Operators can choose between a piston rod guard for the
cylinders, bottom boom protection for the stick or monoblock,
wear plates on the undercarriage and many other individual
measures for protecting both man and machine.
1. Piston rod guard
• Simultaneously moving metal covers protect the chrome-plated
piston rods against damage.
• Available for bucket cylinders (all machine types), hoist cylinders
on R 956 to R 980 SME, crowd cylinders for front shovel
machines from R 956 to R 980 SME.
2. Hoist cylinder hose protection
• Protection for hydraulic lines and line-break protection
for hoist cylinders.
• Optional for R 936 to R 950 SME.
3. Bottom boom protection for stick and monoblock
• Prevents damage to the stick and the monoblock.
• Protects the underside of the stick (bottom boom) and/or the
monoblock with a solid metal cover.
• Especially suitable for working under hard conditions.
• Stick: available for R 936 to R 980 SME.
• Monoblock: available for excavators R 918 to R 980, R 936
to R 960 SME.
4. Protection for slewing mechanism and
lubrication lines
• Protects the slewing mechanism and the lubrication lines in this
area against damage, especially during drop-balling.
• Covers the slewing mechanism and the lubrication lines.
• Available for excavators R 950 to R 980.
5. Protective grille for driver’s cab
• Protective grille in front (FGPS) and top (FOPS) area of the
driver’s cab protects against flying stones.
• Available for all types of machines.
6. Armoured glass

with impact resistant armoured glass, offering additional
protection for the driver.
• Available for all types of machines, standard for R 966.
7. Guard plate
• Protects the undercarriage against damage and wear, especially
when working on loose piles of material and/or during drop-
balling.
• Available for R 950 SME to R 980 SME.
8. Travel drive guard and reinforcement kit for
transmission bearings
• Reinforcement panels protect the outsides of the travel drive
and the transmission bearings on the inside of the longitudinal
members against damage (e. g., when working on piles of loose
material).
• Available for excavators R 950 SME to R 980 SME.

Protective devices
for crawler excavators
Several excavator components are at risk of damage caused by flying stones when working in the quarry,
especially when drop-balling. Liebherr has developed special protective measures for such operations
to prolong the service life of the most important components.
