An anchor windlass cable lifter pulls chain that surges with every wave — tension spikes as the vessel pitches, then slackens, then spikes again. The drive has to absorb it all at very low speed.

Motor roles in this machine

• JMDG — chain wheel drive: Crank-type radial piston construction handles tens of thousands of newton-metres with the mechanical margin marine class societies expect. JMDG reference →
• Surge tolerance: Smooth torque delivery from 3 r/min rides through tension spikes without shock-loading the chain or gypsy wheel.
