HW60 breaststroke ramming machine type breaststroke ramming machine HW series breaststroke ramming machine 40 electric vibrating frog frog rammer tamping breaststroke ramming machine is the use of impact and shock vibration effect layered foundation backfill compaction machinery . Electric frog ram: the principle of a rotating inertia force is made by the rammer, tamping frame, eccentric, pulleys and motors and other components. Motor and transmission parts mounted on the skid base, tamping frame hinged rear end of the drive shaft in the eccentric centrifugal force, tamping frame can swing around this axis. Rammed the front frame fitted rammer, when the ram downward swing frame on soil compaction, so that sled seat forward swing upward. Therefore, frog rammer rammer once every impact, the body that is moving forward step. HW60 breaststroke ramming machine main technical parameters: compaction energy: 600N.m ram head up: 200-260mm forward speed: 8-13m / min tamp times: 140-150 times / min Motor power: 3KW frog ramming machine consists of motor, transmission, chassis, racks and electrical components ram, HW40 breaststroke ramming machine works by transmitting power to the front pulley mounted on the frame by ramming through a two-stage variable-speed motor, front pulley rotates drive Two eccentric mounted thereon rotary, centrifugal force, so that rammed head up, drop, loose soil compaction automatically advance. The breaststroke ramming compact structure, flexible operation, solid and strong, HW40 breaststroke ramming machine can be widely used in various types of housing, roads, water, bridges and other construction sites, as well as everything you need loose soil compaction earthworks.
