Information

Load rings GN 587.1 for welding are designed for rapid mounting.

They provide high dynamic and static strength and can be load from any direction with approved safety (safety factor 4) for all loading directions.

The spring steel tape (Type F) holds the ring in any position and dampens any noise caused by vibrations. All parts are undetachably connected.

The two support lugs improve the bearing of hooks and enhance the support effect in the event of oblique suspension rings.

Load rings GN 587.1 comply with Mechanical Engineering Directive 2006 / 42 / EG.

This standard replaces the previous load rings GN 587.

Safety instructions

The above details refer to the maximum load in metric tonnes.

The configuration of the welding seam (HV) complies with the requirements of DIN 18800, i. e., the closed seam means that no corrosive deposits can settle; this also makes the load rings suitable for outside use.

Loading ring size	Size Welding seam	Length	Volume in cm³
b = 66 ( 1.5 t)	HV 5 + a 3	2 x 33	1.2
b = 77 ( 2.5 t)	HV 7 + a 3	2 x 40	2.6
b = 87 ( 4.0 t)	HV 8 + a 3	2 x 46	3.2
b = 115 ( 6.7 t)	HV 12 + a 4	2x 60	8.7
b = 129 ( 10.0 t)	HV 16 + a 4	2x 60	15.5

Welding must be made by an approved welder in accordance with EN 287-1.

The specified loading values are valid for an operating temperature of between –20 °C and +100 °C. Load capacities under higher temperatures provided on request.

If the load rings are used for lashing instead of lifting, the nominal load is doubled.

Operating instructions with more details and specifications are included with every delivery.
