The "drop gate" on this lift lock was a technological advance over the more common swing-gate lock. It was faster and could be more easily operated by a single employee.

Only a few drop-gates were installed on the canal, most of them to speed traffic here at Seven Locks where it often took boatmen an hour or more to lock through.
