A tooth system for a cutter head includes a tooth member comprising a cutting portion and a mounting portion with at least one curved surface, a holder comprising a receiving portion with a curved surface complementary to the at least one curved surface of the tooth member, the receiving portion for receiving the mounting portion of the tooth member. The mounting portion of the tooth member detachably engages the holder such that when engaged, the at least one curved surface of the tooth member and the receiving portion curved surface contact each other at a contact area.

Adapter system for cutting tooth

A tooth with a retaining system for retaining the tooth in a receiving portion of an adapter in a cutting system comprises a first holding system to releasably retain the tooth to the adapter; and a second holding system to tension and secure the tooth with respect to the adapter.

Tooth retaining and locking system

A method of forming a cutter head with an axis of rotation comprises forming a hub; forming at least one ring with integral cutter body arm segments extending from the at least one ring; and connecting the hub to the cutter body arm segments so that the hub and the at least one ring are connected and around the axis of rotation.

Cutter head

A tooth system for use in an earthmoving device, includes a tooth and an adapter onto which the tooth is mounted in a detachable fashion, the tooth including a longitudinally extending tooth web, a longitudinally extending tooth base and a longitudinally extending tooth head at a distance from the tooth base, the tooth base and tooth head also extending transversely with respect to the web. The adapter includes an adapter base intended to be fixed onto an earthmoving device, such as onto the teeth bars of a draghead, and an adapter head, a longitudinally extending undercut cavity being defined between the adapter base and the adapter head, wherein the tooth base is slidably fitted within the undercut cavity and wherein the adapter head is slidably fitted between the tooth base and the tooth head for mounting or dismounting the tooth with respect; to the front end of the adapter.
