Extra Improved Plow Steel, a higher grade of wire rope. Most general engineering ropes have a tensile strength of 180Kgf/mm2 where as EIPS ropes have a tensile strength of 210Kgf/mm2 or more

Collared Eyebolts should be used in conjunction with suitably sized shackles and may be used up to the marked safe working load (SWL) for axial lifting only. Collar eyebolts may be used for non-axial loading provided that the SWL is reduced by the appropriate factor (see tables 7 and 9; BS4278:1984.). In non-axial loading the load should be applied within ± 5° of the plane of the eye.
Dynamo Eyebolts are intended for axial lifting only.
Eyebolts with link which can be hooked into directly, offer considerable advantages over collared eyebolts when loading need to be applied at angles to the axis and/or the plane of the eye. Their SWL's are relatively greater than those of collared eyebolts used in the same condition and, unlike the collar eyebolt, the load can be applied at any angle to the plane of the eye. Eyebolts with link may be loaded in any direction up to the marked SWL, provided that the angle of the load to the axis of the screw thread of the eyebolt does not exceed 15°. Eyebolts with link may be used for non-axial loading at inclinations greater than 15° provided the SWL is appropriately reduced (see table 8; BS4278:1984.)
