\nFive Core Product Advantages
\n1. Integrated box design, simplifying the oil circuit to prevent oil leakage.
\nThe valve block can be directly fixed to the hydraulicoil tank, eliminating the need for external return oilpipelines, reducing joint leakage points, keeping thechassis clean, and lowering the probability of oilleakage failures
\n2. Safer than the slow-down function and unloading
\nEquipped with the cab air control handle, it allowsstepless adjustment of the cabin’s descent speedslow removal of heavy-duty sand and debris from thecabin, and prevents sudden drops that could damagethe frame and cylinders.
\n3. Built-in overflow safety valve, protective hydraulic system
\nIt is equipped with an adjustable pressure relief valve,automatic overload relief, preventing excessive liftingpressure from damaging the cylinder, oil pipes, andpower take-off, thereby extending the service life ofthe entire hydraulic component.
\n4. High-strength cast aluminum valve body, impact-resistant and corrosion-resistant
\nThe precision cast aluminum valve body is equippedwith imported oil-resistant rubber seals, constructionsite mud and water resistance, corrosion and agingresistance in high-temperature environments, and nooil leakage during long-term high-pressure operation<\/p>\n
5. Direct replacement of oil hole positions and damageat the plant fully aligns with Haiwo’s original factorydimensions, provides accurate matching of oil and gascontrol interfaces, repair shop does not requiremodification of the oil circuit, offers fast disassemblyand assembly, and is compatible with most front-topself-unloading hydraulic systems
\nFault Replacement Indication1. The lifting of the box is weak, the lifting isslow, and it is completely impossible to lift.2. The mid-stop lock fails, the carriageautomatically slides down, and the bucketslides down3. The compartment speed is out of control,cannot slow down, and the impact is excessive4. Oil leakage from valve body joints andinterfaces, and unstable oil pressureestablishment5. Relief valve effect, frequent oil pipe bursts,and abnormal noise in hydraulic pipelines<\/p>","protected":false},"excerpt":{"rendered":"
