The invention discloses a suspension-type slewing and luffing device of self-moving crushing equipment for mining. The suspension-type slewing and luffing device mainly comprises a slewing unit and a luffing unit. The suspension-type slewing and luffing device is characterized in that all suspension-type slewing luffing device assemblies but a slewing driving device are hung and connected to a lower part of a cantilever of an equipment frame only by an outer tooth-type slewing bearing and all loads of all the suspension-type slewing luffing device assemblies but the slewing driving device are born by the only suspension connection; a hanging rack of the luffing unit is an n-shaped rigid structure composed of a flange and two side arms; hydraulic cylinders are located at two sides of a material discharge arm; and two end hinge joint points of each one of the hydraulic cylinders are located below a lower plane of the cantilever of the equipment frame. The suspension-type slewing and luffing device has a simple and compact structure. Through use of the suspension-type slewing and luffing device, the self-moving crushing equipment has a simple integral structure, light weight, a low gravity center and good stability.
