Abstract
Abstract An industrial pallet or stillage truck has a body portion, two hydraulic rams for raising a root portion of a load carrying portion, and a linkage having ground engaging members for raising and lowering the end of the load carrying portion remote from the root portion. The rams each have a standing part mounted on the body portion and a movable part connected to the load carrying portion. The linkage includes two levers each of which is pivotally connected at its fulcrum to the root portion of the load carrying portion and also pivotally connected to the standing part of one of the rams. At least one of the rams has its standing part adjustably mounted on the body portion whereby longitudinal movement of the standing part moves the respective lever and adjusts the position of the associated ground engaging member relative to the load carrying portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
223 words
An industrial pallet or stillage truck comprising a body portion, a load carrying portion mounted for up and down movement relatively to the body portion, two hydraulic rams for raising a root portion of the load carrying portion, and a linkage operated by movement of the root portion relatively to the body portion and including ground engaging members for raising and lowering the end of the load carrying portion remote from the root portion, in unison with the root portion, each ram comprising a standing part connected to the body portion and a movable part connected to the load carrying portion, and the linkage comprising two operative levers each pivotally connected at its fulcrum to said root portion and also being pivotally connected directly to the lower end of said standing part of one of the rams, whereby up and down movement of the root portion imparts pivoting movement to the levers to operate said linkage, and means for mounting the standing part of at least one of said rams to said body portion so that it is adjustable longitudinally with respect to said body portion, whereby longitudinal adjustment of the standing part of said one ram moves the lever connected to that standing part and thereby adjusts the position of the associated ground engaging member with respect to the load carrying portion.
Claim 2
Dependent Claim
223 words
An industrial pallet or stillage truck comprising a body portion, a load carrying portion mounted for up and down movement relatively to the body portion, two hydraulic rams for raising a root portion of the load carrying portion, and a linkage operated by movement of the root portion relatively to the body portion and including ground engaging members for raising and lowering the end of the load carrying portion remote from the root portion, in unison with the root portion, each ram comprising a standing part connected to the body portion and a movable part connected to the load carrying portion, and the linkage comprising two operative levers each pivotally connected at its fulcrum to said root portion and also being pivotally connected directly to the lower end of said standing part of one of the rams, whereby up and down movement of the root portion imparts pivoting movement to the levers to operate said linkage, and means for mounting the standing part of at least one of said rams to said body portion so that it is adjustable longitudinally with respect to said body portion, whereby longitudinal adjustment of the standing part of said one ram moves the lever connected to that standing part and thereby adjusts the position of the associated ground engaging member with respect to the load carrying portion.
Claim 3
Dependent Claim
30 words
A truck as claimed in claim 1, wherein one cylinder of said one ram constitutes the standing part thereof and the piston of said one ram constitutes the movable part.
Claim 4
Dependent Claim
21 words
A truck as claimed in claim 1, wherein the rams extend in an up and down direction on the body portion.
Claim 5
Dependent Claim
38 words
A truck as claimed in claim 1 wherein means are provided for mounting the standing part of each of said rams to said body portion so that they are individually adjustable longitudinally with respect to said body portion.
Claim 6
Dependent Claim
76 words
A truck as claimed in claim 1, wherein the standing part of said one ram comprises first and second portions in threaded engagement with one another, said first portion being rotatable and said second portion being non-rotatable so that rotation of the first portion causes the second portion to move longitudinally, the lever associated with said one ram being connected to said second portion so that the longitudinal movement of said second portion moves the lever.
Claim 7
Dependent Claim
23 words
A truck as claimed in claim 5, wherein releasable detent means are provided to retain the first portion in a required rotational position.
