Abstract: A ladder assembly for a work vehicle comprises a deck affixed horizontally just below an entry door of the cab. A yoke is pivotally joined to a support member of the deck for rotation about a vertical axis below the deck surface. The yoke has a pair of arms pivotally joined to an upper end of a ladder structure for allowing rotation of the ladder about a horizontal axis. A turnbuckle is coupled between the support structure of the deck and one stringer of the ladder while a mechanical actuator is operatively coupled to the ladder's other stringer and to an arm of the yoke to which the other stringer is attached. Operation of the mechanical actuator moves the ladder reciprocally between a use position and stowed position where the stowed position is parallel to and immediately below the deck.

Abstract: A platform unit used with a scaffolding structure includes a worker's platform and a ladder for climbing onto the worker's platform. The platform unit includes a first tipping prevention member adapted to interact with a substantially horizontal longitudinally extending first support member, and a second tipping prevention member adapted to interact from below with a substantially horizontal longitudinally extending second support member. The second support member is vertically spaced apart from the first support member. At least a part of at least one of the first and second tipping prevention members is vertically adjustable for enabling attachment and detachment of the platform unit to the scaffolding structure. At least three rollers support the platform unit, with each of the rollers adapted to rest against either the first support member or the second support member, such that the platform unit is rollingly movable in the longitudinal direction.

Abstract: A lift-up safety grab post mechanism for rooftop hatchway curbs having a mounting bracket on a hatchway curb and having an elongate opening having a pivot bolt for upward and downward grab post movement. A lift-up grab post has a pivot opening receiving the pivot bolt and having a stop member fixed thereto. The lift-up grab post is rotationally moveable between an upstanding position and a horizontal position relative to the roof hatchway curb. The mounting bracket defines a receiver seat and further defines a stop shoulder adjacent the receiver seat that prevents rotational movement of the grab post until the grab post has been raised from said receiver seat to a position above the stop shoulder.
