Abstract:
1. A portable motorized racking tool for removing or installing electrical components for electrical equipment surrounded by a metal surface by an operator outside an arc flash hazard boundary, wherein the portable motorized racking tool comprises: a. a frame comprising: b. a motor arm extending perpendicular from the bar, wherein the motor arm is supported by a first gusset and a second gusset; c. a locking device disposed on the motor arm configured to operatively engage a spring to apply pressure to maintain a connection between a coupling and the electrical equipment to be operated upon; d. a sliding motor bracket connected to the motor arm configured to maintain the coupling with the electrical equipment at a predetermined distance from the frame; e. a first magnetic support slidably attached to the first side support; f. at least one removable magnetically shielding magnet housing slidingly connected to the first magnetic support and over the first side support; g. an extendable and retractable magnet having a magnet handle disposed within each removable magnetically shielding magnet housing, wherein the extendable and retractable magnet is configured to magnetically connect the frame flush to the metal surface surrounding the electrical equipment; h. a motor with a gear box, wherein the motor is in communication with a motor control housing through a signal and power cord, and wherein the motor control housing has an interface plug in communication with a remote switch operator having a remote control device for controlling the remote switch operator for receiving power and control signals therefrom; i. a rotatable shaft with a shaft keyway and a key connected to the gear box, wherein the gear box has a shaft housing with a gear box keyway, wherein the rotatable shaft is engaged with the shaft housing, and wherein the key is engaged with the gear box keyway; j. a torque limiting clutch connected to the rotatable shaft and the coupling; and k. an alignment tool engaged with the rotatable shaft, wherein the alignment tool is configured to rotate the coupling to align the coupling with the electrical equipment.
