  • Publication number: 20080107511
    Abstract: A tool for dragging wooden shipping pallets along the ground comprises a wheel-mounted base member that has an elongated handle attached to it. The base member supports a pair of jaw members that is pivotally joined to one another along with a pair of linkages pivotally joined at one end to the base member and at the other ends to the end portions of the jaw members. A tension spring is connected between the pivot points where the linkages join to the end portions of the jaw members to normally urge the jaws to be closed relative to one another. A cable or cord attaches at one end of the pivot joint between the two jaw members and extends along the length of the handle to a pull knob. Tension on the cable or cord acts against the force of the spring to open the jaw members.
