Abstract

A lockout unit coupled to a gate to provide selective access to an electrical machine is provided. The lockout unit includes a stationary bracket, an arm, and a removable bracket. The stationary bracket includes a first aperture defined therein, and the arm includes a second aperture defined therein. The arm is selectively movable between an open position in which the arm is spaced from the stationary bracket, and a closed position in which the second aperture is substantially concentrically-aligned with the first aperture to receive a locking device therethrough. The removable bracket is selectively coupleable to the arm when the arm is in the closed position. The removable bracket includes a third aperture defined therein that is selectively aligned with one of the first aperture and the second aperture to receive the locking device therethrough when the removable bracket is coupled to the arm.

First claim

What is claimed is:

1. A method for preventing access through a gate using a lockout unit coupled to the gate, the lockout unit including a stationary bracket including a first aperture defined therein, an arm including a second aperture defined therein, and a removable bracket including a third aperture defined therein, said method comprising:
positioning the arm in a closed position in which the lockout unit prevents opening of the gate;
coupling the removable bracket to at least one of the arm and the stationary bracket when the arm is in the closed position to align the third aperture with one of the first aperture and the second aperture;
inserting a portion of a locking device through the third aperture and the aligned one of the first aperture and the second aperture to secure the arm in the closed position;
moving the arm to an open position such that the second aperture is substantially concentrically-aligned with the first aperture, wherein moving the arm to the open position switches an electrical machine associated with the gate from a normal operating mode to a maintenance mode; and
inserting the portion of the locking device through the first aperture and the second aperture such that the locking device secures the arm in the open position.

2. The method in accordance with claim 1 , wherein coupling the removable bracket to at least one of the arm and the stationary bracket comprises coupling at least one non-removable pin of the removable bracket to one of the arm and the stationary bracket.

3. The method in accordance with claim 1 , wherein coupling the removable bracket to at least one of the arm and the stationary bracket comprises inserting one of the stationary bracket and the arm in a retaining opening defined by a retaining member of the removable bracket.
