Size and Capacity: The size of the hydraulic cylinder should be carefully selected to match the specific snowplow's requirements.
Common sizes range from 2 inches to 4 inches in diameter, with larger cylinders typically offering greater lifting capacity. The capacity of the cylinder is typically measured in pounds or tons and should be adequate to lift the weight of the plow blade and handle the anticipated snow load.
Material: The cylinder's body is typically constructed from high-strength steel, which can withstand the harsh operating conditions encountered during snowplowing. The material should be corrosion-resistant to ensure long-term durability in cold and wet environments.
Sealing: Double-acting cylinders have two ports, one for extension and one for retraction. High-quality seals are essential to prevent hydraulic fluid leakage and ensure reliable operation. Common seal materials include rubber, polyurethane, or Teflon, with the choice depending on factors such as temperature, pressure, and fluid compatibility.
Stroke Length: The stroke length refers to the maximum distance the cylinder can extend and retract. Snowplow cylinders typically have stroke lengths ranging from 6 inches to 24 inches, allowing for precise control of the plow blade's position.
Pressure Rating: The cylinder's pressure rating must match the hydraulic system's operating pressure.
Snowplow hydraulic systems typically operate at pressures between 2,000 and 3,000 PSI (pounds per square inch).
Mounting Options: The cylinder should have compatible mounting options to seamlessly integrate with the snowplow's framework. Common mounting options include clevis mounts, trunnion mounts, and eye mounts, which allow for secure attachment and efficient force transmission.
Rod Diameter: The rod diameter plays a role in the cylinder's strength and durability. A larger rod diameter can withstand higher forces but may increase the overall size and weight of the cylinder.
Piston Type: Snowplow cylinders often use a piston with a durable, wear-resistant surface, such as chrome plating or nitriding, to reduce friction and extend the cylinder's lifespan.
