1 Hydraulic EquipmentFor Compact Construction MachinesSkid Steer LoaderStump CutterHorizontal Directional DrillUSING OUR COMPREHENSIVE CAPABILITIES, NACHI can meet your requirements in the diversifiedmarket of compact construction is a growing need for sophisticateddiverse compact construction machinery interms of function, productivity, maneuverability,and offers unique solution for this marketwith our pumps and to our extensive studies of piston motordesign, NACHI has succeeded in achievingpower efficiency, operational stability, andsubstantial downsizing of the our comprehensive capabilities, NACHI meets the needs of the world s market of compact construction Series Travel MotorFeatures All-in-One DesignAll required components for track drive motor are in one unit. (planetary gearbox, Hydraulic motor , negative type parking brake,shockless relief valve, anti-cavitation check valve, other optional valve.)

2 High ReliabilityAll main parts, including special-made angular ball bearing in gearbox, are made and tested by NACHI . High EfficiencyThe axial piston motor can maintain good efficiency at highpressure ranges. It reduces engine stall, and enables better machine maneuverability.
