Advantages
 

• During maneuvering – which requires reduction of main engine speed, the Logan PTO is used as a separate power source for bow and stern thrusters.

• The PTO directly connects to a pump drive, which powers winches, reels, hoists, and deck pressure washers.

• The PTO can be coupled to an alternator to supply electric power to other power consumers on the vessel.

Air-Fluid Actuated PTO SPF 1000

Note: The torque capacity of the clutch is directly proportional to the operating pressure. Maintaining the lowest pressure possible to transfer the desired torque will enable the clutch to run cooler and extend the life span of the internal bearings. The output end of the clutch (female spline/bore) is not capable of supporting any side load. Use overhung load adapters. Drive shaft alignment must be within 3 degrees. Maximum installation angle should be 7°.
