Description
Screw connectors (screw carabiner, chain connector) are mainly used to absorb tensile forces when crossing ropes, wire ropes or Chains on fixed components. They are also regularly used as emergency links 8Rapid links) for connecting chain links. The Use of a screw connector allows the easier replacement of a damaged stainless steel chain. or a wire rope. The curved shape makes the connection more movable. Screw connectors are often A useful alternative to carabiner hooks, snap hooks and shackles. In the past, their use has proven itself in the following areas: Water sports, boat building, boating, shipping, yacht construction, gardening and landscaping, food and Beverage industry, water and wastewater technology, machine and plant construction, conveyor technology, Play equipment on playgrounds, attachment of sun sails and awnings. These screw connectors are not suitable for lifting purposes as part of lifting equipment or load handling equipment. developed and manufactured. Therefore it is used as a hoist, stop means or load handling means, especially in the area of application of the machine guidelines 2006/42/EC, not permitted. For calculating the workload, have been in the past. a safety factor of 3 for occasional use. For permanent and dynamic load has been calculated with a safety factor of 4. Assuming the screw connector is regularly or dynamically loaded and has a Breaking load of 2000 kg. Then the working load is calculated as follows: Working load = breaking load/safety factor. Working load = 2,000 kg / 4. Working load: 500 kg.
