predetermined dimensions and lifting points of fixed beams. Larger spans are also possible, while systems can be disassembled and reconfigured to provide a different span as requirements change.
Distributor capacity In terms of capacity, today’s standard ranges might extend to around 400t. However, larger systems have been quoted, even if these have yet to result in orders. They nevertheless demonstrate the direction of travel. Just a few weeks ago, for example, a 1,000t system was proposed through one of our distributors in Florida to an aerospace company focused on developing technologies and infrastructure for spaceflight. That flexibility also has implications for the
distributor supply chain. Channel partners do not need to commit to large quantities of complete modular spreader beams or hold an extensive inventory of every possible configuration. Instead, they can respond to specific customer requirements as they arise, assembling or ordering the configuration needed for the job without tying up capital in stock that may sit on the shelf.
For instance, an end user might have an 18t lift scheduled for the following week and require a beam with 22ft between the pick points. Rather than having to purchase a range of fixed beams in anticipation of such requirements, the dealer can supply the precise configuration needed for that lift. This ability to buy according to demand, rather than in large-volume quantities, is a significant attraction of the modular concept for the supply chain.
Stocking for demand Since its launch around six or seven years ago, Dura-Mod has evolved in response to growing demand for quickly available components. A significant proportion of requests for quotations (RFQs) involve relatively short lead times, meaning the ability to react quickly can be critical to securing the order. This has driven an expansion of inventory to ensure the required components can be shipped without delay, while the modular concept also provides advantages in transport and storage. Components shorter than 14ft can be palletised with other components to allow a more condensed footprint for shipping, and the relatively compact nature of the system reduces the space required for inventory. Notably, at our Rockford, Illinois facility, many of the shorter components are stored vertically to further maximise available storage capacity. End-use applications continue to demonstrate the range of ways in which contractors are using the system. Two recent shipments went to different contractors, with one supplying a specific lifting solution at a museum construction project; and the other sourcing for inventory, ready to be configured and used as requirements arise. For distributors and end users alike, the

ability to hold a selection of components rather than complete beams means equipment can be assembled around a particular purpose when needed, supporting both responsiveness and efficient inventory management. For users specifying a Dura-Mod system, the starting points are relatively straightforward: lifting capacity and overall span. From there, the load charts identify the individual components required to create the appropriate configuration. Future development is focused on increasing capacities, finalising the corresponding designs and expanding stock accordingly. The company
has already increased Dura-Mod inventory, with growth expected as higher-capacity systems come through the pipeline. All Dura-Mod spreaders conform to the American Society of Mechanical Engineers (ASME) B30.20 and BTH-1 Design Category B, Class 0. Each modular system is manufactured in-house and is provided with a ‘Made in the USA’ badge. It is not advisable that the Dura- Mod concept is used in conjunction with other renowned manufacturers’ products in the same rigging system, even if components are certified and conform to relevant standards.
Modular spreader beams use compression to transfer load through the beam and its connections.
