  • Patent number: 9714047
    Abstract: The disclosure provides pallet trucks having a selective turning radius. The pallet trucks include load wheel systems having at least two load wheel assemblies below each fork. A forward load wheel assembly is located near the forward end of the fork and a central load wheel assembly is located near the center of a central portion of the fork. A first turning radius is defined by the distance between the forward load wheel assembly and a directionally adjustable rear wheel when the forward load wheel assembly supports the fork. The central load wheel assembly may be selectively deployed to lift and support the fork to yield a second, shorter turning radius defined by the distance between the central load wheel assembly and the directionally adjustable rear wheel.
