Our Family
of Companies
J.M. Grimstad has grown its capabilities through strategic acquisitions — bringing deeper expertise across hydraulics, metal baling, and marine systems, all under the same employee-owned commitment to quality.
Henning
Reduces scrap volume up to 90%, cutting storage, labor, and transport costs. Grimstad has designed controls and power units for Galland Henning balers for over 20 years — now fully integrated under one roof.
Specialists
GT's team has joined Grimstad at our Muskego facility. Together we deliver true single-source design, build, and field support for hydraulic systems across industrial and marine applications.
Winches
Collomatic winches deliver smooth, precise tension and rendering control — keeping vessels safely berthed under shifting wind, tide, and wake conditions. Now owned and manufactured by Grimstad, every winch is fully run-in and tested in-house before shipment. New builds and complete OEM rebuilds available.
