Which of the following is NOT a type of dump truck?

Tower Crane Truck

• A tower crane is a lifting equipment, not a dump truck. It is used to hoist and move heavy materials vertically and horizontally on construction sites, especially for tall buildings.

• Tower cranes are typically fixed in place or assembled on-site. A tower crane truck may refer to a transport vehicle for crane components, but it is not involved in dumping operations.

• This equipment is designed for precision lifting rather than material hauling or unloading.

Additional Information

• A bottom dump truck has a clamshell-type gate at the bottom of the trailer body. It discharges material downward in a controlled and uniform flow, ideal for road construction and layering aggregate.

• It provides efficient unloading without the need to raise the bed, reducing the risk of overturning.

• Typically used for hauling loose materials like gravel, sand, or coal where linear spreading is needed.

Articulated Dump Truck

• An articulated dump truck has two sections (cab and trailer) connected by a hinge or articulation joint, allowing for better maneuverability on uneven terrain.

• The front section steers the truck, while the rear holds the load. It’s commonly used in mining, earthmoving, and off-road construction projects.

• This design allows it to operate in tight and rough areas where rigid dump trucks may not perform efficiently.

Side or Rear Dump Truck

• These trucks use hydraulic rams to tip the truck bed to the rear or side, unloading the contents quickly.

• Rear dump trucks are common in general construction, while side dump trucks are preferred where space or traffic restricts rear unloading.

• They are used for bulk material transport, such as demolition waste, soil, and construction aggregate.
