DETERMINE MHC SETTINGS FROM RANGE DIAGRAM
1.
Determine load distance from MHC and locate dimension along bottom horizontal line
(1). (Example: Load is 10 ft (3.1 m) from MHC.)
2.
Follow line vertically up graph until it intersects with boom length arc (2). Mark
intersection point (3).
3.
Follow line along arc and make note of boom length (4). (Example: If load distance is
10 ft (3.1 m) from MHC, boom length is 12 ft (3.7 m).)
4.
Return to intersection point (3). Follow diagonal line (5) to determine boom angle
setting (6). (Example: Boom angle setting is 33 degrees from intersection point.)
5.
Return to intersection point (3). Follow horizontal line (7) to determine boom height
(8). (Example: Boom height is 16 ft (4.9 m) from intersection point.)
