Plow Trucks

Plow trucks, also known as snowplow trucks or snowplows, use hydraulic systems to operate the plowing mechanisms and effectively clear snow and ice from roads. The hydraulic equipment on plow trucks plays a crucial role in controlling the plow blade and other components. Here are some common hydraulic components and equipment used on plow trucks:

Hydraulic Power Unit (HPU):

The hydraulic power unit includes a hydraulic pump, tank (reservoir), and associated components. It generates hydraulic power to operate various hydraulic functions on the plow truck.

Plow Blade Lift Mechanism:

Hydraulic cylinders are used to lift and lower the plow blade. The operator can adjust the height of the blade to accommodate different snow depths and road conditions.

Plow Angle Adjustment:

Hydraulic cylinders or motors may be used to adjust the angle of the plow blade. This allows the operator to direct snow to a desired side while plowing.

Wing Extension (Optional):

Some plow trucks have wing extensions that can be hydraulically extended or retracted. These extensions increase the effective width of the plow, allowing for more efficient snow clearing.

Down Pressure Control:

Hydraulic systems may include features to apply downward pressure on the plow blade. This feature helps improve the blade's contact with the road surface for effective snow removal.

Salt Spreader (Optional):

If the plow truck is equipped with a salt spreader, hydraulic systems may be used to control the rate and distribution of salt or other de-icing materials.

Hydraulic Hoses and Fittings:

High-pressure hydraulic hoses and fittings connect various hydraulic components, ensuring a secure and leak-free flow of hydraulic fluid.

Hydraulic Tank:

The hydraulic tank (reservoir) stores hydraulic oil needed for the operation of the hydraulic system, ensuring a continuous supply of oil to the pump and cylinders.

Pneumatic Controls (Optional):

Pneumatic controls may be used in conjunction with hydraulic systems for certain functions, providing additional flexibility and control.

Safety Features:

Plow trucks often include safety features in the hydraulic system, such as pressure relief valves and interlocks, to ensure safe and controlled operations.

Electric or Manual Controls:

Controls for the hydraulic system can be electrically operated or manually operated, allowing the operator to control various functions from the plow truck's cab.

Proper maintenance and regular inspections of the hydraulic system are essential to ensure the reliable and safe operation of plow trucks. The specific features and design of hydraulic systems can vary among different types and models of plow trucks.
