and gas, subsea, engineering and fabrication, and papermaking. The Mactech Europe Air Operated Trip assembly has been introduced to offer safe remote operation of the feed trip pin combined with a two-handed start control. This ensures the operator has full control of the operation of the clamshell lathe while remaining outside the potentially hazardous zone. The start handle and the trip assembly use air taken from the main air supply to the clamshells pneumatic drive motor and no other power source is required. To start the machine the operator must use both hands; after start up, only one hand is needed to keep the machine running, leaving the other hand free to operate the control of the feed pin. If the operator releases the run control, the machine will come to a stop and the feed pin retracts automatically. The air operated trip assembly is a direct replacement for the manual version with no other modifications necessary.

Cellular beam bender BARNSHAW Section Benders has been involved in several large-scale energy and renewables projects. A recent job involved the company’s structural division working with ASD Westok and Fisher Engineering, which is a part of Severfield-Rowen plc. Both cellular beams and sections have taken the company’s expert benders 3 to 4 months to form, and together they weighed approximately 500 tonnes.

Barnshaws has a strong relationship with ASD Westok, and the early consultations enabled the client to see that Barnshaws was willing to invest heavily in order to meet its requirements. Barnshaws has invested more than £70,000 on new equipment and tooling, which means that the company can now curve the largest cellular beams available. Barnshaw Section Benders is based at six manufacturing sites around the UK, located in the West Midlands, Manchester, and Hamilton in Scotland.

Working together with ASD Westok, Barnshaws was asked to produce some of the deepest cellular beams ever requested, the largest being a 1,594mm deep beam formed from one of the biggest universal beam sections that Tata produces. The beams were not only large in terms of depth, but also in length, with upwards of 23m of bar to be curved. Barnshaws has also been curving a number of bars direct for Fisher Engineering, which includes a variety of sections and sizes ranging from 457mm deep universal beams to 400mm deep rectangular hollow section (RHS).
