1. A cask transporter for transporting nuclear waste casks, comprising:

  • a pair of substantially parallel, spaced treads;

    a motor for powering said treads;

    a platform carried by said treads defining an open-ended area between said treads for receiving a cask to be transported;

    a pair of substantially vertical spaced extendable booms extending upwardly from said platform on opposite sides of said open-ended area;

    a beam extending substantially horizontally across the upper ends of said extendable booms and raisable with said extendable booms;

    one or more couplers carried on said beam for connecting said beam to a cask to be transported so that the cask is raised when said extendable booms are extended to raise said beam; and

    a restraint coupled to said platform and engageable with the cask for restraining the cask against swinging movement relative to said cask transporter when the cask is being transported by said cask transporter;

    wherein each of said extendable booms is extended by means of applied hydraulic pressure and wherein each of said extendable booms includes an automatic brake responsive to the loss of applied hydraulic fluid pressure for locking each of said extendable booms against unintended retraction in the event of a loss of applied hydraulic fluid pressure.
