Power consumption
The power of the engine used in an electric or
gasoline demolition hammer. This parameter is used to indicate the total power consumption (useful power is less due to losses in the mechanisms) and, accordingly, it determines the connection requirements: the power grid must be able to deliver the required current without overloads and failures.
In general, the more powerful the tool, the better it is able to handle hard materials or large volumes of work. High power values make it possible to provide adequate energy for each individual impact and/or numerous strokes per minute. At the same time, we can say that power is a secondary parameter, and when choosing, you should look primarily at more practically significant characteristics — the same impact energy or impact frequency.
Impact rate
The maximum number of blows that a demolition hammer can deliver in a minute.
The higher this indicator (with the same impact energy, see above) — the more performant the tool, the better it is suitable for large volumes of work. In addition, the high frequency of operation is also able to compensate to a certain extent for the low impact energy: the pike can overcome a small amount of material in one blow, but if there are many such blows, the difference from a more advanced demolition hammer may not be so noticeable.
For different types of work, the optimal number of strokes will also be different; specific recommendations can be clarified by special sources.
