The ratcheting screwdriver comprises a handle with a working end and a reversible ratchet mechanism therein, the ratchet mechanism defining a bore which receives one end of an associated shank coaxially therein. A cup-shaped reversing member is coupled to the handle for limited rotational movement relative thereto and has an annular flange projecting a slight distance radially therebeyond and engageable by a finger and/or thumb of a user's hand which is gripping the handle for shifting the ratchet mechanism between forward ratcheting, reverse ratcheting and non-ratcheting modes. A cup-shaped spinner is fixed to the shank, the reversing member being nested in the spinner with the shank extending through a hole in the reversing member and into the ratchet mechanism, the diameter of the spinner being approximately the same as that of the working end of the handle for easy engagement by the gripping hand of the user to spin the shank relative to the handle. A spacer fixed to the shank cooperates with the spinner to limit axial movement of the reversing member.

An approach ramp for an automotive support platform includes first and second ramp members, the trailing end of the first ramp member being pivotally connected to the leading end of the platform. The second ramp member is both slidably and pivotally movable with respect to the first ramp member. Each ramp member carriers rollers at its leading end for engagement with the floor when the platform is lowered to an access position. In one configuration the ramp members are disposed in overlapping parallel relationship to define a single ramp incline. In a second configuration the second ramp member is extended from the first and is inclined with respect thereto to form a dual-slope ramp incline.
