Abstract
A steerable and rackable electrical apparatus system including a wheeled rackable electrical apparatus (10). The system allows steerable movement of an unracked apparatus (10) that has been removed from a switchgear cabinet. The system includes a device (20) with a lifting bracket (22) selectively attachable and detachable from the electrical apparatus (10); and a steerable, wheeled, self-supporting lifting device (30) for lifting a portion of the electrical apparatus (10) to a lifted position and for supporting weight of the lifted apparatus (10) without operator lifting effort. The lifting device (30) may be screw jack with a castered wheel (38) that is coupled to the lifting bracket (22).
Claims16
A steerable, rackable electrical apparatus system comprising:
- a wheeled rackable electrical apparatus;
- a lifting bracket selectively attachable and detachable from the electrical apparatus;
- and
- a steerable, wheeled, self-supporting means for lifting a portion of the electrical apparatus to a lifted position and for supporting weight of the lifted apparatus without operator lifting effort, coupled to the lifting bracket.
A steering device for a wheeled, rackable electrical apparatus comprising:
- a lifting bracket selectively attachable and detachable from an electrical apparatus having at least two fixed position wheels;
- and
- a steerable, wheeled, screw jack coupled to the lifting bracket for lifting a portion of the electrical apparatus to a lifted position and for supporting weight of the lifted apparatus without operator lifting effort;
- the single steering device in cooperation with the electrical apparatus wheels allowing steering of the apparatus when in the lifted position.
A steering device for a wheeled, rackable electrical apparatus comprising:
- a steerable, wheeled, screw jack for lifting a portion of an electrical apparatus to a lifted position and for supporting weight of the lifted apparatus without operator lifting effort;
- and
- a lifting bracket having a generally vertically aligned central portion attached to the jack, a generally horizontally aligned first flange projecting generally normal from the central portion and a second flange projecting forwardly and downwardly from the central portion, the second flange including a lip projecting therefrom for selective attachment and detachment with the electrical apparatus.
