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

(60"/1524 mm), while interlocking legs

close down to 5"/127 mm 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.

Pins. 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.

Caterpillar Grapples

Caterpillar Forest Machines combined with Cat Log Loading Grapples mean optimal

performance, reliability and on-the-job productivity.
