Do You Really Need To Dig?

There is a lot of older information online, often written based on even older information, suggesting that every power hammer requires a massive isolated foundation.

In the days of large industrial steam hammers and heavy production drop hammers, this was often true. Once a hammer reaches a certain size, substantial foundation work absolutely does become necessary.

But the reality is, with many of the smaller and mid-sized Anyang hammers we see installed, extreme foundation work is often unnecessary.

At the same time, poor installation absolutely can create problems - whether that is excessive vibration, unnecessary wear, a dangerous working environment, or issues with the machine itself.

The goal is not simply to make the machine run. The goal is to make it run properly.

Like many things in forging, there is a balance between overcomplicating the process and ignoring fundamentals entirely.

When To Dig

In some situations, even a smaller hammer may still benefit from an isolated foundation, particularly where maximum vibration reduction is desired or the existing floor is of questionable quality.

As hammer size increases, foundation requirements naturally become more important. Once you move beyond the smaller-class machines and into the 40kg+ range, isolated pads often become more common, especially in lighter buildings or environments.

Ultimately, however, it depends heavily on the quality of the existing floor.

A thick, well-reinforced concrete slab may already provide more than enough mass and rigidity for many installations, whereas thinner or lower-quality floors may struggle even with comparatively modest machines.

This is why there is no single “correct” answer that applies to every workshop.

Some users prefer a more conservative, belt-and-braces approach regardless of hammer size, particularly where long-term vibration reduction or building protection is a priority.

If in doubt, it is always sensible to seek proper structural advice before installation.

You can see an example below of the more substantial isolated foundation approach often used with Sahinler Power Hammers.

What Most Small & Mid-Sized Hammers Actually Need

For many workshops, installation is considerably more straightforward than expected.

Hammers in the 15kg–40kg class are commonly installed directly onto existing concrete floors using mechanical or chemical anchors, often combined with some form of vibration isolation between the machine and the floor.

Some users prefer mounting directly to concrete for maximum rigidity and “feel.” Others use rubber matting, horse stall mats, plywood layers, or combinations of all three to help reduce transmitted vibration and high-frequency noise.

All of these approaches can work when applied sensibly.

Rubber isolation can help reduce harsh vibration transfer into the building, particularly in smaller workshops or residential environments.

Horse stall matting has become particularly common because it is inexpensive, dense, durable, and easy to source. Others opt for plywood or layered combinations.

Like many things in blacksmithing, there is rarely one universally correct answer.

Anchoring Matters

Whatever you choose to place between the hammer and the concrete, proper anchoring remains one of the most important parts of installation.

Even a well-built hammer can feel rough, unstable, or unpleasant to use if it is not securely installed.

When anchoring your machine, proper levelling is equally important.

A hammer sitting unevenly on the floor can behave very differently under load. Small inconsistencies in levelling can sometimes create vibration patterns, unusual noises, or operating issues.

It is also worth remembering that anchors often settle slightly during early use. Re-checking anchor tightness after the initial running period is a very sensible.

Noise Reduction & Sound Dampening

Reducing vibration is one part of installation, but for many users controlling noise is equally important. While anti-vibration matting can help reduce high-frequency vibration transfer into the building, some workshops require additional measures to soften the overall sound and resonance these machines create during operation.

One approach for Anyang Power Hammers is introducing sand into the base . The idea is to help dampen resonance and absorb some of the harsher vibration and ringing that can transfer through the machine.

This is generally a relatively straightforward process and, can make a noticeable difference to the character of the sound produced by the machine.

The Most Common Installation Mistakes

Most installation issues are not catastrophic mistakes. More often they are small oversights that gradually create larger problems over time.

Weak or damaged concrete is one of the more obvious examples, particularly in older workshops where years of moisture, cracking, or previous machinery have already compromised the floor beneath the hammer.

As already mentioned, levelling and anchoring play a major role in how a hammer behaves under load.

Other issues are less dramatic but equally common. Excessive oiling, overly soft isolation materials and undersized electrical supplies can all change how a hammer behaves during operation.

First Start-Up & Early Running

The first few operating hours are often when a new installation begins to settle into place.

During this period it is particularly worth paying close attention to how the machine behaves. Anchor tightness, lubrication, vibration transfer, and general machine movement can all change slightly as the hammer beds into its final operating position.

This is also the stage where small installation issues often reveal themselves for the first time. A potential issue may not become obvious until the hammer has spent some time under load.

It is good practice to allow the machine to warm up gradually rather than immediately pushing it into heavy forging work. Like most machinery, self-contained hammers tend to operate more smoothly once everything has settled into normal operating temperature and rhythm.

Final Thoughts

Most modern self-contained power hammers are considerably easier to install than some internet guides suggest.

A properly installed hammer should feel controlled, predictable, secure, and enjoyable to use.

And in many cases, good installation practices will do far more for long-term reliability than adding another foot of concrete ever will.
