Vertically Swinging Shovel Having An Orbital Path Patents (Class 414/566)
  • Patent number: 6674828
    Abstract: A system and method for moving a canister of spent nuclear fuel from a first location, which may be within a nuclear power generation facility to a second location such as a storage cask that is used for short-term or long-term storage of spent nuclear fuel includes a first lifting mechanism for engaging a transfer cask and a second lifting mechanism for engaging and lifting the canister of spent nuclear fuel. Preferably, the method is practiced by first positioning a canister of spent nuclear fuel within the transfer cask and then engaging the transfer cask with the first lifting mechanism. The canister is engaged with the second lifting mechanism. The transfer cask having the canister positioned within is moved to the vicinity of a storage cask, and the canister is lowered from the transfer cask into the storage cask by the second lifting mechanism without disengagement of the first lifting mechanism from the transfer cask.

  • Patent number: 4488849
    Abstract: A power shovel comprises a boom which is supported on an undercarriage and can be lifted and lowered. A hydraulically operated shovel mechanism is mounted at a front end of the boom before pivoting about a horizontal axis. The shoveling mechanism carries a pivotable shovel and at least one cable pulley. A cable hoisting gear engaged with the boom is operable to move the boom. A cable of the cable hoisting gear is trained or reeved on the cable pulley of the shoveling mechanism so that the shoveling mechanism can be moved by the hoisting gear with movement of the boom.
