Nabtesco GM07 — axial piston hydraulic travel motor
Nabtesco GM07 is a travel motor from the GM series for small-class excavators. The hydraulic motor, planetary gearbox and parking brake are assembled in a single compact housing. The two-speed mode allows switching between working and travel speed without stopping the machine. Also marketed under the Teijin Seiki and Hy-Dash brands — all three names refer to a structurally identical unit. The Doosan Mottrol equivalent is TM07VC. Used as the travel drive on 5–7 tonne crawler excavators by Hyundai, Daewoo, Doosan, Volvo, Kobelco and Komatsu.
