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, wherein the first end is connected to the bottom of the frame, and the second end is close to the ladder. 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 makes the stopper contact one of the wheels. Whereby, when an operator steps on the ladder of the picking ladder cart, the lowest step drives the stopper to abut against and stop the wheels, which increases the working efficiency. | 06-09-2016 |
