The present disclosure relates to a mobile mining machine which may comprise a movable machine base frame, a rotatable tool drum and including excavating tools. The mobile mining machine may further comprise a cantilever unit including a front support arm part and a base part, and a pivotal device to pivot the cantilever unit. The mobile mining machine may further comprise a tilt device to tilt the cantilever unit and a rotary mechanism to rotate the support arm part and the tool drum. Thus, a mobile mining machine with which tunnels, galleries or shafts may be continuously driven in even in hard rock with a high mining output and low tool wear may be provided.

Mobile mining

A restraint system for use in a vehicle may include a seat; a belt system having at least one belt and at least one belt-adjusting mechanism; and at least one buckle. The belt-adjusting mechanism may be disposed at a first side of the seat and the buckle may be disposed at a second side of the seat. An end portion of the belt may be connected to the belt-adjusting mechanism; and the belt system may have a locking member for locking with the buckle. The restraint system may also include a belt pretensioner that includes a force transmission member; and an actuator configured to actuate the force transmission member for tightening the force transmission member and/or the belt. The actuator may be configured to be actuated and/or triggered by an operator.

Restraint system for use in a vehicle

An apparatus for the milling cutting of rock, minerals or other hard materials has a tool drum which is rotatably mounted on a drum carrier about a drum axis and on the peripheral shell surface of which are disposed, in distributed arrangement, a plurality of tool carriers, which carry cutting tools and can be rotatingly driven, where their shaft axes run transversely to the drum axis. A first group of tool carriers and a second group of tool carriers are provided, where the rotational direction of the first group is counter to the rotational direction of the second group, and the shaft axes of the tool carriers of the first group and of the second group are oriented at different setting angles relative to the radial direction of the tool drum.

Apparatus for the milling cutting of rock, minerals or other materials

A mining apparatus includes two tool drums, which are arranged rotatably side by side in twin arrangement on a drum carrier and which are respectively provided with a plurality of tool carriers which support cutting tools arranged over the periphery of the tool drums and which can be rotatingly driven and the shaft axes of which run substantially transversely to the drum axle. The shaft axes of the tool carriers of the first tool drum span a first conical surface about the drum axis and the shaft axes of the tool carriers of the second tool drum span a second conical surface about the drum axis, where the conical surfaces are open to opposite sides and are preferably oriented such that they are mutually inclined in an O-arrangement.

A mobile mining machine includes a movable machine base frame having a boom, a swinging device for swinging the boom, and a tilting device for tilting the boom. At least one tool drum is coupled to the boom for rotation about a drum axis and rotatable tool carriers are arranged on a circumference of the tool drum. The boom has a supporting arm, on which the tool drum is mounted, and a separate swinging base, which is swingable about a swing axis in relation to the machine base frame by the swinging device. The supporting arm and the swinging base are connected to one another by a system of guide bars, by way of which a setting angle of the drum axis in relation to the swing axis is adjustable.
