fully retracted. The remainder of the inner boom is
painted white.
The inner boom is equipped with a pointer and jib
capacity decal. The pointer responds to gravity, so
as the boom angle changes, the pointer tracks to
different areas of the decal. The decal is divided in to
two zones - one green, and one white.
The jib pole is equipped with a maximum capacity
decal near the pivot.
The lower boom is equipped with a pointer and color
coded decal. The pointer responds to gravity, so as
the lower boom angle changes, the pointer tracks to
different areas of the decal. The decal is divided in
to two zones - one white, and one red. The pointer
must be in the white zone to use the material handling
system. When the pointer is in the red zone, the
material handling capacity is zero.
Procedure to Determine the Jib Capacity:
1. Check the color of the lower boom angle
indicator. It must be in the white zone to use the
material handling system.
2. Determine the color of the inner boom where it
exits the outer boom. It will be green or white.
3. Read the capacity from the inner boom pointer.
If the boom in step 2 was green, read the
capacity from the green portion of the decal. If
the boom in step 2 was white, read the capacity
from the white portion of the decal.
4. Check the capacity of the jib pole by reading
the decal near the jib pole tilt pivot.
5. The actual lifting capacity is the smaller of the
two capacities determined in steps 3 and 4.
Example – See Figure 4.13
1.
In this example, the lower boom angle indicator
is white, so material handling is allowed.
2. The inner boom is white where it exits the outer
boom.
3. Reading the white zone, the inner boom pointer
indicates 300 lbs capacity.
4. The jib pole tilt decal reads 500 lbs.
5. The actual lifting capacity is the smaller of the
two capacities determined in steps 3 and 4. So,
the actual capacity is 300 lbs.
