Highlighted Features

Highlighted Features

Automatic Shut-off

When no longer in contact with material, the hammer stops firing to prevent premature damage and protect your investment. So no matter who uses the machine, you'll always avoid blank firing.

Buffering

Internal buffering reduces vibration transmitted to the machine to improve operator comfort and reduce machine wear. Built-in accumulators also smooth the flow from the hammer to the machine to protect the hydraulic system from pressure spikes.

Silencing

These hammers are fully enclosed for superior noise suppression, making them ideal in work areas where noise is regulated, while improving job site safety.

DIY: 3 Ways to Keep Costs Low

We build Cat hammers to increase your uptime and lower your maintenance costs.

1. Greasing

Large hammers offer optional automatic greasing through a continuous metered flow. You can easily monitor levels during operation and, with a grease cartridge that doesn't require any tools, you can simply take the old one out, screw the new one in and get back to work.

2. Field-Serviceable Lower Tool Bushing (LTB)

As the primary point of wear, this needs to be replaced regularly on any hammer – regardless of brand. But LTBs on Cat hammers can be serviced in the field by the operator with minimal tooling. And you'll get two uses out of it. After the first wear, just rotate the bushing 90.°

3. Check and Fill Gas Charge

Unlike other brands, the gas charge in a Cat hammer can be checked, and filled, right on the machine. Instead of being part of your daily "routine maintenance," checking the gas charge can be done once a year. That's because we produce a world-class sealing system that handles the hard-hitting work you do and maintains its power output long after other brands.

Watch our videos to learn how to complete these easy maintenance tasks.
