(3) Determine distance load is from MHC and locate dimension along bottom horizontal
line (1). (Example: Load is 11 ft (3 m) from MHC.)
(4) Follow line vertically up graph until it intersects with boom length arc (2). Mark
intersection point (3).
(5) Follow line along arc and make note of boom length (4). (Example: If load is 11 ft
(3 m) from MHC, boom length is 14.25 ft (4 m).)
(6) Return to intersection point (3). Follow diagonal line (5) to determine boom angle
setting (6). (Example: Boom angle setting is 40 degrees from intersection point.)
(7) Return to intersection point (3). Follow horizontal line to determine boom height (7).
(Example: Boom height is 19 ft (5 m) from intersection point.)
(8) Locate distance load is from MHC in Table 2-22. Wrecker Material Handling Crane
(MHC) Range Diagram Summary.
(9) Follow across table to verify height of boom and to determine maximum load.
(Example: Boom height is 19 ft (5 m) and maximum MHC load is 11,000 lbs (4,994
kgs).)
