factory and machinery moves for lighter and sensitive processing equipment. “Strengthening and positioning ourselves in the market of heavy and complex lifting techniques is the fact that RRS Group is the sole agent for Hydra-Slide in the UK and Europe, which designs low profile, hydraulic skidding systems, used in many situations such as transformer moves, boiler moves in plant rooms, paper mill process plant, power and energy sector projects, oil, gas and sub-sea manufacturing machinery and even in food and beverage machinery installation where access and height are restricted,” says Claire Mellows, group business development director, RRS. “Hydra-Slide is represented by the RRS
Group and their key contacts at Hydra- Slide, headed by their CEO Janine Smith. The Hydra-Slide system is designed around the user and the requirement to offer function and convenience whether for confined space or just a much safer method than traditional load-moving equipment saving time, risk and money. RRS Group offers hire of, sales of or training on this incredibly versatile skidding system which we’ve been using ourselves for many years on many successful projects.” Dynamic Load Monitoring (DLM) based in Southampton, UK, also exhibiting at LiftEx, is a specialist in the design, manufacture, repair, and calibration of load cells, load monitoring, and cable working equipment for the offshore, renewable energy, marine, subsea, and lifting and rigging industries. It recently customised wireless load pins
for installation in winches supplied by Atlas Winch & Hoist Services (Southern) for cable pulling applications in the construction of offshore wind turbines. It supplied load pins for installation by
Atlas in various capacity capstans, which work in tandem with hydraulic power units (HPUs). The “load pin winches” are

typically purchased by Atlas’s clients for long-term use. “Atlas uses our load pins in their winches for this important end-use application, but we have collaborated on several projects over the years, and we also manufacture force measurement solutions for other projects in this fast-paced industry. We supply the load pins ready- machined; they just need to be installed in the winch mount point,” said Martin Halford, managing director, DLM. When constructed, the power generated
by a turbine is transmitted to an offshore substation before then going to the mainland. This requires miles of subsea cabling, and the final stage of pulling cables into the foundation of each turbine or to the substation is completed by special winching equipment and, here, a load monitoring system is provided via the load pins. According to Anton Lavery, MD, Atlas, the
final section of each cable - approx. the last 200m - is pulled from a vessel into the base foundation of a turbine or to the platform of an offshore substation. The electrical cable is high specification and high value, and it is therefore important to monitor the load applied during the pulling process. “A spike in the load applied might
indicate a problem and it is also important the cable installers can demonstrate and
prove the cable has not been over-strained during installation. Cables have a maximum load that they can be exposed to and if this is exceeded the cable warranty will be invalidated,” he said. Historically, Atlas has produced several 6t capacity capstan winches and HPUs, having originally provided them for a client called Cwind in 2014. Last year, it supplied a larger, 9t unit to a client before taking an order for a further eight of the same capacity. Atlas has since designed 11t and 12t capstans, which follow the same design concept, incorporating load pins. The winches and HPUs are produced by its manufacturing partner, Marotechniek, based in The Netherlands. When Atlas places an order, the load
pins are designed by DLM’s engineering team using in-house SolidWorks and other computer-aided design (CAD) modelling software, at which point the client can sign- off on technical drawings. The pins are then machined from stainless steel using a computer numerical control (CNC) lathe at DLM’s sister company, Vulcan Offshore. Once a load pin returns to DLM, it is ready for the strain gauging process, which is a “very intricate and delicate process,” explains Halford. Next, DLM builds the TW-3.0 transmitter
