ABSTRACT:
There is disclosed a portable apparatus (10) for measuring relative coefficients of friction of a cnoveyor belt (12) or other work surface. A rounded contact shoe (38) contacts the surface while suspended between two flanking wheels (18,20). The shoe (38) forms one end of a lever arm (68) which is variably spring loaded at the opposite end to constantly urge the shoe (38) into contact with the moving test surface (42). The relative resistance is measured by a detector means, such as a load cell or strain gage (44) mounted in connection with the lever arm (68).
