Basic Components of a Forklift as Shown in the Diagram
A forklift consists of several interconnected parts, each contributing to the machine's overall performance. The diagram typically illustrates these components divided into structural, hydraulic, electrical, and safety systems.
Structural Components
Structural parts form the framework of the forklift, providing stability and support.
- Mast: The vertical assembly that raises and lowers the load. It can be a simple single mast or a complex three-stage mast for higher lift heights.
- Carriage: The component attached to the mast that holds the forks and moves vertically along it.
- Load Backrest: A safety feature attached to the carriage to prevent loads from falling backward.
- Chassis or Frame: The base structure supporting all other components, ensuring stability during operation.
Hydraulic System Components
Hydraulics are central to the forklift's ability to lift and maneuver loads.
- Hydraulic Cylinders: Actuators that extend and retract to raise or tilt the forks.
- Hydraulic Pump: Generates the hydraulic pressure needed for movement of cylinders.
- Hydraulic Valves: Control the flow of hydraulic fluid to various cylinders and motors.
- Hydraulic Hoses: Convey hydraulic fluid between components.
Power Source Components
Forklifts are powered by various sources, depicted in diagrams for different models.
- Engine: Internal combustion engines (gasoline, diesel, or LPG) or electric motors.
- Battery: For electric forklifts, the diagram shows the battery pack, charging port, and related electrical systems.
Operational Controls
The operator interface is crucial for controlling the forklift.
- Steering Wheel or Levers: For directional control.
- Lift and Tilt Levers: To raise/lower and tilt the forks forward or backward.
- Pedals: Typically include accelerator, brake, and inching pedals for precise operation.
Safety and Additional Features
Safety features are integral parts of the forklift diagram.
- Overhead Guard: Protects the operator from falling objects.
- Emergency Stop Button: Shuts down the machine immediately in case of emergency.
- Lights and Alarms: Indicate operational status and alert nearby personnel.
