High Pressure AccumulatorA high-pressure accumulator located on the back side of the hammer protectsthe carrier pumps from hydraulicpressure spikes.

Power Cell ConstructionTie rods, cylinder and piston protectedfrom prying forces. Locking mechanismprevent loosening of tie rods clampingthe hammer assembly.

Energy EfficientMatching the mass and diameter of the piston to the mass and diameter ofthe tool helps ensure optimum energytransfer.

Hydraulic Hammers H45, H50, H63, H70, H90C and H100For Mini Excavators, Skid Steers and Backhoe Loaders

Slip Fit Lower Tool BushingSlip fit field serviceable lower toolbushing with internal dust seal. Bushing includes grease retentiongrooves for better lubrication.

Membrane style accumulatorMembrane accumulator versus gasaccumulator meaning less maintenanceand less downtime resulting in moreproductivity.

Sound suppression Sound suppressed models available:H45 s, H50 s, H63 s, H70 s, H90Cs andH100 s.

DependabilityService and parts available through the worldwide Cat Parts System.

High Blow RateVery high blow rate means very highproductivity for all hammers.

Wide Carrier VersatilityWide range of oil flow matches moreCat and other machines and reduceslikelihood of improper machine setting.

Constant Blow EnergyMaximum and constant blow energyregardless of the oil flow adjustment(within the given min and max oil flowspecifications).

Full Length Side PlatesPowercell completely protected throughfull-length side plates. Front head is notexposed.

Hydraulic Hammers H115 s, H120C s, H130 s, H140D s, H160D s and H180 sFor Hydraulic Excavators

Dust SealA Dust Seal prevents foreign materialfrom entering the housing. This reduceswear on the power cell and other majorcomponents.

Special ApplicationsBuilt-in lubrication port and air portmake it easy to convert the hammer to automatic greasing and underwateruse.

High Pressure AccumulatorHigh Pressure hydraulic accumulatoraccounts for 80% of the striking powerand protects both the hammer circuitand carrier pump from hydraulicpressure spikes.

Sound SuppressionAll large hammer models are deliveredin sound suppressed version. This results in greater operator comfortand environment protection.

Maximum PowerThe simple and effective design of the powercell helps producemaximum power, a single piston andsimple valving being used.

Field Replaceable Lower Tool BushingSpecial care is given to the lower toolbushing. It is slip fit (can be replacedwithin minutes in the field), rotatable(“double” lifetime), includes innergrooves for longer grease retention, and a seal to keep dirt outside and noiseinside. This is a cost saver as the lowertool bushing and the tool are the itemsmost exposed to wear.

Sealed HousingPowercell protected, fully enclosed in housing. Bottom of housing is closedand sealed whilst covers preventmaterial intrusion on the top.

Hammer & Carrier ProtectionThe effective suspension system,including buffer and side pads, not onlyprotects the hammer but also the carrierfrom recoil forces.

Auto Shut Off (ASO)Prevents blank fire by stopping thehammer as soon as there is no materialpresent to be broken. Reliability anddurability of the hammer are increaseddue to elimination of high stress levelsresulting from blank firing (availableonly for H140D s and H160D s).

Hammer Models H45, H50, H63, H70, H90C and H100

1 Low Pressure Accumulator – Assists in the power stroke of the piston.

2 Custom Sideplates – Designed for Caterpillar carriergeometry. Protects the powercell and front end.

3 High Pressure Accumulator – Dampens pressure peaks thusprotecting the carrier hydraulic system (not shown).

4 Distributor – High oil volume for greater blow frequency.

5 Pressure Adjusting Valve (PAV) – Assures that all blows are delivered at a constant blow energy.

6 Piston – Long heavy piston delivers maximum impact energyand minimizes recoil forces to carrier.

7 Long Front End – Ensures proper piston tool alignment.

8 Slip Fit Thrust Ring – Dissipates harmful shock loads inabusive applications.

9 Slip Fit Upper Tool Bushing – Positive alignment for the tool.

10 Tool Retention Pin System – Allows quick and easy removalof tool.

11 Side Plate Fastener – Working forces carried through capscrews and front end.

12 Slip Fit Lower Tool Bushing (Field Replaceable) – Grease retention grooves for extended lubrication and wear indication.

13 Dust Seal – Dust Seal helps prevent foreign material fromentering the housing. This reduces the wear on the power celland other major components.

14 Tool – Heat treated for longer life. Ideally matched to pistonfor greater transfer of stress waves.

Hammer Models H115 s, H120C s, H130 s, H140D s, H160D s, H180 s

1 Shock Absorbers – Provide maximum shock and recoil protection for both hammer and carrier.

2 Accumulator – Self-contained diaphragm accumulator designed for long life.

3 Housing – Symmetrical lean enclosed housing – no parts to break through external shock.

4 Hydraulic valves – The Pressure Control Valve maintains maximum hydraulicpressure to ensure that the hammer delivers all blows at full power. A check valveisolates harmful pulsation spikes from the carrier hydraulic circuit.

5 Auto-Lube Connection and Grease Channel – Ensures proper greasing of the tool as well as the upper and lower tool bushings.

6 Auto Shut Off (ASO) – Prevents blank firing and extends hammer life by reducinginternal stress and heat (available only for H140D s and H160D s).

7 Seal carrier – Contains special high performance seals to ensure leak-proof operation.

8 Hydraulic brake – Dampens idle strokes and prevents steel to steel contact between piston and cylinder.

9 Piston – Long piston transfers a long shock wave into the rock. Tool-piston diameters are matched for maximum energy transfer.

10 Tie-Rods – Heat-torqued tie rods ensure maximum clamping force and minimum maintenance.

11 Cylinder – Low recoil stress.

12 & 15. Wear Plates – High abrasion resilient plastic wear plates between hammerand housing reduce noise and guide hammer assembly properly.

13 Upper tool bushing – Guides the tool to optimize in-line piston to tool contact.

14 Tool retaining pins – Allow quick and easy tool maintenance.

16 Rock Claw – Special high abrasion resistant rock claw, enables quickpositioning of boulders, gives maximum wear life.

17 Lower tool bushing – Easily replaceable during normal maintenance.Circular retention grooves retain grease and lower friction between tooland bushing.

18 Dust Seal – Dust Seal helps prevent foreign material from entering thehousing. This reduces the wear on the lower bushing and tool.

19 Tool – Specially heat-treated tools match piston diameter and mass,to deliver full blow energy.
