Chapter 4 DRIVE UNIT
NOTE:
A minimum drive opening of 1980mm [78”] is necessary to maneuver the drive
unit. (See Page 4, Figure 4)
IMPORTANT:
Do not damage piston rods. Do not lift drive unit by any of the hydraulic
components.
Align and level drive unit.
Drive unit is butted against channel at rear of fifth-wheel tunnel. (See detail E)
Center the drive unit in the drive gap. The 25mm x 25mm [1” x 1”] tubing should extend
50mm [2”] past the formed cross sills at each end of the drive unit. The cross-drive
should be parallel to container cross-members.
Side to side alignment
Recommended method:
After the sub-deck is welded or bolted down, (to container not drive unit) use a straight
edge to align the drive shoes with respective 25mm x 25mm [1” x 1”] tubing. Do this with
at least two shoes on each side of the container (Figure 11).
Optional method if container is perfectly straight:
Align the drive unit’s “centerline” marks with the container’s centerline.
