FIELD: transport.
SUBSTANCE: invention relates to device that drives transport facility. drive (10) comprises first hydraulic motor (12a) engaged with driven shaft (16), second hydraulic motor (12b) and connector (18). The latter comprises synchronizing body (20) with conical friction surface (22) engaged with second hydraulic motor (12b) and gear (24) with appropriate friction surface (26) displacing relative to said body (20) and engaged with driven shaft (16). Second hydraulic motor (12b) engaged with driven shaft (16) allows the possible difference in rpm between body (20) and gear (24) to be decreased. Friction fit between friction surface (22) of body (20) and friction surface (26) of gear (24) can be set by displacement of body (20) and gear (24) towards each other. After disengagement of second hydraulic motor (12b) from driven shaft (16), friction fit between friction surface (22) of body (20) and friction surface (26) of gear (24) can be terminated by displacement of body (20) and gear (24) towards each other.
EFFECT: compact design.
