  • Patent number: 7934757
    Abstract: The hydraulic crane-mounted remotely-controlled lifting device (10) includes a housing (26) having hydraulically-operated, grasping members (16), (44, 46) that will permit the removal of limbs from the trunk of the tree without having a climber to move out on each limb to secure the lifting device (10). The device (10) can be easily attached and detached from the end of the crane's cable (12) and requires no other physical connection to the crane other than the cable. The device (10) is self-contained in that all hydraulic mechanisms (30, 32), including an electric power source (34) for operating the hydraulic mechanisms, are enclosed in the housing (26). A wireless control device (22) permits the crane operator to position the pair of grasping members around the designated tree limb from a remote position.

  • Patent number: 7837245
    Abstract: A hollow crane spreader beam incorporates at least one radio-controlled load-release assemblies. Each assembly includes a slidable bolt that is coupled to the plunger of an electric-motor-driven, radio-controlled door lock unit that is installed within the beam. When in a first position, taken in response to application of first polarity voltage to the door lock motor, the bolt traps a free end of a load-supporting chain or cable between a pair of eye blocks, each having an aperture through which the bolt slides. When in a second position, taken in response to application of a second polarity voltage, the bolt releases the free end. The spreader beam also incorporates a radio receiver/controller unit and a battery that is coupled to both the radio receiver/controller unit and the multiple door lock units.

  • Patent number: 6010171
    Abstract: 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.

  • Patent number: 5580113
    Abstract: 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.
