Full serviceability of the industry’s easiest, lowest cost, body-rebuild system

Hammers aren’t meant to have an easy life and occasionally need to be rebuilt. An NPK hammer body can be re-sleeved for approximately 1/3rd the cost of competing brands when the body becomes worn or damaged. A typical hammer body can cost as much as 70% the cost of a new hammer so when you buy an NPK hammer you can expect an excellent return on your investment.

The PH06 is the smallest hydraulic hammer NPK offers and is best suited for mini excavators in the 1.2 to 2.2 ton range.

Durability and serviceability are two key advantages of NPK hydraulic hammers. When maintained and serviced regularly, NPK hammers can last over 20 years!

Hammer mounted automatic lubrication systems are an optional add-on for models ranging from PH-3 to GH-50. This type of auto-lube is ideal for hammers beingused by multiple machines. For dedicated hammer carriers NPK offers a carrier mounted auto-lube system.

PH Series hammers are available with either the standard hammer bracket or an optional enclosed bracket. This enclosed bracket design decreases operating noise and can be readily equipped with an optional water-ready dust suppression kit.

NPK’s enclosed hammer bracket option decreases operating noise beyond standard low noise brackets. Additionally, the enclosed hammer bracket is much narrower than our standard hammer bracket and may be preferred in some trenching applications

Vibration control that increases operator comfort to increase efficiency

Standard on all medium and large NPK hydraulic hammers, our shock-absorbing mounting bracket uses special heavy-duty rubber mounts to absorb shock, recoil, and impulse vibration. The unique one-piece design eliminates the need for mechanical springs and overly heavy mounting brackets. The net result is minimization of machine wear and improved operator comfort for greater reliability and productivity.

A grease port is provided for automatic and/or manual greasing of the demolition tool. This prevents damage or premature wear caused by a lack of grease.
