4213017 Original Excavator Parts Clamp for ZX110-3

The fixture with part number 4213017 is a high-quality hydraulic accessory manufactured or certified by Hitachi, typically referring to hydraulic grippers or hydraulic fixtures. According to the Hitachi parts system, this fixture is widely compatible with medium to large crawler excavators in the Hitachi ZX and EX series, such as ZX200, ZX210, ZX240, ZX300, ZX330, ZX360, and corresponding common models such as EX200, EX220, EX300, etc

As an original hydraulic fixture, 4213017 adopts a main structure made of high-strength wear-resistant steel plates welded together. The key stress bearing parts are reinforced with ribs and locally quenched to withstand heavy loads and impacts. Its core function is driven by a hydraulic system, usually including one or more large capacity double acting oil cylinders to provide strong clamping force, and may integrate a hydraulic rotary motor to achieve 360 degree continuous rotation of the fixture, greatly improving operational flexibility and efficiency. The jaw plate (claw teeth) of the fixture is designed in various forms (such as multi tooth, plum blossom, shell) to adapt to the grasping of different materials (round wood, stones, scrap steel).

The maintenance core of this fixture lies in regular lubrication, hydraulic system maintenance, and structural inspection. Daily lubrication: Every 8-10 working hours or before each day's operation, all pin shafts, bushings, and rotating bearings must be filled with designated high-pressure lubricating grease until the old grease is squeezed out by the new grease. This is the key to preventing abnormal wear and jamming. Hydraulic system inspection: Regularly check all hydraulic oil pipes and joints for wear and leaks; There is no abnormal noise or delayed action when monitoring the operation of the rotary motor and oil cylinder, which may be a sign of internal wear or seal failure.
