- Grapple truck
Grapple truck is a term used to described a truck that has a grapple loader mounted to its frame which is used for loading and sometimes hauling
bulky waste . A grapple loader is defined by ANSI Z245.1 as:“a hydro-mechanical device able to rotate on an axis with a grapple or bucket attached at the end of the boom, which is intended for the collection of waste that due to size and/or weight is impractical to containerize.”
Grapple trucks are commonly used by municipal sanitation or public works departments, and by waste collection companies. There are 6 bulky waste collection systems in which grapple trucks are used:Loader and body system
Grapple truck is configured to include a dump body. A single operator loads, hauls, and dumps trash.
Rear steer system
A grapple loader is mounted on the rear of a short frame chassis with an operator's cab mounted between loader and chassis cab. Loader is operated from this cab, and all driving controls are also routed to the operator's cab enabling the "rear steer" unit to drive backwards along the route and load into separate haul trucks.
Rolloff system
Grapple loader is mounted behind truck cab. Cable roll off is mounted behind grapple. Grapple loads in to roll off boxes. When box is full it is dropped at a staging area and an empty box is rolled on. Boxes are transported between staging area and landfill by a shuttle truck.
Rear mounted loader and haul truck system
Grapple loader is mounted on rear of short frame chassis. Grapple truck loads into separate haul trucks which travel back and forth between loading unit and landfill.
Rear mounted loader and trailer system
The Grapple loader is mounted on rear of a short frame chassis, with a trailer hauled behind. The trailer is loaded, then exchanged for an empty trailer when it's full. An additional truck is used to shuttle trailers between landfill and loading vehicle.
Transfer system
The Grapple truck is mounted with a dump body on a chassis. Grapple truck loads into dump body or into separate haul trucks. When grapple truck dump body is full, trash is transferred into another haul vehicle.
