Automatic Electric Mooring Winch

Summary

When ship mooring, winch motor blocked turn, motor torque and rope load be balanced. At same time, if the rope pull smaller, motor shaft torque greater than load torque, forced motor forward rotate, tighten the cable, tension increased gradually until the moment balance.

If rope load become larger, the motor will be drag reverse rotate to produce resistance becomes brake, the resistance torque with sliding rate increases. The rope was pulled out, tension becomes small, motor slow down until it stops.

When winch automatic mooring, motor sensor 1-2 minutes at a constant tension to twist rope and adjust the tension.

Working Principle

The basic principle is winch drum applied a adjustable torque, in order to maintain a balance of mooring line tension caused by vessel moment. When ship due to change of draft or by tides, wind effects, leading to the mooring rope tension decreased to deviate from the prescribed value, automatic winch can accordingly automatic retractable cable, to stable tension to the specified value. In this way, can prevent the cable break, ensure mooring safety, and reduce the labor intensity and operating personnel on duty.
