Screwlink connectors might be more appropriate than other types of connector for2.7.4.2 infrequently operated connections or where there might be a loading against the gate.2.7.4.3 The strength of a connector is determined by applying an outward force along its length (the major axis) using two round metal bars (see Figure 2.1). If the connector has an asymmetrical shape, the test load is normally applied along a line close to the spine. If the loading in use is not in such a position — for example, because of the use of wide tape slings or double ropes — the weaker, gated side of the connector will take more of the load and its failure load could be less than specified. Static strength tests resulted in strength losses of up to 45%. Therefore, care should be taken in use to see that asymmetrical connectors are loaded correctly, i.e. in a line close to the spine, or have a suitable factor of safety. See Figure 2.1.
