ABSTRACT:
A trolley for moving along a mono-rail track comprising two superimposed tubes, the trolley being provided with means for carrying a target, and being further provided with pairs of drive wheels which are inwardly inclined to rest on upper parts of the lower tube forming the track, the pairs of drive wheels having a "V" configuration. Additional pairs of substantially horizontal wheels engage opposite sides of the lower tube below the drive wheels. The drive wheels are driven by individual hydraulic motors, connected in series, and the hydraulic circuit for controlling the motors can be operated to achieve a braking effect on the wheels. Jockey wheels engage the top tube of the track. An additional spring pressure applied, hydraulic pressure released brake acts on the upper tube.
