  • Storage assembly for battery energizing switches of electric machines
    Patent number: 11525240
    Abstract: A storage assembly for switches couplable to batteries of an electric machine to energize the batteries. The storage assembly includes a container defining a cavity to store the switches, a lid movable between a closed state and an open state with respect to the container to respectively close and open the cavity, and a lock out tag out (LOTO) device. The container is configured to be grasped between a pair of arms of a handrail that swings with respect to a walkway platform of a power compartment of the electric machine. The LOTO device is interchangeable with the switches to selectively be received in the cavity in place of the switches when the switches are coupled to the batteries, and be coupled to the batteries in place of the switches to lock out and keep the batteries from energizing when the switches are received in the cavity.
