Lifting Device and Method for Lifting Brittle Elements
A lifting device for brittle elements such as bridge beam and deck elements, panels and the like up to and beyond 1,000 tonnes is described. The lifting device may be suitable for face and edge lifting of brittle elements that have a suitable cavity formed within or through them. The lifting device may include a lifting eye connected to an elongate member/shank that has a flared end. A sleeve about the shank may be used to raise and lower the moveably attached wedges to and from the flared end. In use the wedges upon the flared end prevent the withdrawal of the lifting device from the cavity of the brittle element. A cavity former is also described that may be used in the casting of the brittle element to form a suitable cavity.
