Cat 360 Degree Continuous Rotating
Log Loader Grapples. Cat 360 Degree
Continuous Rotating Log Loading
Grapples for Forestry Machines are
high capacity tools, built for endurance
in high-volume logging applications.
GLL grapple legs are made of high-
strength alloy steel with unique leg
profiles for maximum performance in
picking/sorting, bunching/loading or
shoveling applications. Large bunches
of stems or single large logs are easily
handled by the wide grapple opening
1524 mm (60 inch), while interlocking
legs close down to 127 mm (5 inch) for
picking and sorting. Cat grapples have
bolt-on access panels allowing for easy
serviceability and are backed by the
world-class Caterpillar Dealer Network. 360-Degree Continuous Rotation.
High torque hydraulic motor positions
the grapple precisely for rapid sorting
and loading.
Hydraulic Cylinders. Heavy-duty wall
construction delivers durability and
maximum closing power move the
maximum amount of wood per pass.
Legs. Built with high-strength alloy steel
for maximum durability. Optimized
profile performs equally well whether
sorting, bunching or shoveling.
Pin. Induction-hardened alloy pins float,
decreasing wear.
Serviceability. Bolt-on access panels
protect the grapples internal components,
while providing easy access. Long service
intervals and infield servicing result in
more uptime and lower operating costs.
