摘要： The invention relates to a cutting machine (2), comprising cutting or shearing tools (19) which are mounted in such a way that they can rotate, a loading ramp and a conveyor (4) for receiving and removing the cut or shorn material, said conveyor running in the direction of the working face. According to the invention, the cutting or shearing tools (19) are mounted on a carriage which moves on guides extending in the longitudinal direction of the machine. Said guides are formed by pipes or bars which are connected to an engine frame in the area of the tracklaying gear (1), preferably within the frame of the tracklaying gear (1). The carriage is formed by longitudinal spars (10) and a crossbeam (9) for mounting the cutting or shearing tools (19). The machine frame has a box shape (3) at least in the front area adjacent to the crossbeam (9) and the conveyor is guided in the inner width of this box shape in such a way that it can move in the longitudinal direction of the machine.

摘要： A hydraulic assembly (10) for a mining system (100) comprises at least one control valve (2) for controlling a supply of hydraulic fluid to a hydraulic actuator (9, 11) of the mining system. At least one temperature sensor (12) is associated with the at least one control valve (2) and detects a temperature of the at least one control valve (2). A control unit (6) receives the temperature measured by the at least one temperature sensor (12) and an ambient temperature, and determines that a leakage has occurred in at least one control valve (2) when a temperature difference exceeds a predetermined threshold.

摘要： A device to aid the unloading of support elements, the support elements comprising a lower shaft and an upper shaft telescopically coupled to each other. The device includes annular first and second bodies coaxially couplable with each other. Each annular body is provided with a through-hole that allow the upper shaft to extend through the through holes. The upper shaft is also supported by the first annular body using a transversely extending member. The second annular body rests on the lower shaft. An intermediate unloading wedge is positioned between the first and the second annular bodies coupled together, and is able to slide transversally with respect thereto. The sliding of the unloading wedge causes the first annular body and the second annular body to come together or move apart in the longitudinal direction and, therefore, reduce or increase, respectively, the total length of the support element.
摘要翻译： 一种用于帮助卸载支撑元件的装置，所述支撑元件包括下轴和可伸缩地彼此联接的上轴。 该装置包括彼此同轴耦合的环形第一和第二主体。 每个环形体设置有允许上轴延伸通过通孔的通孔。 上轴也由第一环形体使用横向延伸构件支撑。 第二环形体位于下轴上。 中间卸载楔定位在联接在一起的第一和第二环形体之间，并且能够相对于其横向地滑动。 卸载楔的滑动导致第一环形体和第二环形体在纵向方向上聚集或移动分开，并因此分别减小或增加支撑元件的总长度。
