Abstract
The invention provides an elongated pull element (14), in particular for an element of an expandable heavy equipment (1) comprises a bundle of load bearing fibres (41) extending along the length of the elongated pull element (14), and stiffening means (54) comprising an exoskeleton comprising at least one rod outside of the fibres, for increasing the bending stiffness of the elongated pull element (14), compared to the bending stiffness of the load bearing fibres (41). Through this configuration the invention provides a reduction in the weight of the expandable heavy equipment
