: HydraForce SV08-22 (controls direction).
Cylinder: Parker 2H Series (adjusts gate opening).
Considerations
Application: Smaller agricultural spreaders use gear motors, while municipal salt spreaders require piston pumps for high torque.
Customization: Brands like Hyvair and Bailey offer tailored power packs.
For specific models, consult manufacturers like Vicon (agricultural spreaders) or BOSS Snowplow (salt/sand spreaders), which integrate these hydraulic components.
