Payload Calculations
FIGURE 1: PAYLOAD CALCULATION
The maximum payload calculation is based on the magnet’s ability to resist the gravitational moment (or
torque) induced at the driving surface. When payload weight and/or distance from the wall is increased,
the vehicle tries to pivot away from the wall and the magnets resist this moment. When the maximum
payload moment is exceeded, the vehicle may fall off the driving surface during operation. The payload
moment may be calculated as follows:
𝑀 = 𝑊 × 𝐷 ≤ 5.8 kg · m (500 lb · in)
Where W is the weight of the payload, and D is the distance of the center of gravity of the payload from
the driving surface. Note that the chassis and tether weight has already been accounted for and does not
have to be included in customer payload.
The above calculation is for operation on
flat surfaces
. Payload calculations are de-rated for operation
on curved surfaces.
