Abstract
A boom collar for an outer telescopic boom section of a telescopic boom includes a tension belt forming at least a bottom surface and first and second curved corner portions of the collar. First and second sliders are disposed in the first and second curved corner portions, respectively, and the first and second sliders translate along the tension belt about a longitudinal axis of the said telescopic boom. First and second webs are connected to either side of the tension belt, and prevent the first and second sliders from moving in a direction of the longitudinal axis.
