Sweeper Trucks

Sweeper trucks, also known as street sweepers or road sweepers, use hydraulic systems to power various components that facilitate street cleaning and debris collection. The hydraulic equipment on sweeper trucks is critical for controlling the sweeping mechanisms and ensuring effective cleaning operations. Here are some common hydraulic components and equipment used on sweeper trucks:

Hydraulic Power Unit (HPU):

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

Sweeping Brushes:

Hydraulic motors are often used to drive the rotating brushes on the sweeper. These brushes sweep debris from the road surface and into the collection system.

Adjustable Broom Height:

Hydraulic cylinders may be used to adjust the height of the sweeping brushes, allowing the operator to adapt to different road surfaces and debris types.

Collection System:

Hydraulic systems control the collection system, which typically includes conveyors, augers, or other mechanisms that transfer swept debris into the hopper for storage.

Hopper Dumping Mechanism:

Hydraulic cylinders are commonly used to lift and tilt the hopper for dumping the collected debris at a designated disposal site.

Vacuum System (Optional):

Some sweeper trucks incorporate a vacuum system for additional debris collection. The vacuum system may include hydraulic components such as fans or blowers to create suction.

Water System:

Hydraulic systems can be used to control water spray nozzles for dust suppression during sweeping operations. This is often important in dry conditions to minimize airborne particles.

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:

Sweeper 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 sweeper truck's cab.

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