INTRODUCTION INTRODUCTION

General

In case you do not use the products yourself but are reselling these as part of a manufactured product,
please take our general cautions and warnings into account and make these known to your customers as
well. In any case, we do not accept any responsibility or liability, nor can we be held responsible for any
misuse or damage with, by or at your customers due to negligent use.

Definitions

Material
Various raw materials are used for the production of shackles, hooks and other lifting devices, depending on
the use of the finished product. The following raw materials may be used:
• Mild steel, untreated, grade 3;
• High tensile steel, untreated, or normalized, grade 4;
• High tensile steel, quenched and tempered, grade 6;
• Alloy steel, quenched and tempered, grade 8;
• Alloy steel, quenched and tempered, grade 10;
• Stainless steel AISI316L or AISI316, grade 5.

Load
Following terms are used to define a load:
• Working Load Limit or WLL: the maximum load the product is designed to support, in general use
and in in-line lifting.
• Proof Load or PL: this is the load applied on proof testing the product. At this load the product may
not show visual deformation. For information about the proof load applied, we refer to the separate
paragraph on testing.
• Minimum Breaking Load or MBL: the minimum load at which the product may fail or no longer support
the load. Where applicable the MBL is specified.
• Shock Load: a sudden impact of the load on the lifting product. Shock loads are to be avoided at all times
since they increase the stress on the product significantly and may affect its product life.

The unit that is used in this catalogue to indicate WLL, PL and MBL is t, which stands for metric ton.
Safety factor
®
This indicates the ratio between the MBL and the WLL. For the standard range of Green Pin shackles, for
example, the safety factor is 6:1. This means that the shackle may only break once it is overloaded by a factor
of at least 6 times its designed WLL. Green Pin chain fittings have a safety factor of 4:1.

Product dimensions
All product dimensions mentioned in this catalogue are nominal dimensions. Product design, materials
and/or specifications may be changed without prior notification.
Finish
Products can have the following finish:
• Self coloured: the product is delivered in the condition as it has been forged or machined and has
undergone no specific finish treatment.
• Electro-galvanized: the finished product is electro-galvanized according to the customary standards.
The thickness of the galvanization is at least 5 μm.
• Hot dipped galvanized: the finished product is hot dipped galvanized according to the customary
standards. The thickness of the coating is at least 70 μm.
• Painted: the finished product is painted in a specific colour.
• Polished: stainless steel products are polished.
Standard
These refer to the specific standards indicated for the product.
Temperature range
This indicates the temperature range at which the product can be used. Beyond the advised temperature
range the WLL of a product may be affected.
