Height legs: 2700mm, BA-030H is a semiautomatic attachment for spreaders, designed to handle overheight containers, flat-racks and platforms. TEC’s model is a universal frame which can be attached to any ISO spreader without the need of modification. The twistlocks open and close by means of a semiautomatic mechanism which is actuated by the movement up and down of the master spreader, but only when the landing pins are totally introduced into the legs.
