Tower crane safety specialist Smie has unveiled an anti-collision device that provides safe work ing zones for firms with a large variety of equipment. The firm said it had modified the AC340 from its tower crane systems, which work in two dimensions, to provide a threedimensional safety 'envelope' for complex applications. The device enables the operator to see where the crane and its load are at any time with reference to all potentially obstructive machines.
