Abstract
A material handling system for engaging and lifting transformer coils. Four leg assemblies are provided around a transformer. The leg assemblies have extensible plates which extend underneath the transformer. The leg assemblies are secured by chains to an overhead cruciform spacer which is coupled to a crane or other device. The leg assemblies may be bound together by straps to prevent movement of the leg assemblies relative to one another. For smaller or larger transformers, a lesser or greater number of leg assemblies may be used.
