SANY heavy machinery—especially excavators and cranes—dominates global construction sites due to its relentless power. But when the concrete gets tough or the mining environment gets extreme, the stress falls directly on one critical system: The Hydraulic System.
Welcome to the premier blog by ARCHER dedicated to supporting your SANY fleet. Today, Wayne shares essential insights on maintaining and sourcing SANY hydraulic components to keep your machines operating at 100% capacity.
Key SANY Hydraulic Components & Wear Prevention
1. Main Hydraulic Pumps
Whether your machine runs on a Kawasaki system or SANY’s customized inline pumps, the pistons and cylinder blocks must handle high-speed friction. Always check for internal case drainage flow during routine maintenance to spot internal wear early.
2. Final Drives & Travel Motors
The final drive takes the most abuse in muddy or rocky terrains. Mud pack accumulation can breach the floating seals, leading to gear oil leaks and catastrophic planetary gear failure.
3. Main Control Valves (MCV)
Spool sticking is the number one cause of erratic excavator arm movement. High-purity hydraulic filtration is mandatory to keep the tight valve clearances functional.

How ARCHER Guarantees Zero-Error Sourcing
SANY machinery has gone through multiple technical updates across different generations. Ordering by the machine model alone is dangerous.
