摘要： An apparatus includes a platform having a first end and a second end and a handle. The apparatus includes a first leg assembly rotatably attached to the platform in proximity to the first end. The apparatus includes a second leg assembly attentively attached to the platform in proximity to the second end. When the first and second leg assemblies are essentially perpendicular to the platform, the apparatus is in a use state and the user is able to stand on the platform and be supported by the first and second leg assemblies. When the apparatus is in the use state, the user is able to pick up the apparatus by the handle with only one of the hands without tipping the apparatus. A method for a user with hands to stand on an apparatus. A work platform having legs which are coplanar with the platform when the legs are in a closed position. The work platform having a hinge bracket with a tab against which a leg contacts and is stopped when the leg is in an open position.

摘要： The disclosure relates to a work over platform apparatus and method for use with trenches and cellars. The apparatus includes two platform portions joined at the center by a set of hinges. The set of hinges is divided to allow for cutouts in each of the platform portions. When deployed the cutout portions are aligned to form an opening that allows work personnel to access the cellar through the work over platform. The work over platform may be collapsed along its hinges for compact transport to and from a work site. The method includes deploying, using, and collapsing the apparatus.
