Frequently in material handling, a high degree of stability is required in transporting a load at or between work stations.  This can be accomplished in several ways; by using variable frequency drives that accelerate and decelerate gently; by using a hoist with multiple lift points to a lifting bar or attachment; even, as in this case, by adding sliding vertical braces to minimize sway.

     The bundle handling attachment seen here is stabilized by its low center of gravity suspended by a wire rope at each of the four corners of its upper frame.

     This crane utilizes a telescoping scissors frame to provide extremely good stability for placing the load inside a series of ovens.  The load is raised and lowered by the hoist using wire ropes while the scissors mechanism provides lateral stability.
