    The Knowledge: Performing the ro-ro


    This, the 32nd in our regular Knowledge series of how-to articles, puts the theory of how to perform a ro-ro operation into practice. Marco van Daal explains

    The Knowledge: Buoyancy and density


    Understanding buoyancy is important for anyone involved in roll-on and roll-off operations in the specialized transport sector. Marco van Daal explains it and the practical implications

  • Figure 1

    The Knowledge: Craning a crane


    In a slight departure from the usual theme of this technical series, Marco van Daal uses a case study to illustrate several of the principles and calculation methods explained in earlier articles

  • Figure 1 shows the forces that play on a freely suspended load

    The Knowledge: Around in the ground


    In the 21st article of his regular series, Marco van Daal takes a closer look at what goes on around and underneath a crane when lifting wind turbine components

  • When underestimated, the wind forces in combination with potential gusts and the short and rapid swa

    The Knowledge: A force to reckon with


    This month, Marco van Daal looks at the common dangers of erecting the latest generation of wind turbines and discusses ways to prevent wind associated accidents

    The Knowledge: The need for speed


    In his regular feature, this month Marco van Daal discusses how to determine power requirements for road transport

  • 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

    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

    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

  • 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

  • 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

  • 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 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

    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

  • 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

    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

  • 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 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

    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
