A work platform system having a first work platform. The first work platform having a first hook assembly and a first latch assembly. The system having a second work platform. The second work platform having a second hook assembly and a second latch assembly. The first work platform locked to the second work platform through the first hook assembly engaging with the second latch assembly and the first hook assembly in the use position. A method for using a work platform system. A method for producing a work platform.

An unlocking structure of workbench ladder includes a platform and two ladders hinged to the two ends of the platform; wherein, the ladder includes an unlocking structure relative to the hinged joint of the platform, and the unlocking structure includes an operating button, rotating lock tongue and a first elastic element; the rotating lock tongue is arranged in the column and the upper end is a locking hook which is locked and located in the locking plate at the bottom of the platform; the first elastic element acts between the rotating lock tongue and the column driving and positioning the locking hook toward the locking plate to lock the ladder and the platform; the operating button acts on the rotating lock tongue to overcome the first elastic element and drive the locking hook to move in a direction opposite to the locking plate, unlocking the ladder and the platform.

A plank scaffold system and, more particularly, to a ladder-based vertically-adjustable plank scaffold system. The system may have a pair of ladders, a wall standoff mounted at the top of each of the ladders, a crane support mounted at the top of each of the ladders, a vertical guide bar and roller system to keep it from swinging on the cables, and a horizontal platform suspended on cables below the crane supports, the platform having a pair of cable winches mounted thereon for varying the elevation of the platform. Instead of ladders, tower scaffolds or stage towers may be used on each side to support the vertically-adjustable plank.

A lightweight, multi-function scaffold includes an adjustable height platform that slidably mounts between two ladder frames and a plurality of outriggers to increase stability. The outriggers attach to the ladder frames of the scaffold and extend beyond an end of the scaffold in the longitudinal direction to increase the maximum base width. Increasing the maximum base width increases stability in the longitudinal dimension and reduces the risk of tipping the scaffold end over end when a user climbs the ladder frame to access the platform.
