Spring-Actuated Pallet Carousel Skid Positioner

READ & SAVE THESE INSTRUCTIONS

INTRODUCTION

The Spring-Actuated Pallet Carousel Skid
Positioner is a simple device which will
automatically maintain a load at the ideal
height for manual loading and unloading.
If a palletized load is placed on the unit,
the unit gradually rises as boxes or parts
are removed. This automatically maintains
the top of the load at the correct working
height.

If an empty pallet is placed on the unit,
it gradually lowers as boxes or parts are
added. Again, this keeps the top of the load
at the correct height. Completed pallets
may be loaded or unloaded using a fork lift.

Each unit includes a steel scissor
lift mechanism and at least one large
compression spring. The springs are
chosen to match the weight and height of
a fully loaded pallet. Springs are available

for a wide range of weight and height
combinations. The unit also includes
a shock absorber. This eliminates any
tendency for the load to bounce on the
springs.

This manual contains information to help
you to learn about the safe and proper
installation, use, and upkeep of your unit.
Please be sure that this manual is available
to anyone who uses or services the unit.

These units may be used in a wide variety of
industrial settings. The instructions in this
manual are not necessarily all-inclusive,
as Global Industrial cannot anticipate all
conceivable or unique situations. In the
interest of safety, please read this whole
manual carefully. Be familiar with the
contents of this manual before you install
or use this unit. If you are not sure of the

OPERATION NOTES – MANUAL USE

WARNING!

• Never operate the unit if anyone is sitting or
riding on the rotating ring.

• Never operate the unit if the load is off center.
The load may shift, and you may be injured.
This can also damage the unit.

• As the unit moves, keep away from the “pinch
points” where metal parts meet.

•

Keep the area around the unit clean. Do not allow
any dirt, debris, spilled oil, or excess grease to
collect. These materials may cause you to slip
while the unit is operating, and you may be injured.

• Stay clear of the rotating ring when it is
moving. As the pallet turns, a part of the load
may rotate around and hit you. Never turn the
load when anyone is standing beside the unit.

• Do not try to use this unit with damaged
or broken pallets. Broken pallets may have
boards or nails which hang down below the
main part of the pallet. As the pallet is turned,
these boards or nails may catch on the
frame of the unit. This can cause the pallet
to stop turning suddenly, causing the load to
shift. You may be injured, and the unit may be
damaged. The boards or nails on the bottom of
the pallet should not extend down more than
1/8 inch.

damage which may have affected the unit.
If you see signs of damage, tell the trucker.
Also make a note of this on the shipping
papers which you are asked to sign.

4. Choose the place where you want to use the
unit. It is very important that the unit be set
up on a smooth and flat surface. Check the
floor surface carefully and make sure that it
is free of all loose debris and dirt.

The unit must be installed on a smooth flat
surface. If the floor is not flat, this can create
stresses in the frame of the unit. The unit
may not work properly, or parts of the
unit may wear more quickly than they
should. You may be hurt or the load may
be damaged.

should be stable, and should not move.
Check to see that the base frame is level.

8. Remove the springs and lay them out on
the floor.

9. If you have any questions about the steps
in the installation process, please call
Global Industrial Customer Service.

SETTING UP AND INSTALLING THE SPRINGS

1. The unit will always have at least one spring.
This spring has an orange mark, and is
larger in diameter than the others. This large
orange spring is always placed in the front of
the unit. Figure 3 shows the position of the
first spring. The frame of the unit can handle
loads of up to 4500 lbs. In order to adapt the
unit for different pallet loads, the springs are
changed. The springs are chosen to match
the weight and height of a fully loaded pallet.
A unit may have one to three springs. Each
time the pallet weight or pallet height is
changed, the springs may also need to be
changed. Table 1 shows how the springs
are selected.

2. The unit is shipped without springs installed.
The installation of the first spring (orange)
requires two people. Lift off rotating ring and
both yellow bayonets. Set them aside, they
will be installed later.

3. The shock absorber is attached to the top
frame of the unit with a pivot pin, and this
is held in place by a linch pin. The pivot pin
is used to hold the table frame in the raised
position. Take a look at the mechanism and
note the positions of the parts. Remove the
linch pin and remove the pivot pin. Lay the free
end of the shock absorber down.

OPERATING SAFETY

1. Do not use this unit with a load greater than
the rated load. This includes the weight of the
payload and the weight of the pallet. Table 1
shows how to be sure you have the correct
spring combination for your application.

2. Never push the load off of the side of the
unit. If you do this, the frame of the unit may
jump upward.

3. Never use the unit when anyone is sitting or
riding on the rotating ring.

4.

Do not try to use this unit with damaged
or broken pallets. Broken pallets may have
boards or nails which hang down below
the main part of the pallet. As the pallet is
turned, these boards or nails may catch
on the frame. The pallet may stop turning
suddenly and this can cause the load to
shift. You may be injured and the unit may
be damaged. If the boards or nails on the
bottom of the pallet extend down more than
1/8 inch, they will interfere with the turning
action.

5. Stay clear of the rotating ring when it is
moving. As the pallet turns, a part of the load
may rotate around and hit you.

6. Keep the area around the unit clean. Do not
allow any dirt, debris, spilled oil, or excess
grease to collect. These materials may cause
you to slip while the unit is operating and you
may be injured.

LOADING WITH A FORK LIFT

1. Place the load on the fork lift, then lower the
fork lift. Before removing the load, be sure
the unit is carrying the weight, not the fork
lift. See Fig. 21.

• Lower the load until the springs on the

unit are fully compressed.

• Be sure the forks on the lift are clear of

the inside of the pallet.

WARNING!

If you skip these steps, the load may drop
suddenly when you remove the fork lift. You
may be hurt or the unit or load may be
damaged.

WARNING!

Never drop the load on the rotating ring. If you
do this while the rotating ring is moving, the
load may shift. You may be injured or the unit
may be damaged.
