<b>Slings</b> Slings are devices that do not belong to the hoist and that establish a connection between the load-bearing means e.g. the load hook or grippers, crossbeams, tongs that are permanently connected to the crane. Establishing this connection is called "struck" and is carried out by so-called hunters. Safe cargo handling depends on his skills and abilities. Load handling devices are also not part of the lifting equipment, which can be connected to the lifting device to pick up the load. The load handling equipment includes e.g. container harnesses, hangers, grippers, clamps, buckets, lifting magnets, pallet harnesses, cross bars, vacuum lifters or even tongs. Load suspension devices can also be connected to the hoist by means of couplings that are designed for frequent loosening. The slings include chains, ropes (natural fiber, synthetic fiber and wire ropes) as well as lifting straps and lifting belt slings made of synthetic fiber fabric with and without wire insert. Round slings (a band or rope connected to an endless loop) are colloquially also called “smurf”, “strop” or “grummets”. The permissible load capacity (in kilograms or tons) must be stated on all lifting accessories and is internationally referred to as Working Load Limit (WLL). It results from the minimum breaking force of the MBL sling, multiplied by a load attachment factor LF. WLL = MBL * LF.
