A protection device for a rope saw assembly () includes at least two, telescopically displaceable relative to each other, cover members () having each a circular cross-section, an extending along a longitudinal axis receiving space () for the saw rope (), and a longitudinally extending opened slot (), and provided each with a securing device () located on one end () of each of the cover members () for securing a respective cover member () to a respective deflection roller () of the rope saw assembly ().

Protection device for a rope saw assembly

A deflection device for a rope saw assembly, includes a deflection roller (); a stationary protective cover () surrounding art least some regions of the deflection roller (); and at least one cover member () pivotally arranged on the protective cover () surrounding at least some regions of the deflection roller, and displaceable along a path radially spaced from the axle () of the deflection roller ().

Deflection device for a rope saw assembly

A device for deflecting a saw cable ( ) of a cable saw and having a support ( ) and at least one deflection member ( ) securable to the support ( ) and having two support arms ( ), between which a deflection roller ( ) is rotatably supported, and two guide surfaces ( ) formed in the region of the deflection member ( ) projecting beyond the deflection roller ( ) for preventing the saw cable ( ) from falling off of the deflection roller ( ).

Cable saw

An articulated lock for a saw rope (,) and including a first articulated member (,) having a sleeve-shaped region for receiving an end of the rope (,) and a connection region (,) formed of two, spaced from each other cheeks (,), a second articulated member (,) having a sleeve-shaped region for receiving another end of the rope (,), and a connection region (,) formed as an eye-shaped portion and extending into a space defined by the two cheeks (,) of the connection region of the first articulated member (,); and a joining bolt (,) extending through the bores (,) formed in the two cheeks (,) and the through-opening (,) formed in the eye-shaped portion for pivotally connecting the first and second articulated members (,) with each other, with the through-opening (,) of the eye-shaped portion having at least in a region of the opposite side surfaces (,) of the eye-shaped portion, a diameter exceeding the diameter of the joining bolt.
