Sheer-Legs, Thornbush Quay, Inverness

Probably 1909 erected by Rose Street Foundry Co Ltd.

This apparatus consists of a pair of angled front stays each

about 12m long, with the lower ends pivoted on the quay edge,

5.5m apart, and brought together at their upper ends with

a back stay of greater length but of similar riveted steel

construction. The lower end of the back stay can be moved

along a screw to incline the front stays over the quay

wall. A hoist, powered by the same motor as the screw, is

used to raise and lower a pulley block with a hook capable

of lifting 25 tons. The electrically driven mechanisms are

housed in a small corrugated-iron hut.
