LOAD/LUFFING DRUM 3
System Components
See Figure 1-26, Figure 1-27 and Figure 1-28.
The load/luffing drum 3 is located in the boom butt. The drum
can be configured either for luffing jib operation or as an
auxiliary drum. If drum 3 is rigged for luffing jib operation it
cannot be used as a load drum.
One hydraulic pump drives one motor gearbox on the left
side end of drum 3. The left travel pump is dedicated to
operate drum 3 though a diverging valve. The left track and
drum 3 cannot be operated at the same time. Hydraulic
connections between the pump and the motor form a closed-
loop system that is controlled with the control handle
movement and node controllers. The far load drum control
handle on the right side console operates drum 3 when
configured as a load drum. When configured as a luffing jib,
the control handle on the left side console operates drum 3.
