General

The swivels shown in this chapter illustrate just a small part of the swivels we have made or make. The swivels shown however ere the ones that are most asked so far. The standard range of swivels include:
•Ball swivels with alloy and DIN hooks,
•Ball swivels with round eyes,
•Swivels in all combinations of hooks, bows, round eyes and jaws.

Inspection, testing and maintenance

•Check the swivels daily visually for damages and dirt.
•Swivels should be inspected at least once a year by a surveyor for proper functioning and damages.
•Swivels should be taken apart at least every 4 years by a specialist, for inspection of wear, hidden damages or beginning cracks and have the swivels tested by an authorized testing body.
•After repair, swivels have to be tested by an authorized testing body.
•If swivels are supplied with grease nipples, preferably grease every 24 hours at continuous use and every fortnight at discontinuous use.
•Parts should be replaced if wear is 5% or more (e.g. hooks, jaws, bolts and eyes).

Directions for use

•For connections, only use components (sockets, shackles) that are suitable for the indicated working load limit (WLL).
•If the swivel is furnished with a trust bearing, then the swivel is designed to swivel under load. If the swivel is not furnished with a trust bearing, swiveling is allowed only without load.
•Alloy and DIN hooks are supplied with safety latch. Cargo hooks are not.
• Never side load, back load or tip load a hook.
•The hook must always support the load. The load must never be supported by the latch.
•Never use a hook whose throat opening has been increased or whose tip has been bent more than 10° out of the plane from the hook body or is in any other way distorted or bent. The latch will not work properly on a hook with a bent or worn tip.
•Never repair, alter rework or reshape a hook by welding, heating, burning or bending.
•When placing 2 sling legs in a hook, make sure that the angle between the legs does not exceed 90°.

•Never side load, back load or tip load a hook.
