1. Field of the Invention
The present invention relates in general to loadcarrying vehicles, and, more particularly, to a novel transformer caddie for transporting and locating transformers and other equipment.
2. Description of the Prior Art
Modern underground residential distribution systems of electric power frequently include small pad-mounted distribution transformers located in unpaved areas behind homes, usually backyards, these areas being generally inaccessible to trucks and cranes typically employed in transporting and locating transformers and other relatively heavy electrical equipment. Periodic replacement of such transformers has, in the past, presented serious problems, particularly when replacement transformers must be moved through gates or other narrow passageways and into hilly terrain. Furthermore, the problems associated with transformer replacement are aggravated by mud and snow conditions.
One device used for transporting such distribution transformers is a small dolly or wheeled platform. However, since such transformers are frequently quite heavy, often weighing on the order of one ton or more, a rather large work crew has been found to be necessary to wheel and set a transformer into place on its pad using this device.
Another known device is a pole-carrying vehicle comprising an inverted U-shaped frame having a winch mounted on its top for suspending a load, the device having a pair of steerable front wheels similar to those found on a wagon. However, this device lacks maneuverability, particularly necessary for positioning a transformer onto its mounting pad. Furthermore, since this device is rather large, its lack of maneuverability prevents easy movement through narrow passageways.
