eye bolt lifting capacity chart

Crosby® 405 Lifting Eyes Crosby® 405 Lifting Eyes > Pad Eyes. Avoid rotating movement during transport. Pentagonal shape – significantly different from the DIN 580 eyebolt. (sold separately) • Multiple bolt lengths available to meet specific application requirements. Avoidtwisting movements during transport.■ The given WLL is only valid in connection with threaded bolts of at least quality class 10.9. Grade-8 Eye Bolts offer up to 4 times higher lifting capacity in certain applications. A tolerance of ±5º is acceptable but it is a matter of luck whether this will be achieved when first screwed in because the eyebolt manufacturer has no control over the start point of the threaded hole. This design is called a collar eyebolt and can be considered as the general-purpose eyebolt.The underside of a collar eyebolt has a thread run-out at the top of the screw thread and an undercut of the collar. 4.If the plane of the machinery eye bolt is not aligned with the sling line, estimate the amount of unthreading rota - MENU. They should therefore be subject to a thorough examination by a competent person at least every six months. • Never insert a hook in an eye bolt, always use a shackle. However, BS 4278 does offer a third option and that is the eyebolt with link. Meets or exceeds all the requirements of ASME B30.26 (US) 360° swivel and 180° pivot action. It allows manufacturers to design eyebolts capable of working to the same angle factors as used for slings. deepri.com ... (Stone Bolt) DIN 529 B - Anchor … Machinery Lifting Eye Bolts in this catalog, and other catalogs to which you may refer, could show a higher Working Load Limit (WLL), or Rated Capacity (RC). Boltport is a manufacturer of Lifting Eye Nuts in metric and imperial sizes with coarse, fine, extra fine, and custom threads to various dimensional standards and material specifications. shoulder pattern eye bolts. If the VRS permanently to remain at the point of force introduction, it must be tightened with a torque of 5 Nm. This is done using shims from the manufacturer. These have bearings which allow for 360º rotation which removes any alignment problems and the link will tilt to the line of force. For a given thread size the axial working load is less than that of a collar eyebolt but the reduction. By also reducing the size of the eye, it keeps the leverage to a minimum. Dale Lifting and Handling Specialists New eyebolts are required to fit old equipment which may have imperial threads.

Their rating and the alignment requirements are still those of a collar eyebolt. • Bolt is secured with E-clip, threads are grooved. Sizes of VRM - see drawing VRS-StarPoint. Use a swivel hoist ring for angled lifts. Manchester M11 2QA. For angular loadings see RUD VRM, Eyenuts - metric coarse ( BSW thread available)• Material: high tensile steel• Safety Factor: MBL equals 5 x SWL• Finish: self colour, electro-galvanised upon request• Certificates: this product is supplied with a works certificate as standard, Eye nuts are available in (Click on type required to view more), Eyenuts - metric coarse thread - Self Colour, Eyenuts - metric coarse thread - Zinc Plated, For Axial loads only (NOT TO BE USED FOR ANGLED LIFTS), Bownuts - metric coarse ( BSW thread available)• Material: high tensile steel• Safety Factor: MBL equals 5 x SWL• Standard: generally to B.S. Standard forged eye bolts should not be used with angular lifts. These new generation lifting points offer advanced engineering and increased load capacities over standard eyebolts. The given WLL for 90° is only valid in connection with threaded bolts of at least quality class 10.9. Safety factor 4: 1. For the BS 4278 collar eyebolt, the reduction factors are: 0.63 for angles up to 15º to the vertical; 0.4 for angles up to 30º; 0.25 for angles up to 45º. When used at an angle, the working load of a collar eyebolt must be reduced to take account of the different stresses imposed. Parkhouse Street Industrial Estate We are engaged in offering a wide range of Eye Bolt, which can be availed in various shapes and sizes t. Standard : ASTM / ASME SB 160 / 164 / 425 / 166 / 446 / 574 / 472 The eyebolt has a threaded shank or rod which is securely screwed into a structure. The nut thread must be engaged to 100 % with the bolt thread. Load ring foldable, Marked with full 100% WLL in any load direction. Assemblies of material thickness of approximately 8 *M (for M8 - M30) and 5 *M for (M36 - M48) can be realised respectively. Forged From High Tensile Alloy Steel Some have a latch to lock the bolt to the link thereby allowing the link to be used as a lever to tighten or slacken the bolt when fitting. Use swivel hoist rings for rigging. Lifting Eye Bolts have a safety factor of five times the WLL/RC with proper seating and full thread engagement. Sometimes the hole they are screwed into is there specifically for the eyebolt. • Never repair or reshape an eye bolt or eye nut by welding, heating or bending as this may affect the Working Load Limit; • Never machine, grind, or cut an eyebolt. to 13.000 kg. Dynamo Eyebolts - For Axial loads only (NOT TO BE USED FOR ANGLED LIFTS). The eye bolt must be aligned during installation and tightened to secure it against rotation during lifting. These are the eye nut and bow nut. Description: GN 581.5 swivel lifting eye bolts offer a high load carrying capacity and are tested to meet high safety standards. Unmarked eyebolts should be immediately removed from use. • Zinc Plated (Yellow Chromate) finish for increased corrosion protection, CROSBY HR125M are available in (Click on type required to view more), CROSBY HR125M - SWIVEL HOIST RING - METRIC, CROSBY SS125M - STAINLESS STEEL SWIVEL HOIST RINGS - METRIC, • Wide range of capacities available: Also available with UNC thread. As such most countries require that they are periodically inspected or thoroughly examined. RUD RM Eye nuts are available in (Click on type required to view more). Although Dynamo eyebolts are a relatively low-cost item, the limitation on axial loading is obviously a considerable disadvantage as, for many applications, two or more lifting points are required.The answer is an eyebolt with a large collar between the eye and the screw thread. • Always be sure threads on shank and receiving holes are clean. Also, the eyebolt manufacturer has no control over the tolerances of the screwed hole, hence the restriction to coarse series threads. Prior to the introduction of a British Standard, dynamo eyebolts were manufactured to a wide range of ‘commercial’ patterns of varying quality. • Rated at 100% of Working Load Limit for angles up to 90 degrees. DIN 580 (Foreign) standard eye bolts made of steel and of stainless steel. Get A Quote . G-100 Lifting Point are 360° rotation with 90° pivot function. The max. Thickness of spacers must exceed this distance between the bottom of the load and the last thread of the eye bolt. GRADUP lifting rings offer improved WLL. • Read, understand, and follow information in diagrams and charts relevant to eyebolt types before use. It is accepted practice to wrap threads in insulating tape or similar. A gold star goes to one tackle store keeper who carefully wrapped the threads, strung them in sets hung on a board which was clearly marked with thread type, WLL and the inspection period colour code information. As this standard is very new and not yet implemented into national standards, it remains to be seen how many manufacturers will take advantage of it. Standard eyebolts can have other screw threads and BS 4278 does allow for imperial threads for replacement purposes. with a consequence of deformation and alteration of the material structure. Although a collar eyebolt is designed for angular use it is nevertheless necessary to align the eye to the line of pull. VRS High Capacity Eye bolts can be adjusted to the direction of pull. If an angular lift is required, a properly seated shoulder pattern machinery eye bolt must be used..
