Measuring Departure and
Approach Angle
Before checking ground clearance make sure the trailer is
level front-to-back.
Departure and approach angles are measured by running
a string line from the meeting point of the tire and ground
up at an angle to the lowest point on the front or rear of the
trailer. These string lines are shown as dotted lines
(Fig.1)
.
Measure from the front of the frame and make a mark at
60”. This will be the maximum allowable distance for the
location of the center of the C-Jack footpad. The final
location should be as close to the draw bar as possible,
staying within the approach angle
(Fig.1)
