A customer in the curtain wall hanging industry was looking for a good way to lift and place his curtain wall into position. The sections could weigh up to 1,500 lbs maximum and would need to be lifted about 10 feet high to get into position. The Reversible Boom Crane, also popular with glaziers, was a great solution. They were working in new construction buildings and were limited to the point floor loads of the crane. We came up with a method to lessen those loads by designing it so that the base of the crane would hydraulically extend in length, spreading out the floor loading as well as reducing the amount of counterweight required to balance the load. The new design not only reduced the overall weight of the crane, but allows it to shorten to a more compact length for maneuverability in tight spaces. This new design feature is now available on units up to 6,000 pounds capacity.
