Abstract
A forklift linkage system () for movement has a levelling carriage assembly () movably contained within a channel assembly (). A main long link pivotally connects to the levelling carriage assembly () at a first pivot point () and a fork carriage assembly () at a second pivot point (). A short link () pivotally connects near a midpoint () of the main long link () at a third pivot point () and at a fixed pivot point () relative to the channel (), near a vertical offset position from the pivot point of the main long link () to the levelling carriage assembly () at a fourth pivot point (). A levelling link () pivotally connects to the levelling carriage assembly () at a fifth pivot point () and at the opposite end to a fork carriage assembly () at a sixth pivot point, such that the travel path of the second pivot point () connecting the main long link () to the fork carriage assembly () remains substantially perpendicular to the channel () when the linkage system () is moved between retracted and extended positions. The angle through the second pivot point () connects the main long link () to the fork carriage assembly (). The sixth pivot point () connects the levelling link () to the fork carriage assembly () substantially constant in relation to the channel () when the linkage system () is moved between retracted and extended positions.
