    摘要: A gearbox (BV) comprises a secondary shaft (AS) provided with a synchromesh (SB) comprising a flange (FL) comprising a sub-hub (SM) fixedly secured to the secondary shaft (AS) and provided with external splines (CE3), a hub (MO) comprising internal splines (CI1) collaborating with the external splines (CE3) of the sub-hub (SM) to allow translational movement with respect to the latter (SM), and a sleeve (MA) that can undergo a translational movement with respect to the hub (MO) so that the internal splines (CI2) thereof are closely coupled to dogs (CR) of an idling pinion (PF1). This translational movement of the hub (MO) with respect to the sub-hub (SM) guarantees close coupling of the internal splines (CI2) of the sleeve (MA) with the dogs (CR) with a minimal margin for translation, irrespective of dimensional variations in the manufacture of the sleeve (MA) and idling pinion (PF1).

    摘要: An I-beam anchor for removably securing a fall protection member to an I-beam is disclosed. The I-beam anchor comprises a cross-beam, an anchor ring, and first and second brackets. The first bracket is positioned between a first end and center portion of the cross-beam and the second bracket positioned between a second end and center portion of the cross-beam. Each of the brackets comprises an inwardly directed flange spaced above the body of the brackets. At least the first bracket is a movable bracket and is movable along the cross-beam relative to the second bracket. The moveable bracket comprises a protected “quick release” mechanism that allows for the rapid engagement and disengagement of the anchor to the I-beam, in which the quick release mechanism is configured to minimize the chance of accidental or unintentional release.
