Application Scenarios

It serves as the oil storage unit of loader working hydraulic system, widely used in earthwork, quarry, sand yard, bulk cargo loading and other heavy-duty working conditions.

• Manufactured strictly according to OEM drawings, outline, mounting hole and oil port position fully match original parts, direct installation without modification.
• Thick steel plate welding structure, reinforced welding at stress points, good deformation resistance under vibration and impact of construction site.
• Built-in diversion baffle design, effectively suppress oil turbulence, separate air and precipitate solid impurities, reduce system cavitation.
• Complete standard reserved interfaces, compatible with original filter, breather, level gauge and drain assembly, convenient for maintenance.
• All welds are checked and pressure tested, high sealing performance, effectively prevent oil leakage and external dust and water intrusion.
• Double-layer anti-corrosion paint coating, strong adhesion, resist mud splashing and rusting in harsh outdoor environment.
• Reasonable overall layout, good heat dissipation effect, help control hydraulic oil temperature and reduce system overheating failure.

FAQ 

Q1: Can this hydraulic tank be used on other loader models?
A1: Part 252105036 is dedicated for ZL50G/ZL50GL. Other models differ in volume, hole layout and mounting size. Confirm part number before ordering.

Q2: What will happen if the hydraulic tank leaks oil?
A2: Oil leakage leads to insufficient oil supply, pump cavitation, unstable boom action, accelerated wear of hydraulic components, and even system shutdown. Replace gaskets or tank timely.

Q3: What checks should be done before installing a new hydraulic tank?
A3: Clean the tank interior thoroughly, check welds and gaskets for damage; confirm all ports are unblocked, then align mounting holes and fasten bolts evenly.

Q4: Why does the hydraulic oil overheat frequently?
A4: It may be caused by blocked radiator, insufficient oil volume, blocked return filter, internal baffle damage or excessive oil contamination. Check the tank and cooling circuit together.

Q5: Can we weld the leaking tank directly on site?
A5: Empty and clean the tank completely before welding to avoid fire risk. On-site welding will change internal stress; serious cracks are better replaced with new tank.

Q6: How to maintain the hydraulic oil tank daily?
A6: Check oil level from level gauge regularly; inspect welds and gaskets for leakage; keep the breather clean; clean or replace filter elements on schedule.
