Aerial Trucks

Aerial trucks, also known as aerial work platforms or cherry pickers, use hydraulic systems to operate the lifting and positioning mechanisms that allow workers to reach elevated areas. These hydraulic systems are essential for the safe and controlled movement of the aerial platform. Here are some common hydraulic components and equipment used on aerial 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 aerial truck.

Telescopic Boom:

Hydraulic cylinders extend and retract the telescopic boom, allowing the aerial platform to reach different heights. The boom may also have multiple sections, each controlled by hydraulic cylinders.

Articulating Boom (Optional):

Some aerial trucks have an articulating boom that can bend or flex at specific joints. Hydraulic cylinders control the articulation, providing additional reach and flexibility.

Lift Mechanism:

Hydraulic cylinders control the lifting mechanism, allowing the aerial platform to be raised or lowered to the desired height.

Rotation Mechanism:

Hydraulic systems enable the rotation of the aerial platform, allowing it to swivel or rotate horizontally. This feature is crucial for positioning workers accurately.

Basket Tilt (Optional):

Aerial platforms with a tilting basket feature use hydraulic cylinders to tilt the basket, providing workers with better access to various angles.

Outriggers or Stabilizers:

Some aerial trucks are equipped with hydraulic outriggers or stabilizers that extend to provide additional stability while the platform is in use.

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:

Aerial trucks often include safety features in the hydraulic system, such as pressure relief valves, emergency lowering systems, 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 aerial platform or a remote control panel.

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