Picking ladder cart

摘要

A picking ladder cart with a synchronized brake is provided, which includes a frame, a plurality of wheels, a ladder, and a stopper. The ladder is pivotally connected to a side of the frame, wherein the ladder is pivotally movable between a first position and a second position. The ladder includes two side rails and a plurality of steps, which are connected between the two side rails. The stopper has a first end and, a second end. When the ladder is moved to the second position, one of the plurality of steps, which is arranged at the lowest position among the steps, abuts against the second end of the stopper, which causes the stopper to contact one of the wheels. When an operator steps on the ladder of the picking ladder cart, the lowest step drives the stopper to abut against one of the wheels.

1. A picking ladder cart, comprising:
a frame; a plurality of wheels installed at a bottom of the frame, which allows the picking ladder cart to be moved on a flat surface; a ladder pivotally connected to a side of the frame, wherein the ladder is pivotally movable between a first position and a second position, and comprises of two side rails and a plurality of steps which are connected between the two side rails; the two side rails are adjacent to the frame when the ladder is moved to the first position; the two side rails are moved away from the frame when the ladder is moved to the second position; one of the plurality of steps, which is arranged at a lowest location among the plurality of steps is defined as a lowest step closest to the plurality of wheels; a stopper provided at the bottom of the frame, which has a first end and a second end, wherein the first end is connected to the bottom of the frame, and the second end is adjacent to the ladder; wherein the lowest step abuts against the second end of the stopper when the ladder is moved to the second position, which causes a middle part of the stopper to contact one of the plurality of wheels; and the lowest step remains abutting against the second end when the ladder is in the second position, which prevents movement of the picking ladder cart along the flat surface.
