FIGURE 4. DIMENSION A FOR MAXIMUM BOOM ANGLE.
IMPORTANT
DIMENSION A IN THE FOLLOWING TABLES IS MEASURED FROM THE CENTERLINE OF THE
BOOM HINGE PINS TO THE CENTERLINE OF THE LOWER BOOM POINT SHAFT (SEE FIGURE 5). IF A SIN-
GLE PART LINE IS USED OVER THE LOWER BOOM POINT SHAFT, ADD THE RADIUS OF THE LOWER BOOM
POINT SHEAVE TO DIMENSION A IN THE FOLLOWING TABLES.
