I found this while doing some research for something else, but thought it was pretty cool.

Quickly turn your fork lift into a "portable crane". Caldwell's new Winch Boom combines the reach of a fork lift boom with the precise lifting of a winch, adding value and functionality to your lift truck. The Winch Boom fits standard fork lift trucks and is an economical alternative to an overhead or gantry crane. Available in fixed, telescopic and pivoting telescopic models with winch hook capacities of 2,000 or 2,400 pounds. Standard operation is 110 volt electrical and with optional DC or hydraulic winch operation available on any model.
