The computer optimizes the structural design,the tetrastyle is simple economy, practical;The frame posture structure uses gives the tight tension bar fuselage,the slide uses eight guide rails guidances rigidity well,the precision is high,anti-carries ability.The hydraulic control system uses inserts installs the valve integrative system and the fat liquor cooling system,the movement reliable,service life long,the hydraulic pressure impulse was small,reduces has connected the pipeline with to release the leaking point.The electrical system uses the PLC control the electrical system,the structure compact,the work keen is reliable;Black-white control system work reliable, movement direct-viewing,the service is convenient.Has the adjustment, the semiautomatic three technique.Through operation kneading board choice,not only may realize decides the regulation the constant pressure two kinds takes shape the craft,moreover the fluid pressure pad may realize jacks,is less effective,stretches three kind of crafts circulation.
