Above on the page there are several PDF Parts Manuals for HYMAC Excavators.
The world's first hydraulic full-circle crawler excavator appeared in England under the Hymac brand in the early 1960s.
Now hardly anyone will remember this company, but in those days it occupied a dominant position in the world market - production volumes were measured in thousands of units per year.
Hymac was ruined by the dizziness of success and unwillingness to keep up with the times.
The last 18-ton Hymac 181B wheeled excavator was produced in 1993 and ended the history of this famous British brand.
Hymac simply could not compete with Japanese manufacturers, whose products showed more modern design, high performance and complete absence of leaks.
Obviously, among them was the Japanese company Kobelco, which at that time was already firmly entrenched in the European market.
