These eye bolts are designed with a shoulder at the point where the eye and the shank come together. This shoulder design reduces bending stresses on the shank and allows the eye bolt to be used for angular lifting if the shoulder is properly seated in the load.

Use a spreader bar with regular (non-shoulder) eye bolts to keep the lift angle at 90° to the horizontal. Use eye bolts at a horizontal angle greater than 45°. Sling strength at 45° is 71% of vertical sling capacity. Eye bolt strength at 45° horizontal angle drops down to 30% of vertical lifting capacity. Use a swivel hoist ring for angled

Van Beest offers a wide range of other lifting eye bolts, eye nuts and OL and EL eyebolts/nuts are valid for in-line lifting only up to an angle of 30°.

downguys at bolt hole 73) - See plate GY7SPL. Provisions for downguys are also provided on the steel crossarm and the 3-phase cutout and arrester bracket if required. E. GUY ANCHORS Two basic types of anchoring systems are used for downguys -- one is the screw type and the other is the "Manta-Ray" type.

Observe working load limitations (be especially careful with eyebolts used for angle lifts - see sling angle chart). 2. Visually inspect hoist ring prior to use. 3. Fully tighten hoist ring to recommended torque. Full thread engagement is required (no space between swivel bushing and lift). 4. Assure proper thread depth - do not shim. 5.

45° from bolt centerline. At an angle of 45°, rated capacity is reduced to 1/4 of the value in table. WN 580 | Lifting Eye Bolts. Steel • Inch Size.

Jul 26,  · G-277: SHOULDER NUT EYE BOLT. 2. SLING ANGLE. As the sling angle becomes smaller the tension being placed on the eye bolt increases while the eye bolts capacity diminishes drastically. It is very important that riggers understand this phenomenon completely in order to choose the proper eye bolt to make their lift safely.

Material: As specified by BS 4278 Hardened and Tempered S.W.L. Shown at 0° (vertical) angle of lift. Safety Note: Eyebolts under M12 are not recommended for lifting. Non-standard thread pitches available upon request. Various sizes from M6 to M80. Capacities (SWL - Safe working Load) from 100kg up to 30t. Self-coloured finish as standard.

The greater the angle, the less weight an eye bolt can hold. If the angle is less than 5 degrees, the weight capacity stays pretty much the same. However, at just 15 degrees, the weight capacity is reduced by 20%. For example, an eye bolt with a 1/4 inch shank can typically hold up to 600 pounds at a straight pull (no angle).

careful with eyebolts used for angle lifts—see sling angle chart below). of swiveling and pivoting hoist rings, rather than conventional eye bolts.

Fatigue rated at 1-1/2 times the Working Load Limit at 20,000 cycles. ! Working Load Limits shown are for in-line pull. For angle loading, see page 180. ! Meets
