FIELD: transport.
SUBSTANCE: proposed test bench consists of the frame and conveyor belt strop secured thereon. Support devices for said strop represent two steel rope strips and inclined roller supports arranged across the belt. Ropes and roller supports are arranged horizontal flanges and slides pivoted together. Said flanges accommodate rollers with chutes to receive ropes. Suspension with additional horizontal flanges are secured to aforesaid flanges on the side of hinges to receive replaceable weights. Roller supports on the slides are mounted by means of hinge assemblies to vary and fix roller angle of inclination to horizon with the help of arc-like lateral guides with vertical cutouts and nuts to interact with axle threaded ends. Opposite ends of axles are located in guide sleeves of hinge assemblies to allow axles to displace axially therein on turning the nuts. Length of each roller is smaller than that of axles, while rollers in their initial position are arranged with minimum clearance relative to arc-like lateral guides. Flat limiters for carried cargo sample adjoin the belt strop chute on the side of its faces. Limiters are furnished with rolls and arranged to move along the frame. Both ends of belt and tope are secured on said limiters. Rope ends are connected to dynamometre for it to be moved with ropes along the frame.
EFFECT: simplified design.
