Gjerstad was founded in 1964 by Norwegian machinery contractor Kjetil Moe, who foresaw the need for better buckets for loaders and excavators working in the construction and mining markets.

In 1988, the company moved to its present location in a 6,500 sq m factory equipped with modern production facilities geared to its every need.

In the tunnelling industry, Gjerstad is best known for its unique side-dumping bucket designs, which facilitate loading of dumptrucks and crushers in confined spaces. These are extremely strong, and feature a high quality cylinder with end cushion. Mucking out time is at least 25% less than with other methods, and tyre wear and fuel consumption are reduced, resulting in more production for less cost, with an environmental advantage. More than 90% of tunnel contractors in Norway use side-dumping buckets from Gjerstad, together with an increasing number of clients worldwide.

Side-dumping buckets from 2 cu m to 7 cu m are manufactured, to match the biggest loader in proportion to the available space. Gjerstad will recommend the best size of loader and bucket for any tunnel profile.

The company also manufactures a wide selection of buckets for loaders and excavators, together with several models of quick couplers. Excavator buckets are available in all sizes for all jobs, and with a variety of teeth configurations for good penetration and breaking. All are made of high quality wear resistant steel. Loader buckets are supplied for all applications with straight, Vee or spade nose edge, and can be delivered with teeth or bolt-on wear plates.
