Figure 7: Platform Deck Dimensions, for Attaching Payload Structure with M5-threaded bolts
In the preceding figure, all of the M5 PEM nuts (A) have a torque limit of 14 N-m (124 in-lbf).
NOTE:
The M6 PEM nuts are inserted differently than the M5 PEM nuts, to increase the
usable thread length. This also decreases the torque that can be applied to them,
so the M5s have a much higher torque limit than the M6s in this application.
Center of Gravity
As much as possible, you should keep the payload structure center of gravity centered on the LD platform,
and as low (close to the platform top) as possible. This will give you the best stability, particularly when
crossing thresholds or irregularities in the floor.
The payload should be centered on the platform left-to-right, but biased toward the rear of the platform or
cart according to the following figures.
The following figure shows the center of gravity of the platform, without payload structure.
