Weight; Center Of Gravity - Omron LD User Manual

CAUTION: Potential pinch hazard. Ensure that there is enough space between
the HMI post and your payload, when the transporter and cart are coupling,
that it is not a pinch hazard.

Weight

Run-time between charges is a function of payload weight. A heavier payload will result in a
shorter run-time. If you have added any options to the transporter that draw power from the
transporter battery, that will also result in decreased run-time.

Center of Gravity

When adding payload, the center of gravity of the entire cart and payload needs to be con-
sidered.
As much as possible, you should keep the payload center of gravity centered on the cart, and
as low (close to the platform top) as possible. This will give you the best stability, particularly
when turning or crossing irregularities in the floor.
The payload should be centered on the cart left-to-right, but biased toward the rear of the cart
according to the following plots.
The following figures show the calculations of safe placements for the center of gravity for pay-
loads with the weights listed. The center of gravity, in each instance, needs to be within the
area shown. All units are mm.
WARNING: These figures show centers of gravity for the listed parameter set-
tings only. They do not apply to any other parameter settings. Even small
changes in these parameters can change the safe CG area drastically.
