The brand's hoist rings can pivot up to 360 degrees and safely lift loads up to 69300 lb. They feature adjustable brackets for attaching to machines or static loads.

Things To Consider

Cross-Reference Alternatives

RUD Chain's model numbers generally cross individual reference to the equivalent Crosby MPNs (manufacturer's part numbers). So, if you're looking for hoist rings & hooks that are either out of stock or obsolete, chances are Raptor Supplies has the alternate product available.

Shipping

These RUD Chain products are generally small in size and require compact packaging. They are suitable for courier shipment and not air freight.

Frequently Asked Questions

What are some safety instructions to follow while installing or operating the Rud excavator hooks?

  • Keep all body parts & objects away from the lifting process danger area.
  • Users should not exceed loads beyond the working load limit (WLL) of the hook.
  • The hooks should not have any technical modifications.
  • The load should be stable when lifting. Swinging & jerky lifting must be prevented.
  • All components and the hook should be checked for cracks & wear.
  • The lifting points, chain, hooks & hoisting rings should not contact aggressive acids, chemicals & vapours.

What are the effects of temperature on the working of Rud excavator hooks?

  • Rise in temperature causes a decrease in the working load limit of the excavator hooks due to the DIN / EN bolts used as lifting points.
  • At temperatures ranging from -40 to 100 degrees C (-40 to 212 degrees F), there is no reduction in the working load limit.
  • At temperatures ranging from 100 to 200 degrees C (212 to 392 degrees F), there is a 15% reduction in the working load limit.
  • At temperatures ranging from 200 to 250 degrees C (392 to 482 degrees F), there is a 20% reduction in the working load limit.
  • At temperatures ranging from 250 to 350 degrees C (482 to 662 degrees F), there is a 25% reduction in the working load limit.
  • Users must not operate these excavator hooks at temperatures above 350 degrees C (662 degrees F).

Why are some Rud hoist rings coloured pink?

Selected Rud lifting points like ring bolts, eyebolts, flanges & more are pink in colour to showcase the brand's basic testing & certification principles. Rud launched fluorescent pink powder coated products in its Grade 10 materials for use as an overheating indicator. The pink powder coating changes its colour in environments having temperatures above 200 degrees C. The colour changes from pink to ochre, then to brown and finally at the prohibited temperature near 400 degrees C, the colour changes to black with blister formation. Due to this colour change, the overheated lifting points like hoist rings can be easily identified & replaced before any accidents.
