JMV53

Jeil JMV53 — two-speed track drive motor 53 cm³

Jeil JMV53 (JMV053) is a two-speed axial piston hydraulic track drive motor with an integrated planetary gearbox, manufactured by Jeil Hydraulics (South Korea). The numbers after the slash in the designation (JMV-53/34, JMV-53/31) indicate the minimum displacement in high-speed mode; the maximum displacement of 53 cm³ corresponds to the low-speed / high-torque mode. Automatic switching between modes provides the optimum balance of tractive effort and travel speed depending on driving conditions. Typical frame size for mini excavators in the 6–8 tonne class.
