摘要： The present invention relates to a method of securing a shaft at any point along its substantially vertical axis of movement, wherein the method includes a locking device that is moveable with respect to the shaft. The method is characterised by the step of moving the locking device into a position wherein at least one face of the locking device mates against at least one point on the shaft so as to secure the shaft at any point along its substantially vertical axis of movement. In particular this invention relates to a method of securing a drop hammer at any point along its substantially vertical axis by use of a hydraulically controlled cam.

摘要： The invention relates to improvements to rock crushers, and in particular rotary impact rock crushers. The crushing chamber may be angled to achieve the desired rock product. Also disclosed is an anvil for use in a crusher whereby the anvil position is adjustable. The invention enables the operator to dial up a particular rock product specification by adjusting the angle of the crushing chamber and/or the position of the anvil. The adjustments may be made without ceasing the operation of the machine. Improved control over fracture mechanisms within the crushing chamber and as a consequence the rock product, are achievable with the present invention.

摘要： The present invention relates to a drive mechanism for a drop hammer, wherein the drive mechanism includes a translation dog adapted to engage with at least two projections provided on a drop hammer to move said drop hammer. The drop hammer includes a drive system to move the translation dog, which in turn engages a first projection provided on the drop hammer to translate the drop hammer in a first direction. When the translation dog releases the first projection, it then engages a separate drive projection provided on the drop hammer to translate the drop hammer in a second direction opposing said first direction.
