Abstract: A roller cutter unit is mountable at a cutting head of undercutting mining machines. The cutter unit includes an elongate mount shaft to position and support a cutter ring. The cutter ring is secured to the mount shaft via a bracket having a wedge segment configured to be wedged axially and radially between the cutter ring and the shaft. Accordingly, a mounting mechanism is provided to achieve a desired force transmission pathway from the cutter ring into the shaft so as to maximize the locking action of the cutter ring at the cutter unit.

Abstract: A mountable construction in the form of a deflection device for a belt for continuously conveying material includes a first support frame arranged in a first direction and a second support frame arranged in a second direction, the support frames being coupleable with each other. First and second belt deflectors are arranged in connection to the support frames, wherein the first belt deflector is arranged substantially vertical and the second belt deflector is arranged substantially horizontal. A connection module couples the second support frame with the first support frame, the connection module being arranged such that the second support frame is coupleable to the first support frame at a variable or different horizontal angle. A method for deflecting a belt is also provided.
