Determining Load Torque
Requirements
IMPORTANT:
Positioning the load as close to center as
possible will reduce the torque requirements and increase
truck stability.
To make sure your Rotator will handle a specific load,
calculate the torque requirements as follows:
1
Weigh the load to be handled. Example: 1500 lbs.
2
Determine the center of the rotator faceplate. Draw a
line between a set of faceplate holes that are 180˚ apart.
Repeat for a second set of holes. Where they cross is
the center point of the rotator.
3
Determine the vertical off-center distance of the load.
Measure from the load vertical centerline to the rotator
vertical centerline.
4
Determine the horizontal off-center distance of the
load. Measure from the load horizontal centerline to the
rotator horizontal centerline.
5
Off-center distance calculation.
•
Square the vertical measurement.
Example:
(3 in.)² = 9 in.
•
Square the horizontal measurement.
Example:
(4 in.)² = 16 in.
•
Add these two figures together.
Example:
9 in. + 16 in. = 25 in.
•
Determine the square root and you have the total off-
center distance.
Example:
25 in. = 5 in. off-center distance
•
Multiply the total off-center distance by the load
weight and you have the torque required to
handle the load. Compare this figure to the rotator
specifications in the chart.
Example:
5 in. x 1500 = 7500 in.-lbs.
