Measurement
Boom Pivot Dimensions
L
The horizontal distance between the center of the
boom pivot and the center of the boom hoist cylinder
upper pivot.
J
The vertical distance between the center of the boom
pivot and the center of the boom hoist cylinder upper
pivot.
Note: If the boom pivot is above the boom hoist
cylinder upper pivot the dimension is negative
.
G
The horizontal distance between the center of the
boom pivot and the center of the boom hoist cylinder
lower pivot.
H
The vertical distance between the center of the boom
pivot and the center of the boom hoist cylinder lower
pivot.
Winch Dimensions
G0
The horizontal distance between the center of the front
winch and the center of the boom pivot.
G1
The horizontal distance between the center of the rear
winch and the center of the boom pivot.
H0
The vertical distance between the center of the front
winch and the center of the boom pivot.
H1
The vertical distance between the center of the rear
winch and the center of the boom pivot.
J0
The distance between the top sheave and the
centerline of the boom pivot parallel to the horizontal
boom plane.
J1
The distance between the top sheave and the
centerline of the boom pivot parallel to the horizontal
boom plane.
L0
The distance between the centerline of the boom pivot
perpendicular to the horizontal boom plane and the
center of the bottom sheave.
L1
The distance between the centerline of the boom pivot
perpendicular to the horizontal boom plane and the
center of the bottom sheave.
N
Swing Offset – The horizontal distance between the
center of the boom pivot and the centerline of rotation.
R
Sheave Radius – The distance between the center and
the outside edge of the bottom sheave.
