At the 2025 Bauma Munich Exhibition, excavator travel motors became a highlight, with major brands showcasing innovative products. Liebherr launched the RE 25 M Litronic railroad excavator, equipped with a hydrostatic rail wheel drive motor. Its 120kW engine and unique hydraulic system enable it to switch between 9A and 9C driving modes, protecting rail infrastructure. With a 1.57m small tail swing radius, it meets safety standards in markets like France and is a game-changer in the 25-ton class.
Caterpillar unveiled the 395 FS front shovel excavator, set for mass production in October 2025. Its custom travel motor extends maintenance intervals by 30%, ideal for mining. The aftermarket 265-8751 final drive motor, pre-assembled and oil-filled, allows easy installation without core charges, fitting multiple mini excavator models.
Chinese brand Likchuan made waves with its closed-loop travel motor solution. Integrating dual-displacement axial piston motors and planetary reducers, it cuts energy loss by 15-20%, with 0.1r/min control precision. Certified by CE, it works stably at -40℃ and is 20-30% cheaper than international peers, suitable for mini excavators and agricultural machinery.
For troubleshooting, first check for abnormal noises or oil leaks. Weak startup with noise may indicate worn parts; oil leaks often stem from O-ring cracks. Use pressure tests: failed pressure rise points to relief valve issues; normal pressure but no startup means blocked brake circuits. Follow ISO standards for repairs: secure the machine, clean parts, replace O-rings, and run idle tests post-assembly.
