Abstract
An outrigger assembly having a mounting portion mountable directly to a dump trailer suspension system. In one embodiment, the mounting portion is mounted directly to leaf springs of a suspension system. Two stabilizing arms are pivotably attached to the mounting portion. A driving mechanism is connected to the stabilizing arm and configured to move the stabilizing arms between an inward, stowed position, and an extended, stabilized position. The stabilizing arms being shaped and sized to engage the ground outboard of the dump trailer wheel base to increase the effective width of the dump trailer's support base, thereby stabilizing the dump trailer from tipping.
Claims12
A stabilizing outrigger assembly and dump trailer, comprising:
- a dump trailer having a suspension system and a frame;
- a mounting portion attached to the dump trailer's suspension system independent of the frame;
- a stabilizing arm pivotally attached to the mounting portion;
- and
- a driving mechanism connected to the stabilizing arm and being moveable relative to the mounting portion to move the stabilizing arm between a stowed position and a deployed position with a distal portion of the stabilizing arm substantially adjacent to the ground, the driving mechanism being configured to releasably secure the stabilizing arm in the deployed position while the dump trailer is engaged in the dumping operation.
The outrigger assembly of clam 1, further comprising a second stabilizing arm pivotally attached to the mounting portion, and a second driving mechanism connected to the second stabilizing arm and being movable to pivot the second stabilizing arm relative to the mounting portion.
A stabilizing outrigger assembly for use with a dump trailer having a suspension system, comprising:
- a mounting portion attachable to the dump trailer's suspension system;
- a stabilizing arm pivotally attached to the mounting portion;
- and
- a driving mechanism connected to the stabilizing arm and being moveable relative to the mounting portion to move the stabilizing arm between a stowed position and a deployed position with a distal portion of the stabilizing arm substantially adjacent to the ground, the driving mechanism being configured to releasably secure the stabilizing arm in the deployed position while the dump trailer is engaged in the dumping operation;
- wherein the mounting portion is releasably attachable directly to the dump trailer's suspension system.
A stabilizing outrigger assembly for use with a dump trailer having a suspension system, comprising:
- a mounting portion attachable to the dump trailer's suspension system;
- a stabilizing arm pivotally attached to the mounting portion;
- and
- a driving mechanism connected to the stabilizing arm and being moveable relative to the mounting portion to move the stabilizing arm between a stowed position and a deployed position with a distal portion of the stabilizing arm substantially adjacent to the ground, the driving mechanism being configured to releasably secure the stabilizing arm in the deployed position while the dump trailer is engaged in the dumping operation;
- wherein the mounting portion includes a bottom plate positionable below the suspension system, a top plate positionable above the suspension system, and securing member interconnecting the top and bottom plates with the suspension system sandwiched between the top and bottom plates.
