Abstract
A heat exchanger tube bundle extractor capable of being used either suspended from a crane or while mounted onto a rigid extendible boom. The extractor features brackets for attaching the extractor to cables suspended from a crane. The extractor can also be mounted onto an extendible boom having an articulated head. When desired, the bundle extractor can be used while mounted onto the boom. If crane operations are preferred, the extractor can be readily detached from the boom and suspended from a crane at much higher elevations.
