The optional Adjust-a-Span Kit allows for easy crane width adjustments without drilling the I-Beam and is available for Thrifty Cranes with I-beam lengths of 15′ or less.
All adjustments of several feet to fractions of an inch are made by sliding the entire frame and post assembly on the I-Beam. Set screws in the bracket hold the I-Beam in place.
