5 Pinlok Sling Hook A versatile, general purpose hook suitable for most slinging applications with the added advantage of safety latch kits available for conversion to a Pinlock Safety Hook. 7.1/ Pinlok Grab Hook With reinforced saddle for firmer hookups and less wear, the Alloy 800 Pinlok Grab Hook features an almost round leg section to resist twisting or bending. Ideal for back-hooking. 7.1/ Pinlok Shortening Hook The Alloy 800 Pinlok Shortening Hook offers greater sling flexibility by allowing quick and effective shortening of the chain sling while being used at its full, unshortened, working load. Not to be used as bottom fitting or for back-hooking or reeving applications. 7.1/ IWR LIFTING

6 Latchlok Hook Able to be easily closed with one hand, the Alloy 800 Latchlok Hook will close itself when the load is engaged and will not disengage even if the load is temporarily set down. When the load is released, the latch is simply opened by pressing the release trigger, and stays open, making hook up very easy / Pinlok Latchlok Hook Designed for rugged, demanding and critical applications, the Alloy 800 Pinlok Latchlok Hook can be mechanically coupled to chain for easy assembly and use / Swivel Latchlok Hook With all the features of a Latchlok Hook, but with the added bonus of swivel action to assist in the removal of sling leg twist. Particularly suitable for high-rise lifting. N L M / D IWR LIFTING 6

7 Foundry Hook For use where large throat openings are necessary. Appropriate for foundry applications and unusually bulky attachment points Weld-on Hook The solution to lifting and spreader beam attachment problems, or for any fixed anchor points. Manufactured from treated alloy steel, the Alloy 800 Weld-on Hook allows for axial loading and positive locking of the safety latch WLL Weight (tonnes) N D L M appr.kgs Pinlok End Link A versatile link designed for use in single leg applications, reevable slings or as terminal end fittings. 7.1/ IWR LIFTING

12 Alloy 800 Maximum Working Load Limit (WLL) in tonnes Single leg slings 2, 3, or 4 slings Endless slings Chain Size Straight Adjustable Reeved Straight Sling Reeved Sling Basket Sling Reeved (mm) Sling Sling Sling 60º 90º 120º 60º 90º 120º 60º 90º 120º Sling The values expressed on this table exceed or meet the minimum requirements of AS and are stated in tonnes of 1000 kg Indicates that WLL applies to both rectangular and circular load. Indicates nip angle which must not exceed 120º. Indicates the sling angle is equal to twice the greatest angle of inclination of a leg to the vertical. * Use of a Grab Hook 16.0mm to 32.0mm reduces the WLL of straight slings to that of reeved slings. Use of a Pinlok Shortening Hook does not reduce the WLL. The above maximum working load limits are for general conditions of use to group classification of crane mechanisms of M3 as specified in AS WLL must never be exceeded, even at angles less than 60º or even if the load is flexible. For other than general conditions of use the WLL will be derated to confirm to the group classification of crane mechanisms as specified in AS Every care has been taken to ensure the accuracy of information contained in this document which supersedes earlier publications, however PWB Anchor Ltd shall not be liable for any loss or damage howsoever caused arising from the application of such information.

13 Care, Use and Inspection of Alloy 800 Chain Slings Care Store Alloy 800 chain slings on A-frames or wall racks in a clean dry place Lightly oil Alloy 800 chain slings before prolonged storage. Never heat-treat Alloy 800 chain slings. Use Always inspect a chain sling before use to ensure it is free from damage or wear. Ensure that the load is evenly distributed on all sling legs. Ensure that the chain is free of twists and is protected from any sharp corners on the load. Commence the lift slowly, taking up the slack gradually. When lowering, avoid the possibility of crushing the chain by ensuring that the load does not land on it. Inspection It is important to inspect chain slings regularly and that a record is kept for each chain sling. Chain sling inspection record cards are available. If necessary, clean the sling before inspection. Every chain link should be individually inspected for signs of wear, twisting, stretching, nicks, or gouging, and any worn link measured to determine degree of wear. Oblong links and hooks should be inspected at their loadbearing points for signs of wear or distortion, eg widening of hook throat opening. Defective chain links or fittings should be clearly marked to indicate rejection, and the chain sling withdrawn from service until repaired. Connecting Links should be inspected for any signs of wear at their loadbearing points, for excessive play of the load pin within the body halves and for impaired rotation of the body halves around the load pin. Enter all results in the sling inspection record card. Effects of Hazardous Conditions Heat Conditions The strength of all chain slings is adversely affected by heat so care must be exercised when using at elevated temperatures. Where temperatures are likely to be higher than 200ºC reductions in the working load limits of Alloy 800 slings should be applied. (See table) Heat Treatment Alloy 800 Chain & Fittings do not require periodic heat treatment and must never be heat treated. Corrosive Conditions Alloy 800 Chain & Fittings should not be used in acid or other corrosive environments. Galvanising Temperature Range ºC Reduction of WLL while heated Up to 200 Nil % % Over 400 Do not use Alloy 800 Chain & Fittings must never be hot dipped, mechanically galvanised or electroplated except by PWB Anchor. Hot dipped galvanised slings must always have their working load reduced by 20%. 13 IWR LIFTING
