They are gearmotors particularly suitable for:

• Mini excavators
• Truck crane
• Aerial platforms
• Concrete pumps
• Other similar applications

TECHNICAL AND CONSTRUCTION FEATURES:

• n. 13 sizes for output torques up to 70,000Nm.
• pinion shaft outputs supported by bearings with large load capacity
• sturdy output body with high or low mounting flange
• inputs for different types of hydraulic or electric motors
• parking brakes, mounted at the input, of the multi-disc type in oil bath with negative action; hydraulic opening, closing by means of springs
• double action multi-disc brakes are available for mobile cranes: positive and negative, for dynamic and static braking with double hydraulic control
• oversized gears and bearings for very heavy duty
• available with hydraulic motors complete with maximum pressure and anti-cavitation valves

The unit consists of:

• High performance semi-integrated orbital motor
• Planetary gearbox with one or more reduction stages for a wide range of ratios
• Different types of output sprockets
• Control valves flanged on the engine, such as: anti-shock and anti-cavitation valves, balancing and anti-shock valves
• Internal control multidisc negative parking brake (optional)
• Separate motor-gearbox lubrication.
• Planetary reductions with shaved gears then cemented and hardened; crowns with tempered and induction hardened internal toothing
• Sturdy reducer body in ductile iron
• Shafts with integral or reported pinions obtained from forged steel, worked then case-hardened and tempered
• Shaft support bearings with large load capacity to withstand the high loads deriving from the pinion-fifth wheel meshing
• Lubrication in oil bath, lower bearing on the pinion side permanently lubricated with grease.

It is a series designed for the rotation of cranes and turrets, operating machines, wind power plants, drilling.
