Boat lift

nounStandard termMechanical

A mechanical elevator system that transports vessels vertically between different water elevations.

A massive mechanical structure used on navigable waterways to raise and lower boats directly between two different elevations, bypassing the need for a series of traditional locks. The system typically uses water-filled caissons suspended by cables and counterweights or supported by hydraulic rams. It drastically reduces transit time and conserves the water that would otherwise be lost during conventional lock cycling.

Heard on the job

The hydraulic rams on the boat lift need their seals inspected before the summer navigation season begins.
