Abstract
A maintenance/construction cart that facilitates wall and ceiling access while isolating the interior of the cart from the surrounding environment. The cart is configured such that its height can be easily adjusted by an operator to provide access to ceilings of different heights while maintaining the seal between the interior of the cart and the surrounding environment while structurally supporting a ladder leaning against a surface of the cart. In some embodiments, the cart includes an air filtration unit.
Claims20
A maintenance cart comprising:
- a lower structure with a floor, an upper portion, and a plurality of sides that extend between the upper portion and the floor;
- an upper structure disposed above the upper portion of the lower structure, the upper structure comprising a plurality of structural members, each structural member of the plurality of structural members connecting the upper structure to the lower structure, wherein at least two of the structural members move the upper structure relative to the lower structure between a stowed position and a raised position;
- and
- a ladder support bracket attached to an interior of the maintenance cart, wherein the ladder support bracket is moveable relative to the lower structure, and wherein the ladder support bracket structurally supports a ladder,
- wherein the maintenance cart comprises a single interior workspace defined by both the lower structure and the upper structure:
- (i) when the upper structure is in the stowed position;
- and
- (ii) when the upper structure is in the raised position.
