Full hydraulic wheel trench compactors for backfilling the trench subgrade compaction. ◎ drum cam design to ensure compaction and climbing ability of the machine; ◎ electromagnetic clutch control vibration, easy and convenient operation; ◎ button controls hydraulic steering, flexible and convenient; ◎ using international cards bearing, belt, button, ensure that the machine stability; ◎ use of international brand-name variable piston pump and quantitative hydraulic motor, before walking speed is adjustable, convenient commutation; ◎ armrest storage can be erected to reduce transport space; has a "back" forced commutation lever makes the operation more security; ◎ surface spray, nice appearance, rust corrosion. The main technical parameters: Model JYCB-G635C walking speed 0-4m / h water tank capacity 26L gradeability 30% Hydraulic tank capacity 20L drive variable displacement piston pump powered models CF178F vibration control electromagnetic clutch power 6.0HP static linear load 55N / cm steel Wheel size 350 * 635 * 2 vibration spoke on behalf of 0.5mm package size 1510 * 870 * 1920 Net weight 780KG vibration frequency 70HZ exciting force 30KN Starting system Recoil / electric start small roller: Small roller working pressure was significantly higher than 11MPa Workaround : Work pressure was significantly higher than 11MPa, should remove the vibration motor, vibration bearing axial clearance check. The vibration of the shaft axially pushed seized, should be 1 ~ 2mm axial runout; then check the radial vibration bearing clearance, the radial force is applied to the eccentric shaft with a pry bar, if obviously feel runout shall In other bearings; finally check free movement of shaft vibration conditions, to the vibration of the shaft screw shaft mounted a hex head bolt, bolt 1900C rotate clockwise with a socket wrench, then loosen wrench. If the vibration when several swing freely, feel significant resistance, the incumbent bearings. If the vibration circuit starting pressure is low, you should remove the high pressure hose pump vibration on tubing sealed with a plug interface, 60MPa pressure gauge connected to the vibration of the pump high-pressure port, engine throttle lever to stop put out position. Turn the diesel engine starter motor, if the pressure is less than 10MPa replace the pump, if the pressure of 10MPa, check the starter control valve.
