Material handling plays vital role in any industry. The hoist crane is one of the demonstrated material handling devices. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. In normal operating conditions with rated load and under test conditions with test loads up to 125 percent of rated load, despite this fact many operators and owners of hoists and cranes fear the possible catastrophic damage that can occur if the driving motor of a unit should fail for any reason. This may lead to Loss of life, Damage of goods or property, loss of Production time due to down time of hoist. Hence there is a need of a safety system in advent of failure of the motor that will avoid above damages. One solution to this problem is to feed the power of two motors of equal rating into a planetary gear drive. This system is proposed with view to offer a dual advantage to the existing single motor system, Safety in case one of the motor fails. Dual speed drives so that same device can cater to more than one application.
