Abstract: A carriage (50) for a wall saw that includes a saw head and a motor-driven feed unit with a guide slide and a feed motor. The carriage is made up of a base frame (51) with a supporting frame (55) and a receiving plate (56), a guide frame (52) with a handle (58), and a chassis (53) with a first axle (64), a second axle (66), and at least three wheels (65, 67). At least one wheel (65) of the chassis (53) is designed to be connectable to a gearwheel (45) of the guide slide (26) in a force- and torque-transmitting manner with the aid of a connection device.
Abstract: A setting tool for driving fastening elements in a constructional component, includes a muzzle (14), a bolt guide (15) located in the muzzle (14), a magazine (20) for fastening elements (50) and releasably mountable on the tool housing (11) and having a connection section (21) provided at an end of the magazine (20) adjacent to the muzzle (14) and with which the magazine (20) is secured to the muzzle (14), and a connection device for releasably mounting the magazine on the tool housing (11) and including a hinge bearing formed as a plug-in coupling and provided with a first support element arranged on the connection section (21) of the magazine (20) and a second support element arranged on the muzzle (14), with the hinge bearing (17) having a pivot axis (S) provided on a side of the magazine (20) remote from the housing (11), outside of the magazine (20) and outside of the muzzle (14) and extending at a right angle to a plane (E) defined by the bolt guide (15) and the magazine (20).

Abstract: A mounting construction (1) for suspended loads (L) has a support connector part (3, 3?) with a fastener device having a pivot element socket (4) and having an associated pivot nut (5), pivotably fixable in at least one pivot plane (1a, 1b), having an inside thread (6). The pivot element socket (4) has a guide slot (8) along a first pivot plane (1b) having a width (B) corresponding to a cross-section of a threaded rod (7) capable of passing therethrough. The pivot nut (5) and a marginal zone (9) arranged on both sides of the guide slot (8) each form guide surfaces (10a, 10b) that are saddle shaped.
