Safety and Comfort

Safety and comfort for the operator translate into productivity on the jobsite, and Morooka carriers are designed with this fact in mind. All are equipped with a ROPS-certified canopy or cab and easy-to-operate controls. Climate-controlled cabs are standard on the larger models, and all feature a comfortable seat to fight operator fatigue.


Easy Maintenance

The full Morooka carrier line is designed with easy access to key service areas for ease of maintenance. This is accomplished by providing multiple access points for both the diesel engine and hydraulic components. Additionally, the simple design of the travel system contributes to overall durability as well as simplified maintenance. Parts and aftermarket support are also conveniently available from our various locations in the USA, from our parts company, Dominion Equipment Parts.



Hydrostatic Transmission

The hydrostatic transmission (HST) used in the Morooka carrier line accesses the engine’s full power more efficiently. The HST was chosen for Morooka carriers rather than a shifted gear transmission for its “stepless” change in speed ratio. Gear transmissions, whose working range is determined by torque and gearing, have a limited working speed range in challenging conditions.
