    摘要: A dolly is provided for facilitating removal and installation of brake drums on vehicles. The dolly includes a frame having a cradle portion for supporting a brake drum. Wheels are rotatably mounted on the frame for moving the frame over a support surface into position beneath a brake drum. A handle projects from the frame for manually manipulating the frame into and out of position relative to the brake drum. An elevating linkage is provided for raising and lowering the frame relative to the wheels to lift and lower the brake drum relative to the vehicle.

    摘要: An automated apparatus for removing rivets connecting a brake lining to a brake shoe is provided. One aspect of the invention includes a frame structure to which a brake shoe support assembly containing a plurality of curved supports is attached through a spring biased guide means. The brake shoe support assembly is rotatable through use of a stepper motor so rows of rivets on the brake shoe can be aligned with the rivet punch bits of the apparatus. The punch bits are mounted in a punch block that is rigidly attached to the frame structure. The punch block contains at least one module that that can be moved transversely with respect to the brake shoe so that the punch bits in the punch block can be aligned with the different columns of rivets on the brake shoe. A press assembly pushes the brake shoe clamped to the brake shoe support assembly against the bias from the spring biased guide onto the punch block so that the rivets are removed. The apparatus is automated using a programmable control logic unit so that an operator only has to clamp the brake shoe onto the brake shoe support assembly and the apparatus completes deriveting the brake shoe.
