Abstract: The present invention provides a locking assembly for a ramp of a lift gate. The locking assembly comprises an elongated locking arm and a spring for spring loading the locking arm. The locking arm is pivotably disposed on a pivot point relative to the ramp. A biasing tension in the spring urges a proximal end of the locking arm to engage with a cam portion of the ramp to maintain the ramp in a selected position. The cam portion has multiple engagement surfaces for individually engaging with the locking arm, wherein selectively engaging the locking arm with each engagement surface of the cam portion maintains the ramp in a corresponding selected position.

Abstract: A locking assembly for a ramp of a lift gate, the locking assembly including: an elongated adjustable locking arm pivotably disposed on a pivot point relative to the ramp, the locking arm including an adjustment mechanism for adjusting a length of the locking arm disposed on a proximal end for engaging a cam portion, where the length of the locking arm can be increased or decreased by adjusting the adjustment mechanism; and a resilient member for spring loading the locking arm, where a biasing tension in the resilient member urges the proximal end of the locking arm to pivotably engage with the cam portion to maintain the ramp in a selected position; and at least one fastener for coupling the locking assembly to a first surface of the ramp.

Abstract: Systems, methods, and devices for correcting a mounting system for mounting a lift gate on a structure, the lift gate having a lift platform supported between a pair of spaced support columns, the correction system including: a first mounting member configured for attachment onto the structure; a first lift gate support column configured for attachment onto the first mounting member; a first correction mechanism configured to couple with a first support block, where the first correction mechanism creates a force between the first lift gate support column and the first mounting member when engaged, resulting in a first corrective gap forming between the first lift gate support column and the first mounting member; and where the resulting corrective gap orients the first lift gate support column to be substantially parallel with a plane parallel to a rear of the structure such that the lift gate platform can be operated.

Abstract: Embodiments of a lift gate include comprise a foldable lift platform including multiple sections that are rotatable relative to one another for folding and unfolding the lift platform, a lifting mechanism for supporting and moving the lift platform, and at least one lift platform locking mechanism coupled to two adjacent sections of the lift platform to lock and unlock two adjacent sections of the lift platform together. The locking mechanism has a locked position and an unlocked position, such that in the locked position the locking mechanism restricts rotation of the two adjacent sections relative to one another.
