Latest Patents

Among his latest inventions are two notable patents that showcase his ingenuity and problem-solving skills. The first, titled "Crane Undecking Arrangement," presents a retractable leg structure designed to efficiently undeck a crane's upper from its carrier. This invention features a box member with a circular cross-section and a longitudinal axis affixed to the crane's upper part. Among its innovative components is a beam that rotates relative to the box and an L-shaped leg with a tubular member. The leg is manually swingable to transition between stowed and deployed positions, and includes a locking pin device to secure it in place. Additionally, an extendable jack and hydraulic ram facilitate its operation, providing versatility and ease for crane operators.

Wittman's second recent patent, "Centering Arrangement for Redecking of Crane Upper," addresses the challenge of aligning the swing mechanism during the redecking process. This device incorporates multiple sockets on the carrier, which engage with frustoconical ends on pins that are slidably mounted on the upper. A latch ensures that the pins remain extended, allowing lateral shifting as the support legs are retracted, thus simplifying the redecking operation.
