The introduction of the new Caterpillar^® H35Ds and H45Ds hydraulic hammers means that compact equipment and mini excavator owners now have a full range of innovative hydraulic hammers designed by Caterpillar.

The H45Ds replaces the H45/H45s hammers. It is in the 300 ft-lb. class (power), up from the 200 ft-lbs of its predecessors, and provides 2,300 blows per minute.  The H35Ds is a new offering that completes the full range of Caterpillar small hydraulic hammers. It is in the 150 ft-lb class and provides 2,900 blows per minute. Both hammers are matches for the 301.6C and 301.8C Caterpillar mini-hydraulic excavators. The H45Ds also matches with the 302.5C mini-hydraulic excavator.

In its family of small hydraulic hammers, Caterpillar now offers a range of energy classes from 150 ft-lbs to 700 ft-lbs. 

The new hammers contain nearly 50 percent fewer parts than the H45/H45s. That means simplified maintenance and reduced owning and operating costs.

Other technological innovations on the H35Ds and H45Ds include the following:

• Simplified design to provide low owning and operating costs along with maximum performance, productivity, reliability, and durability.
  
• Enclosed housing to protect the power cell, eliminate side plate bolts, and reduce sound levels.
  
• Recoil isolation to protect the carrier from damaging reflective forces.
  
• Ultra-high blow rate for greater productivity in concrete and asphalt applications.
  
• High and low pressure accumulator to protect the carrier hydraulic system and assist the power stroke of the piston.
  
  
• Caterpillar design means the hammer is matched to a Caterpillar carrier.
  
• One-piece body eliminates tie rods.
  
• Two-position hose mounting optimizes hose routing.
  
• Single bushing design combines three bushings into one for a slip fit and the ability to be replaced in the field.

Standard sound suppression improves operator comfort and environmental protection. The new hammers are matched to current and next-generation Caterpillar compact machines.
