CASE MOVEMENT

The BB cases are shipped with wood planks that allow the use
of pipe rollers.  These wood planks should be removed after the
case is moved to its final location (Figure 6).

The RVC/P and BB cases have steel protective support plates
under the ends (not under insulated dividers).  These are de-
signed to protect the end from Johnson bar damage.

Use the following methods to move the cases.

Model

Fork lift

Johnson Furniture

Pipe

Safe (case)

from ends

bar

dolly

rollers

jacks

RVC/P 30 & 24

RVC WA & WB

*

RVC/P BB

* Fork lift from rear

Care should be taken when moving the cases.  The doors should
be secured so they cannot open while the case is moved.

Only experienced certified fork truck drivers should use fork
trucks to move the cases.  The case should only be lifted off
the floor as high as necessary for transport. The fork truck
should be driven slowly avoiding any abrupt motions or bumps.

The following fork lift dimensions must be maintained to avoid
damaging the case when it is lifted.

2-DOOR CASES:

Forks must extend from 26” to no more than 30” under the
case.

3-DOOR CASES:

Use 48” long Forks!
Forks must extend from 39” to no more than 43” under the
case.

4 & 5 DOOR CASES:

Use 48” long forks!
Forks must extend from 44” to 47” under the case.

Fork blades wider than 4 inches will not fit in the bases.

Spacer blocks are factory installed in the end bases of 4 and 5
door cases that use 4 1/2” bases (Figure 7). These blocks limit
the cases forward tilt while it is being lifted and must be used
when lifting 4 or 5 door cases with 4 1/2” bases.

For low shipping height applications, Zero Zone has optional
expandable bases.  As shipped, the base is 1¾” tall.  It is
attached with spacers that allow the base to slide away from
the bottom of the case creating a gap that allows the use of a
1½” thick fork truck blade (Figure 8).
