Study Notes
Box Van
- Capacities range from 1.5 tons to 5 tons, including cabin modification.
- Composite construction with a framing and sheet metal panels.
- Joints are covered with aluminum molding.
- Designed for limited movement of the vehicle.
- Features two rear doors hinged to corner pillars, with optional shutters sliding into the body.
- Framing is typically 7/8 inches, covered with steel sheets for a smooth appearance.
Panel Vans
- Light commercial vehicles with a Gross Vehicle Weight (GVW) up to 3.5 tons, popular for tradesmen.
- Steel pressing bodies with large rear doors for easy loading/unloading.
- Primarily of integral construction, often with chassis cab arrangements.
- Types include tipper, drop sides, and box vans.
Rigid Types
-
Six Wheeled:
- Consist of two steering road wheels and either four driving wheels or a combination of driving and free-running wheels on a dead axle.
-
Eight Wheeled:
- Similar driving wheel arrangement to six-wheeled vehicles but equipped with four-wheel steering.
- Steering wheel interlining ensures true rolling motion while negotiating corners.
- Utilizes load weight to enhance the adhesion of the driving wheels.
Articulated Type
- Features a short chassis with integrated engine and transmission, equipped with a strong towing and swiveling attachment.
- Typically has four or six wheels, with some acting as driving wheels.
-
Advantages:
- Greater maneuverability and smaller turning radius due to articulation.
- Trailer can be detached for separate loading/unloading.
-
Disadvantages:
- Limited free movement of the coupling makes it unsuitable for uneven ground.
- Potential instability on side slopes.
Draw Bar Trailers
- Constructed similarly to a four-wheeled rigid vehicle, but lacks its own power unit and transmission.
- Towed and steered by a drawing vehicle through a draw bar connection.
- Commonly paired with four-wheeled rigid vehicles, but can also operate with six and eight-wheeled vehicles.
- Variety of trailer types, including flat platform, sided body, vans, or skeletal designs.
- Size and capacity can reach up to approximately 30.5 tons; larger models require more axles.
- Suspension options include conventional semi-elliptic springs, rubber, or air systems.
- Draw-bar trailers often easier to handle than semi-trailers despite overall combined length.
