    Introducing know-how


    An introduction to a new series of practical how-to articles that will appear regularly in IC. Marco van Daal contributes his extensive knowledge with a view to helping increase safety in heavy transport and lifting operations

    The knowledge with Marco van Daal: Transport types


    The second of ICST’s series of practical how-to articles aimed at improving safety in heavy transport and lifting operations

    The Knowledge: Cranes, a bit of history


    In the third article in our new how-to series, Marco van Daal turns his attention from transport to cranes with a historical perspective on developments in the lifting industry

  • Using air bag rollers to launch ships requires attention to be paid in tying it back

    The Knowledge: Alternative lifting


    As a sequel to the last two articles on transport and crane basics this month’s feature, the fourth in the series, covers alternative moving and lifting techniques. Marco van Daal explains some options

  • Strand jacks in operation being used for horizontal movement rather than vertical lifting

    The knowledge: Alternatives


    The previous article in this series covered alternative moving techniques, including rolling, skidding, airbags and air pallets. This time attention turns to some alternative lifting methods. Marco van Daal reports

  • Figure 1 is a two-dimensional object, for example, a steel plate with a random shape for which the C

    The Knowledge: Central focus


    A topic central in more ways than one both to lifting and transport operations is centre of gravity. CoG can be an issue that makes or breaks a project says Marco van Daal

  • Figure 1: A load cell with its connecting cable

    The Knowledge: Time to weigh


    Following on from and linked to the centre of gravity topic from last month’s article, is this month’s equally important subject of weighing a load. Marco van Daal reports

  • Figure 1

    Weighing continued: finding the co-ordinates


    As shown last month a weighing can be used to determine the X and Y co-ordinates of a load. When it comes to the Z co-ordinate, however, it can be a different matter, as Marco van Daal explains

  • In Figure 1 the LFP and the URP of the A-type turntable can be easily recognised. The lower chains h

    The Knowledge: Bolsters or turntables


    The topic this month in our regular how-to series is an explanation of bolsters or turntables and ways to implement them for transporting long loads. Marco van Daal reports

  • Figure 1

    The Knowledge: Dolly or not


    It is not always a straightforward decision when considering whether a load or a route is suitable for a dolly type transport. Marco van Daal reports

  • Transporting and lifting a 700 ton vessel in Qatar

    The Knowledge: Unloading dolly loads


    This article completes a series of three. We have seen what bolsters or turntables are and the various different types. Last month’s article highlighted some transport scenarios where things can go wrong if not assessed properly. Marco van Daal reports

  • Spreader bars and lift beams are most commonly used as a below the hook rigging tool to keep the low

    The Knowledge: Bars and beams


    In the first Anniversary article of our The Knowledge series, Marco van Daal examines spreader bars and lift beams used in rigging

  • The day the bullets came to town

    The Knowledge: Bullets on the move


    As a way of illustrating some of the skills and techniques described in previous Knowledge series articles, Marco van Daal presents a case study of a major moving project

  • Figure 1 shows a Modulift triple spreader bar arrangement

    The Knowledge: Spreader bar design and application


    Spreader bars are a versatile, below the hook, rigging tool so widely used that often the concept is forgotten or neglected in the design stage of it. Marco van Daal explains

  • Figure 1 shows the lifting of a nacelle for wind turbine

    The Knowledge: Lift beams pros and cons


    Earlier articles in this series have explained the differences between spreader bars and lift beams. Here Marco van Daal moves on to discuss the merits of the latter

    The Knowledge: Pull force


    In this technical article Marco van Daal provides a detailed explanation of a truck's pull force, why it is important and how to calculate the actual theoretical pull force

  • Mack Prime Mover (engine type E7-400)

    The Knowledge: A case study


    In his regular series of technical feature articles industry expert Marco van Daal provides a case study on pull force to determine suitability of prime movers for a particular task
