Stothert & Pitt

Stothert & Pitt was a Bath-based British engineering company whose name became closely associated with large industrial cranes and port-handling equipment. The business grew out of the Stothert family’s ironmongery and foundry activities in the West of England. George Stothert had established an ironmongery presence in Bath in the late eighteenth century, and the family later developed foundry operations serving domestic, transport and industrial customers. Robert Pitt, who had trained and worked within the Stothert engineering network, became a partner in the 1840s. The partnership adopted the name Stothert and Pitt in 1855, establishing the identity under which the company became widely known. During the nineteenth century the firm expanded from general ironwork into substantial engineering projects. Its activities included railway equipment, bridges, engines, shipbuilding-related work, domestic cast-iron goods and cranes. The company’s Newark Street Works and later Victoria Works in Bath provided the manufacturing base for a rapidly developing business. Stothert & Pitt’s crane expertise became particularly important as ports and harbour authorities sought more powerful and mobile equipment for breakwater construction, cargo handling and shipbuilding. A Titan crane supplied for the construction of the Manora Point breakwater at Karachi in 1869 helped demonstrate the company’s ability to build heavy lifting machinery for international infrastructure projects. Further work included steam cranes, block-setting cranes and equipment for harbours including Bristol, Colombo and other imperial and overseas locations. The company was an early participant in the transition from steam and hydraulic systems to electrically powered dock machinery. It supplied an electric crane to Southampton Dock Authority in 1892. Electric drive allowed cranes to move along dockside rails, position themselves beside individual ship holds and operate without waiting for a boiler to raise steam. This development helped make mobile portal cranes a standard feature of modern ports. Stothert & Pitt also developed specialised lifting systems. In 1912, a design team led by Claude Topliss produced an improved level-luffing mechanism that helped keep a load level while the jib moved, improving handling speed and control. In 1927 the company built an early bulk-handling crane using an integral grab for unloading coal at a London power station. Its later kangaroo cranes incorporated a hopper beneath the jib, reducing the need for separate slewing movements during bulk-material transfer. Although cranes remained central, Stothert & Pitt diversified substantially. Its construction-equipment range included pedestrian rollers, concrete mixers, batching plants and tarmacadam equipment. By 1974 the company had manufactured 30,000 single-drum pedestrian rollers. It also produced railway breakdown cranes, ship cranes, offshore-platform cranes, lifeboat davits, winches, scissor lifts and other specialist machinery. During the First World War it briefly undertook military vehicle work, including construction of the pedrail machine chassis. During the Second World War it became an important armaments manufacturer, producing tanks, miniature submarines and naval cranes. Its work on the Challenger tank and related armoured-vehicle designs illustrated the breadth of its wartime engineering role, although those vehicle designs had significant practical limitations. The company’s corporate history became increasingly unsettled in the late twentieth century. It was sold to Robert Maxwell’s Hollis Group in 1986. After Maxwell’s business empire collapsed, a management buyout was attempted in 1988 but did not succeed. The company closed its works in 1989. Its name and intellectual property were acquired by NEI and incorporated into the Clarke Chapman group. Clarke Chapman subsequently became part of Rolls-Royce, and in 2000 the Clarke Chapman business was sold to Langley Holdings. The original manufacturing company no longer operates as an independent producer, but successor interests have continued to provide spares and aftermarket support for some Stothert & Pitt dockside and offshore cranes. The former Newark Works in Bath is a listed industrial building. After the closure of the engineering works, parts of the former site were incorporated into wider Bath redevelopment projects. Newark Works was later adapted for offices, small businesses and creative or technology-oriented enterprises. The surviving cranes, archival material and restored machinery remain significant reminders of Bath’s industrial history and of the company’s contribution to the development of mechanised port handling.

