Abstract
A gin or lifting mechanism is provided for relatively heavy electrical equipment, such as transformers and the like. The gin is removably mounted on a pole above a cluster rack which is to receive the electrical equipment. The gin transfers the load of the equipment to the pole along a vertical central axis of the pole at an intermediate position between its upper and lower ends. The gin has an adjustable length support arm which is particularly suitable for movement of relatively heavy loads, especially in areas inaccessible to load lifting vehicles.
