PCT No. PCT/EP93/03509 Sec. 371 Date Apr. 26, 1995 Sec. 102(e) Date Apr. 26, 1995 PCT Filed Dec. 11, 1993 PCT Pub. No. WO94/15115 PCT Pub. Date Jul. 7, 1994.The invention relates to a multi-stage reversing gear (1) that is changeable under load, especially as used in construction machines. The gear has a four-speed transmission (3) preferably fitted downstream of a changing set (2). The gear ratios can be changed via synchronous clutches (24, 25). To achieve compact construction, idler gears (11, 12) of the changing set (2) permanently engage with a fixed gear (14) of the transmission (3). The fixed gear (14) is fitted on a countershaft (15). The drive pinions (16, 17 or 20, 21) of the gear ratios are arranged to the left and right of the fixed gear (14) in relation to the longitudinal section of the reversing gear (1).
