## Claims

### Claim 1

A carriage for a forklift truck comprising:
a frame;
a first sideplate secured to the frame, the first sideplate comprising an interior surface and an exterior surface opposite the interior surface, an upper portion, an intermediate portion, and a lower portion with a guide attached to the exterior surface of the upper portion and a guide attached to the exterior surface of the lower portion; and
a second sideplate secured to the frame, the second sideplate comprising an interior surface and an exterior surface opposite the interior surface, an upper portion, an intermediate portion, and a lower portion with a guide attached to the exterior surface of the upper portion and a guide attached to the exterior surface of the lower portion;
wherein the first and second sideplates are constructed and shaped such that when the first and second sideplates are secured to the frame a first distance between the interior surfaces of the intermediate portions of the first and second sideplates is greater than a second distance between the interior surfaces of the upper portions of the first and second sideplates;
wherein the first and second sideplates are constructed and shaped such that when the guides attached to the upper portions and lower portions of the first and second sideplates are located within vertical channels of a mast (i) the upper portions of the first and second sideplates are outside such vertical channels of a mast, (ii) the intermediate portions of the first and second sideplates are within such vertical channels of a mast, and (iii) the lower portions of the first and second sideplates are outside such vertical channels of a mast.

a width of the intermediate portion of the first sideplate is less than a width of a channel of a mast that is configured to bear the carriage; and
a width of the intermediate portion of the second sideplate is less than a width of another channel of the mast that is configured to bear the carriage.

### Claim 4 (depends on 1)

A carriage for a forklift truck according to claim 1, wherein:
the first and second sideplates are constructed and shaped such that when the first and second sideplates are secured to the frame the first distance between the intermediate portions of the first and second sideplates is greater than a third distance between the lower portions of the first and second sideplates.

### Claim 5 (depends on 4)
