Mobile elevating work platform
There is provided a mobile height-adjustable platform that includes a chassis with ground engaging wheels. A mast is pivotally connected to the chassis and is movable between a transport position where the mast is parallel to and disposed over the chassis, and an operative position where the mast is perpendicular to the chassis and extends upwards. A conveyor moves along the mast and a work platform is pivotally connected to the conveyer. The work platform is movable between a transport position where the platform is parallel to the mast and an operating position where the platform is perpendicular to the mast.
1. A mobile height-adjustable platform, comprising:
a chassis having ground engaging wheels;
a mast pivotally connected toward an outer perimeter of the chassis, the mast having a transport position parallel to and disposed over the chassis and an operating position perpendicular to the chassis and extending upward;
a conveyor that moves along the mast;
a work platform connected to the conveyor by a pivotal connection, the pivotal connection moving the platform between a transport position parallel to the mast and an operating position perpendicular to the mast and extending outward from the outer perimeter of the chassis; and
a height adjustable staircase having a first end connected to move with the conveyor along the mast and a second end movably mounted adjacent to the chassis, the second end moving toward the mast as the conveyor is raised and moving away from the mast as the conveyor is lowered such that the height adjustable staircase is underlying the mast when the mast is in the transport position.
2. The mobile height-adjustable platform of claim 1 , wherein, in the transport position, an upper surface of the work platform is adjacent to the mast.
3. The mobile height-adjustable platform of claim 2 , further comprising a safety railing along at least opposed sides of the work platform, the safety railing being separated by a width that is greater than a width of the mast, and the mast nesting within the safety railing in the transport position.
4. The mobile height-adjustable platform of claim 3 , further comprising collapsible railing sections attached to the work platform or the safety railing.
5. The mobile height-adjustable platform of claim 1 , wherein the mast is pivotally connected to a rear edge of the chassis.
