Z-Drive Type Applications for Main Propulsion

 

Ports worldwide are requiring Tugs and Escort Vessels
to handle larger ships within smaller, less maneuverable areas.

Logan CH Series clutches are ideal for stern drive tugs and work boats that require high torque transmission from a multiple disc wet or dry clutch - within a small envelope.

Dependability, reliability, ease of operation and maintenance are what make Logan CH Series the clutch of choice for Maritime propulsion.
