Latest Patents

One of his latest patents is the Twistlock Operator. This invention features a drive mechanism with a fixed axis and an angularly displaceable twistlock. The design includes a first actuator connected to the drive mechanism, allowing for rotation, and a second actuator linked to the twistlock. Each actuator is rectangularly shaped with arcuate side bearing surfaces that have equal radii of curvature. A pivotal tube connects the actuators, ensuring they maintain a driving connection even when the twistlock pivots.

Another significant patent is the Gantry Crane. This invention consists of a pair of spaced, parallel rectangular side frames equipped with top and bottom members, as well as front and rear vertical members. The design includes a front cross beam rigidly connected to the side frames and a rear cross beam that is pivotally connected. The gantry crane is engineered to traverse uneven ground while maintaining ground contact through its drive wheels, which absorb torsional stress during operation.
