GN 581 swivel lifting eye bolts offer a high load carrying capacity and are tested to meet high safety standards. The nominal values for load capacity in the table are for the most disadvantageous loading conditions, and are also clearly marked on the ring. Unlike DIN 580 lifting eye bolts, the GN 581 lifting ring bolt is captively mounted in the ring housing, yet rotates freely. The hexagon socket head bolt cannot be removed from the ring. The ring can be positioned in the direction of the load to make use of its optimum strength. The higher load bearing capacity as compared with DIN 580 lifting eye bolts permits the use of smaller mounting bolts.

Hex key cover plate allows assembly without the need to use tools: inserting the hex key in the hexagon socket of the bolt allows the bolt to be turned by hand. The hex key is removable. GN 581 lifting eye bolts comply with Mechanical Engineering Directive 98/37/CE and are BG tested. Other sizes available upon request.

The values given in parentheses refer to the load capacity of the corresponding DIN 580 lifting eye bolt. If such a value is not indicated the use of lifting eye bolts DIN 580 is not permitted. The bolt-on surface of the lifting eye bolt must be plane and at a right angle to the threaded borehole. The countersinking must be the nominal diameter of the thread. The shoulder of the socket screw must be in full contact with the

surface and the eye bolt must be able to rotate through 360. Before applying the load, turn the lifting eye bolt in the direction of the force. The lifting eye bolt is not suitable for frequent rotation cycles under load. In the case of assymetrical load distribution, each eye bolt must be capable of carrying the total load alone. In the case of load method G1, no cross load forces are exerted on the eye bolts.

Safety InstructionsThe load values given apply for the following data: Material: mild steel, tensile strength 37 kp/mm2 Mounting thread length: l2 d x d1 Load capacity for other materials and mounting length of thread on request. Operating instructions with more details and specications are included with order.
