    The Knowledge: Lift beams pros and cons

    2015-06-08T16:23:00

    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: Spreader bar design and application

    2015-05-11T11:58:00

    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 Knowledge: Unloading dolly loads

    2014-11-17T15:42:00

    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

    Weighing continued: finding the co-ordinates

    2014-08-08T09:45:00

    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
