An electro-mechanical precision machined fabrication totaling 8.08m/26.5' in height. Bassett Defence Services manufactured 12 hoists in batches of 3 over a period of 8 years. They were manufactured in 9 separate sections, assembled and rigorously tested before being packed and shipped to dockyards to be commissioned by our own engineers to various Type 23 frigates including HMS Cornwall, HMS Sheffield, HMS Montrose and HMS Westminster. We assembled the hoist on site, conducted rigorous testing, took part in the sea trials and were responsible for a two year service programme.

The MK.8 hoist is an endless chain type, constructed as a rectangular steel trunking containing two vertical brass tubes of different diameters. The entire construction when complete undergoes water tightness and gas tightness tests for crew safety and battle readiness.

There are approximately 1500 line item parts, over 80 metres of welding, many different materials both special and standard and several kilometres of wiring included in this single assembly.
