Patent number: 6010171Abstract: Prior lifting probes automatically release from the core of the paper roll as soon as the roll is placed on a surface and the lifting pressure from the cable is released. In some situations that can be undesirable, since some adjustment or juggling of the paper rolls may be required by the crane operator after the roll has first been placed on a surface. It is preferable that the release of the probe can be made remotely at the discretion of the operator to avoid the danger of a worker in close proximity to the cable, lifting probe and paper roll. The present invention provides a power-actuated cylinder to remotely release the lifting probe from the paper roll.Type: GrantFiled: February 3, 1998Date of Patent: January 4, 2000Assignee: John MargiottielloInventor: John Margiottiello

Patent number: 5580113Abstract: A crane/load safety shackle that includes a yoke having a slot that opens along one side edge of the yoke, and a buckle opening for securing the yoke to a crane load line such that the slot opens downwardly. A pin moveably slidably extends laterally across the slot for closing the slot and supporting a load carried by the shackle. A linear actuator and remote control electronics are mounted on the yoke and coupled to the pin for selectively extending the pin across the slot to support the load carried by the shackle, and retracting the pin from the slot so as to release the load. In the event that the load is supported by the pin and thus exerts lateral forces on the pin, the actuator has insufficient power to withdraw the pin from the slot against such lateral forces applied by the load, so that the load will not be inadvertently released.Type: GrantFiled: June 5, 1995Date of Patent: December 3, 1996Assignee: Magnum Construction Company, Inc.Inventors: Thomas E. Pomerville, Ronald L. Williams, Joseph E. Kauffman
