5.2 Mount the Grapple
IMPORTANT! When mounting the grapple to an excavator,
the following considerations must be met.
1. A mounting bracket must be manufactured to fit your
excavator.
The grapple is not supplied with a mounting
bracket.
2. One of the following hydraulic circuits is required to
power the grapple:
-
Two auxiliary circuits
, one for the open/close function
and one for the rotate function.
-
One auxiliary circuit plus a selector valve kit
(shown
in the following image) to divert fluid flow between the
open/close and rotate functions.
3. If a selector valve kit is installed, 12 VDC electric power
must be supplied by the excavator.
The electrical harness
must be routed along the boom and connected to a power
supply on the excavator.
