Load positioning assembly and method
First Claim
1. A load positioning assembly for a material handling vehicle having a frame, comprising:
- a load carrying device having a load carrying portion mounted on the frame and movable in directions along an elevationally oriented axis;
a carrier having a support portion and being connected to and movable with the load carrying portion;
a pilot member freely carried on the support portion of the carrier and being elevationally movable with the load carrying portion between first and second preselected elevationally spaced apart positions relative to the frame; and
first means for engaging the pilot member, moving said pilot member in directions transverse to the axis in response to movement of the pilot member towards the first elevational position, and for maintaining the pilot member at a first preselected transverse location relative to the axis in response to being at the first elevational position.

Abstract
A load positioning assembly and method for locating and maintaining a load supporting device on a material handling vehicle, includes a load carrying device mounted on a frame and a load carrying portion elevationally movable along an elevationally oriented axis. A pilot member which is freely movably supported on a carrier connected to the load carrying portion is elevationally movable with the load carrying portion between first and second preselected elevationally spaced apart positions relative to the frame. A first engaging device moves the pilot member in directions transverse to the axis in response to movement of the pilot member toward the first elevational position and maintains the pilot member at a first preselected transverse location relative to the axis and the load supporting device at a preselected transverse location at the first elevational position of the load carrying portion. The load positioning assembly is particularly suited for use on an SGV.

18. A method for positioning a load supporting device on a frame of a material handling vehicle including a load carrying portion and a pilot member, comprising the steps of:
-
moving the load carrying portion and the pilot member in an elevational direction toward a first elevational position and engaging the pilot member with the load supporting device; guiding the pilot member in directions transverse the direction of elevational movement and into a bore in the load supporting device; engaging the load supporting device and elevating the load supporting device for free movement in directions transverse to the direction of elevational movement of the load carrying portion; and engaging the pilot member and urging the pilot member to a first preselected transverse location relative to the direction of elevational movement of the load carrying portion and the load supporting device to a preselected transverse location relative to the frame. - View Dependent Claims (19)
