60’ TO 230’ MAIN BOOM ON TIRES

Notes:

1. Boom geometry shown is for unloaded condition and crane standing level on firm supportingsurface. Boom deflection, subsequent radius and boom angle change must be accounted forwhen applying load to hook.

2. Maximum and minimum boom angles are equal to the values listed in the capacity chart for eachboom length.
