Abstract: A mining machine haulage transmission includes an overload protection arrangement comprising a torque sensing device which monitors the torque transmitted and brings about decoupling of one or more clutches to disconnect the transmission output from its input, in the event that the transmitted torque exceeds a predetermined threshold.In one preferred arrangement, the torque sensing device produces electrical output signals dependent upon the transmitted torque to control operation of the clutch or clutches. In an alternative arrangement or in addition, a source of motive power is connectible to operate the clutch or clutches and control means are provided, responsive to the torque sensing device, to control connection of the power source to the clutch or clutches so as to bring about decoupling in the event of a torque overload.
