    摘要： 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.

    摘要： A handle and tiller head plug-in module for a material handling vehicle. The handle having an elongated tiller having an upper portion including at least one steering handgrip member and an upward extending wall surrounding electrical contacts associated with operator control functions. The tiller head plug-in module includes a housing having a downward extending wall surrounding electrical contacts, with the housing supporting a plurality of operator control interface elements, including at least one lift control element, and at least drive control element. The tiller head plug-in module is configured to be removably electrically connected to the handle when the upward extending wall surrounding the electrical contacts of the upper portion of the tiller is plugged into and received by the downward extending wall surrounding the electrical contacts of the housing.
