  • Publication number: 20240110477
    Abstract: A method for controlling movement of a movable element of a mining machine includes the steps of providing a relation between control values for a hydraulic valve arranged to affect a movement of the movable element and a parameter representative of the (resulting) movement of the movable element. The method further includes receiving an input representative of a desired movement of the movable element, obtaining a control value for the hydraulic valve based on the relation, and using a parameter value corresponding to the desired movement, operating the hydraulic valve with a control signal using the obtained control value, obtaining, from a feedback mechanism, a feedback relative to the movement of the movable element resulting from operating the hydraulic valve with the control signal, determining a correction value based on the desired movement and the feedback, and updating at least a part of the relation based on the correction value.

  • Publication number: 20220259973
    Abstract: A cutter head for excavating hard rock materials in rock face includes a carrier attachable to a cutter arm of a cutter machine and a drive shaft rotatably supported by the carrier. The drive shaft is rotatable about a drive axis and has at one end a support portion for mounting disc cutters. A plurality of disc cutters are mounted on the support portion and configured to perform undercutting against the rock face. Each disc cutter is rotatable about a respective support axis, the respective rotational axis of each disc cutter being configured to be substantially transverse to the rotational axis of the cutter head. A mining machine including the cutter head is also disclosed.

  • Patent number: 10876404
    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.
