A System And Method For Handling Construction Material

A trolley configured to be loaded onto a tilt tray of a truck, the trolley for assisting in the unloading sheets of material from the tilt tray of the tilt truck, the tilt tray having a first end and a second end along a tilt tray elongate axis that is tiltable with respect to the truck, the trolley comprising,

• a support surface onto which the sheets of material can be supported, the support surface having a plurality of rollers over which the sheets of material can roll,
• the trolley further having a trolley elongate axis with a barrier at a loading/unloading end of the elongate axis;
• the trolley having at least a first pair of wheels, a second pair of wheels and an intermediate pair of wheels, wherein the intermediate pair of wheels are located between the first pair of wheels and the second pair of wheels along the trolley elongate axis;
• the trolley configured to be movable relative to the tilt truck, wherein, when the tilt tray is tilted for delivery of a load the trolley is configured to:
• be lowerable along the tilted axis of the tilt tray until at least the second pair of wheels roll off the second end of the tilt tray and contact the ground for rolling along the ground;
• have a first pair of wheels that remain on the tilt tray during delivery;
• allow the barrier at the loading/loading end of the trolley to be removed thereby allowing the sheets of material to roll over the plurality of rollers, off the trolley, and at least partially onto the ground,
• be raised until at least the first wheels roll back onto the tilt tray, leaving only the sheets of material on the ground.

A system for unloading sheets of material from a tilt tray of a tilt truck, the tilt tray comprising:

• a first tilt tray having a first end and a second end;
• and a second tilt tray mounted on top of the first tilt tray and telescopically associated with the first tilt tray, the second tilt tray having:
• a support surface onto which the sheets of material can be supported, the support surface having a plurality of rollers over which the sheets of material can roll;
• a sliding end and a loading/unloading end;
• a barrier at the loading/unloading end;
• arranged on its underside, at least a second pair of wheels at the loading/unloading end;
• wherein, when the tilt tray is tilted,
• the second tilt tray is lowered by telescopically sliding over the first tilt tray, but remaining connected thereto at the sliding end thereof, the second tilt tray sliding until at least the second pair of wheels roll off the second end of the first tilt tray and contact the ground for rolling along the ground;
• the barrier at the loading/loading end of the second tilt tray can be removed to allow the sheets of material to roll over the plurality of rollers, off the second tilt tray, and at least partially onto the ground;
• the second tilt tray is raised back by telescopically sliding back over the first tilt tray, until the second pair of wheels roll back onto the first tilt tray, leaving only the sheets of material on the ground.