Stothert & Pitt developed from a wider family and partnership network of West Country ironmongers, foundries and engineering works. George Stothert moved to Bath in 1785 and took over Thomas Harris’s ironmonger business. He acted as an agent for the Coalbrookdale Iron Company, selling domestic iron products and other ironmongery. After Coalbrookdale opened its own Bristol warehouse, the Stotherts established their own foundry around 1815. The Bath business was subsequently managed by George Stothert’s son and expanded into manufactured ironwork. The family’s activities were linked to engineering enterprises in Bristol. In 1837 Henry Stothert established an ironworks that later became Stothert, Slaughter & Co. That business produced bridges, railway engines and ships. Robert Pitt joined this industrial network after serving as an apprentice with Stothert in Bath from 1834 to 1840 and working as a draughtsman in Bristol. He returned to Bath while the Newark Street Foundry was being established, and in 1844 became a partner with the Stotherts and another partner named Rayno. Although the partnership was often referred to simply as Stotherts, it became Stothert and Pitt in 1855. The business was incorporated in stages during the late nineteenth and early twentieth centuries. The Bath company moved from earlier premises north of the River Avon to the Newark Street Works on the southern side. During the 1890s it developed the larger Victoria Works, occupying much of the valley between the river and the Lower Bristol Road. Its early work covered general castings, domestic ironmongery, bridges, engines and industrial machinery. The company’s exhibition of a hand crane at the Great Exhibition in 1851 reflected the direction in which its engineering capabilities were developing. By the second half of the nineteenth century, cranes had become its defining product. Stothert & Pitt supplied cranes for docks, quarries, breakwaters and other infrastructure projects. A surviving crane associated with the company at Carmarthen probably dates from about 1850, while an older identified Stothert & Pitt crane from the 1860s was built for lifting heavy loads at Box quarries. In 1869 the firm built a Titan crane for the Manora Point breakwater at Karachi. It later supplied a large Fairbairn steam crane for Bristol docks and equipment for Colombo Harbour Works. Such contracts established the firm as an exporter of heavy lifting machinery. The company was also involved in the development of electric dock cranes. Its early electric crane for Southampton in 1892 demonstrated the operational advantages of distributed electric motors and rail-mounted mobility. Compared with fixed hydraulic cranes, mobile electric cranes could be moved along the quay and positioned at different ship holds. This allowed ports to use berths more flexibly and contributed to the widespread adoption of electric portal cranes. Stothert & Pitt later built specialised Goliath, shipyard, offshore and bulk-handling cranes. In 1912 the company’s design team, under Claude Topliss, improved level-luffing technology. The mechanism used compensating cable arrangements to reduce changes in hook height while the jib moved, helping operators handle cargo more quickly and accurately. In 1927 Stothert & Pitt produced an early bulk-handling crane with an integral grab for unloading coal. The company also developed the kangaroo crane, in which a hopper was integrated beneath the jib so that bulk material could be discharged without the same degree of slewing required by conventional arrangements. The two world wars broadened the company’s activities. In 1915 it took over production of the pedrail machine, a proposed armoured vehicle using unusual continuous tracks. The project was later considered for use as a mobile flame-thrower but did not proceed beyond limited development. During the Second World War Stothert & Pitt manufactured tanks, miniature submarines and other armaments, and supplied the Royal Navy with cranes for recovering reconnaissance aircraft from the water. It also worked on the Challenger tank and related designs based on the Cromwell chassis. Although the firm was highly experienced in mechanical engineering, armoured-vehicle design was less familiar territory and the Challenger’s tall turret made the vehicle vulnerable. After the war, Stothert & Pitt continued producing cranes and construction equipment. Its catalogue included pedestrian rollers, concrete mixers, batching plants, tarmacadam machinery, railway breakdown cranes, ship cranes, lifeboat davits, winches, scissor lifts and offshore-platform cranes. By 1974 it had produced 30,000 single-drum pedestrian rollers. The company remained an important Bath employer and industrial presence, but changing markets and ownership instability weakened the business. The firm was sold to Robert Maxwell’s Hollis Group in 1986. Following the collapse of Maxwell’s wider business empire, a management buyout was attempted in 1988. That effort failed, and the works closed in 1989. NEI acquired the business and transferred the name and intellectual property into the Clarke Chapman group. Clarke Chapman later became part of Rolls-Royce, before being sold to Langley Holdings in 2000. The original company is defunct, although successor operations have provided parts and aftermarket support for some surviving cranes. Stothert & Pitt’s former Newark Works is now a listed industrial building and has been incorporated into Bath’s urban regeneration. The site has been reused as flexible workspace and a business or creative hub. Preserved cranes, including examples displayed in Bristol and elsewhere, and the restored quarry crane returned to Newark Works in 2023, provide material evidence of the company’s role in the history of British heavy engineering and modern port mechanisation.
