Abstract: The excavator tooth has a tooth holder (1) on one end of which a wedge-shaped tooth nose (3) is developed. The tooth nose (3) bears a wedge-shaped tooth cap (5) in which a wedge-shaped hollow space (24) is recessed. With the tooth cap (5) mounted, the hollow space (24) is pushed over the tooth nose (3), which thus supports the tooth cap (5). For a good support, the wedge surfaces (8, 9) of the tooth nose (3) have radii of curvature curved convexly perpendicular to the longitudinal axis (16) and continuously decreasing from the tooth edge (7) to the nose root (17). In corresponding manner, the wedge surfaces (25, 26) of the hollow space (24) have concavely curved radii of curvature which continuously decrease from the base (28) to the mouth (29) of the hollow space (24). In this way a large application surface of the tooth cap (5) on the tooth nose (3) is obtained.

Abstract: In order to connect two tubular guide rails, a connector is used. Each tubular guide rail is formed with an elongate rounded recess which extends perpendicular to the longitudinal axis of the tubular guide rail. A seal member of elastic material is to be put between terminal ends of the two tubular guide rails. A joint plate has two parallel elongate rounded recesses formed therein. The joint plate is connectable to the two tubular guide rails in such a manner that each of the parallel elongate rounded recesses mates with the elongate rounded recess of the corresponding tubular guide rail to define a substantially cylindrical pin receiving space. Two cylindrical positioning pins are employed each being to be received in the substantially cylindrical pin receiving space. A securing device is employed which, when actuated, gradually presses the joint plate against the tubular guide rails and finally secures the joint plate to the tubular guide rails.
