Most common factors
to consider when choosing caster:
The first thing to
consider in selecting the right caster is the combined
weight of your equipment and the maximum load. To determine
the load capacity for each caster, divide the combined
weight of your equipment and the maximum load by the
number of casters you are planning to use on your equipment.
For example, your combined weight of your equipment
and the maximum load is 1000 lbs, and you are planning
to use 4 casters for your equipment, divide 1000 by
4 = 250. You should select a caster with 250 lbs capacity
for this particular application. Although every SRC's
caster has a safety load rating factor, we recommend
that you always select casters and wheels that are rated
for a capacity greater than the calculated load per
caster.
Other
factors to consider:
Rolling Ease: The rolling
ease depends on the diameter of the wheel. The bigger
the diameter, the easier the wheel will roll. A narrow
hard crowned tread rolls easier than a flat soft tread.
Load
Weight: The weight of the load also influences
the mobility of the wheel. The heavier the load, the larger
the wheel required for the caster.
Floor
Conditions: Make sure the wheel you select is large
enough to negotiate your particular floor conditions.
This can be cracks in the floor, tracks, moldings and
other obstacles.
If you are not sure
of what casters to use for your equipment, seek help from
a safety or engineering consultant who knows your equipment
and its intended use to assist you.

Four
swivel
This arrangement
can be moved in any direction, forward, backward,
and even sideway. This is the most versatile arrangement.
Use full when there is little space to maneuver and
side motion is frequently needed. Can also be used
with ramps. |

2x2
R
Two rigid two swivel
This
configuration is recommended for straight line, long
distance travel. The two swivel and two rigid casters
give you easy control. Depending on the capacity of
the casters, this configuration can be used for medium
or heavy applications. |
| |
2x2
D
This configuration
is great for maneuverability, the two swivel casters
at each end allow you to better control the turn of
your equipment. This configuration is not recommended
for ramp use. |

Four
rigid tilt
This
configuration is most economical, but should only
be used with very light load. It is not recommended
for ramp use. |
| |
2x4
tilt
Two rigid, four swivel
This configuration is usually used for a narrow
and long tilt cart. The two rigid casters in the
center are usually taller than the four swivel casters
on the corners. This configuration is design to
handle a heavier load with long trucks and still
able to maneuver and steer easily. The two rigid
casters help to distribute and reduce the load on
the swivel units. |
