Soil Bearing Capacity For the purpose of this code, undisturbed soils have been determined to have a soil bearing capacity of 1,000 PSF. A stand with a soil bearing capacity of 1,000 PSF may be improved by: o Adding 6 inch of 3/4 inch minus crushed rock compacted with two passes of a vibrating machine increases soil bearing capacity to 1,500 PSF.
Best Practices When Using Lifting Eye Bolts | G.L. Huyett
2021. 6. 24. · Practices to avoid when using lifting eye bolts: Running a Sling Through Eye Bolts. It's often convenient to run a sling through a pair of eye bolts, however, it should be avoided. Attaching a sling in this manner applies angular force to the eye bolts and, as we mentioned earlier, angular forces drastically reduce a lifting eye bolt's WLL.
Regular Nut Eye Bolt Shoulder Nut Eye Bolt Machinery Eye Bolt G-291 G-277 G-279 Important Safety Information— Read and Follow Inspection/Maintenance Safety: † Always inspect eye bolt before use. † Never use eye bolt that shows signs of wear or damage. † Never use eye bolt if eye or shank is bent or elongated.
How Much Weight Can An Eye Bolt Hold? [ANSWERED] - Lift-All Company
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). However, at a 15 degree angle, the maximum weight capacity drops to 480 pounds (80% of the "straight pull" weight capacity).
304 stainless steel eye nuts are more corrosion resistant than galvanized steel. 316 stainless steel are the most corrosion resistant eye nuts. Note: Capacity applies to the eye nut only. The stud or bolt you use will affect the overall capacity. Eye nuts are for vertical lifting only. Warning: Never use to lift people or items over people.

DIN 580 Specification specifies the properties of steel and stainless steel eyebolts and provides information on their correct use in lifting operations (as part of slings and as load handling equipment). Eye bolts according to this standard can be used in a temperature range from −20 ° C to +200 ° C without any restriction of the load capacity.
The RC of an eye bolt is determined from a straight, zero degree, lift. As DIAGRAM 2refers, a significant reduction in capacity is experienced any time a lift changes from zero degrees. Although the ANSI design specification denotes a working load capability for a 90° lift, we do not recommend using a lifting angle beyond 45°.
Eye Bolts 101: How to Safely Select and Use the Right Eye Bolt For You
Angular lifting using plain pattern eye bolts is not recommended. • The marking on the eye bolts represent the thread size, not necessarily their rated capacities. • Always check the manufacturer's specification for rated capacity before conducting any lift. • Angular lifts greater than 45° from the shank centreline is not recommended.
