  • Patent number: 8336913
    Abstract: A steering device for decreasing a turning radius of a pallet jack is disclosed. The steering device comprises a first portion fixedly connected to the pallet jack between a main wheel and the extensible roller thereof. A second portion pivotally attaches to the first portion. A spring disposed within the first portion urges the second portion to remain in a selected position. A wheel disposes within the second portion. Positioning the pallet jack towards the lowered position, the wheel engages the ground causing the extensible roller to disengage the ground whereupon the main wheel and the wheel define a second turning radius which is lesser than the first turning radius. Upon the wheel contacting a lower cross member of a pallet, the second portion is urged against the biasing force of the spring to pivot relatively upwards and over the lower cross member.

  • Patent number: 7475887
    Abstract: A pallet jack having first and second turn radii includes a support frame having a first end and a second end. The support frame is positionable between a raised position and a lowered position. A main wheel connects to the support frame proximate the first end while a first extensible wheel connects to the support frame proximate the second end. The distance between the main wheel and the extensible wheel define the first turn radius when the support frame is in the raised position. A ground engaging device attaches to the support frame between the main wheel and the first extensible wheel. Positioning the support frame towards the lowered position, the ground engageable device engages the ground and the extensible wheel disengages the ground. The second turn radius is thereby defined by the distance between the main wheel and the ground engaging device, which is less than the first turn radius.

  • Patent number: 7462009
    Abstract: A hand-truck for supporting and transporting the load placed thereon includes a stowable handle. The stowable handle is positionable between a stowed position, a locked position and an infinite number of positions therebetween. The handle is accessible by a user at each position. The hand-truck can transport a load by hand and is accessible to be lifted by a forklift from any side.

  • Patent number: 7427075
    Abstract: A steering device for decreasing a turning radius of a pallet jack includes a ground engaging member connected to a support member of the pallet jack between a main wheel and an extensible wheel. The load supporting member of the pallet jack is positionable between a raised position and a lowered position. A first turning radius of the pallet jack is defined by the distance between the main wheel and the extensible wheel. While the extensible wheel engages the ground when the support frame is positioned towards the raised position, positioning the support member towards the lowered position engages the ground engageable member with the ground causing the extensible wheel to disengage the ground. The main wheel and the ground engageable member then define a second turning radius which is less than the first turning radius.
