Lowering the load
The point of destination of the load should be prepared and should be adapted to the weight and shape of
the load. The access to this site must be clear of any unnecessary obstacles and people. The load should
be lowered carefully. Avoid trapping the sling beneath the load as this may cause damage to the load or
sling. Before taking the tension off the sling legs, the load should be checked to ensure that it is properly
supported and stable. The sling should be removed by hand and not with the lifting device. The load should INTRODUCTION
not be rolled off the sling as this may damage the sling.

Storage of slings
When not in use slings should be kept on a properly designed rack. They should not be left lying on the
ground where they may be damaged. If the slings are left suspended from a crane hook, the sling hooks
should be engaged in an upper link to reduce the risk of sling legs swinging freely or snagging. If the slings
are out of use for some time they should be cleaned, dried and protected from corrosion, e.g. lightly oiled.
Maintenance
Slings must be regularly inspected in accordance with the safety standards valid in the country of use.
A competent engineer should examine the sling, observing the following:
• the sling markings (ID, WLL) must be legible;
• there may be no distortion of the upper or lower end fittings;
• sling leg stretch and wear may not exceed the tolerances.
If the identification tag of the sling is missing and the necessary information is not marked on the sling itself,
®
the sling should be withdrawn from service. Use original Green Pin spare kits to replace parts (such as a
load pin or the latch of a hook) or if a load pin is misused, damaged or distorted.
Limitations in use
• Never modify components by welding, heat treating, grinding or any other process. It could alter their
mechanical and/or chemical characteristics;
®
®
• Consult Green Pin if the sling is to be exposed to highly concentrated chemicals. Green Pin products
may not be used under chemical influences such as acids or alkaline solutions;
• The rating of lifting accessories in European Standards assumes the absence of exceptionally hazardous
conditions. This concerns offshore activities, lifting of persons and lifting of potentially dangerous loads.
In such cases the degree of hazard should be assessed by a competent engineer and the WLL adjusted
accordingly;
• If a product is used under extreme temperature conditions, the WLL must be reduced. We refer to
the relevant product chapter in this catalogue for guidance on use at extreme temperatures.
