Area of application
Beronius types 103 and 104 were designed for special forgings in manufacturing, while the two large hammers, 101 and 102 were designed for hand and machine forgings at engineering workshops.

The hammer head is made of forged open-hearth steel. The height of the impact, which is regulated by altering the connecting rod's length, is adjusted to suit the thickness of the material being forged.

The hammer was started by a foot-operated pedal and the force of impact could easily be adjusted.


The Beronius "Spring Hammer for Forging Steel and Iron", of which four different sizes were made, was intended as an auxiliary tool for locksmiths and mechanical workshops, for production-scale forging or wherever the work involved heavy or light forging. It replaced the steam hammer which was more expensive both as regards maintenance and purchase.
