Safe Working Loads

Each size range of Gripple hangers has a specification which must be adhered to in order to ensure safe operation. When suspending vertically, the maximum load rating for each size range is shown in the table below.

Size
Safe Working Load (SWL)
No.110 kg
No.245 kg
No.390 kg
No.4225 kg
No.5325 kg

Hanging at Angles

The load rating for a Gripple Hanger is based on the suspension being hung vertically. If the wire rope is at an angle, an additional sideways force is applied which increases the load on the suspension. The net effect is shown in the table below.

Wire Rope Construction & Cross Sections

The wire ropes used within our product ranges are manufactured with a galvanised coating in accordance with the norm EN 12385.
