Manufacturing Proof Force (MPF) is the force to which during manufacture the chain is subjected to. The mean stress at this load is 500n/mm2 (MPA) which is 2.5 times the working load limit.

Chain slings are available in a range of material grades, sizes and assemblies. Select the slings to be used and plan the lift taking the following into account: This document is issued in accordance with the requirements of Section 6 of the Health and Safety at Work etc Act 1974, amended March 1988. It outlines the care and safe use of general purpose CHAIN SLINGS and is based on Section 13 of the LEEA Code of Practice for the Safe Use of Lifting Equipment.* It should be read in conjunction with the requirements for general purpose slinging practice, given overleaf, which form an integral part of these instructions. This information is of a general nature only covering the main points for the safe use of chain slings. It may be necessary to supplement this information for specific applications. When using chain slings always:

Single Leg, 2 Leg, 3 Leg and 4 Leg Lifting Slings are available with various fittings... Clevis Sling Hook Once the first production article is built, the company will transition into full-scale live firing in the late spring or early summer, Canole said, and will hand it over to the government to go into additional testing.

Establish the weight of the load, ensure the lifting method is suitable and inspect the sling and attachments for obvious defects. Prepare the landing area making sure the floor is strong enough to take the load. Follow any specific instructions from the supplier.Multi-leg slings exert a gripping force on the load which increases as the angle between the legs increases and this must be taken into account. We offer chain cutting services, where multiple lengths of chains are required, saving you time, equipment hassle and manpower. Galvanised chain is still long lasting (although not as long as stainless), but a cheaper alternative to Stainless. Minimum Breaking Load (MBL) is the minimum force of which the chain must withstand before failure. The mean stress at this load is 800n/mm2 (MPA). The minimum elongation before failure is 20%. Slings are available in single, two, three and four leg or endless form. In practice it will be found that chain, wire rope and fibre rope slings are available in any of these configurations but that flat woven webbing is limited to single leg and endless whilst roundslings are only supplied in endless form. The maximum load that a sling may lift in use will be governed by the slinging arrangement (mode of use) and may vary from the marked SWL.** In the case of textile slings the SWL for the various modes of use is usually given on the information label. In other cases it is necessary to multiply the marked SWL by a mode factor.***

The area should be kept clear. Minimum Breaking Load (M.B.L.) is the minimum force which chain or components must withstand before failure. The mean stress at this load is 800n/mm2 (MPA). The minimum elongation before failure is 20%. The Protector 16mm chain has the following link dimensions (nominal): 132 x 62mm outside; 100 x 30mm inside, throughout its length (an elongated end link is not required). It is constructed from 16mm diameter bar. The smallest rectangular hole it will fit through is about 62 x 34mm, but that would also be a tight fit. It is again fitted with a protective fabric sleeve, usually a bronze colour (adding about 4mm maximum to the width noted above). Also available as a Noose Chain - see below. Stainless A4 AISI 316 marine grade is ideal for corrosive environments or just for very long life outdoors.

Video: Help on choosing the right chain: Protector Range Overview The following information is based on Section 1 - Appendix 1.5 of the LEEA Code of Practice for the Safe Use of Lifting Equipment.* It should be read in conjunction with the instructions for the safe use, given overleaf, of which it forms an integral part and with any specific instructions issued by the supplier. This information is of a general nature only covering the main points for the safe use of various types of slings for general lifting purposes. ALWAYS: Chain lengths overall are also nominal and subject to manufacturing tolerance as well as being potentially up to a link over- or under-length, relative to the descriptive length assigned. This is because a whole number of links will invariably not be an exact number of metres or half-metres overall, for example.The Protector 13mm chain has the following link dimensions (nominal): 106 x 48mm outside; 80 x 22mm inside. It is constructed from 13mm diameter bar and has a fabric sleeve that is usually bronze in colour (adding about 4mm maximum to the width noted above). If you've got a round hole 52mm diameter, the 13mm chain should slide through OK. It will also fit through a rectangular hole, e.g. 52mm x 35mm, but that requires the links to settle against each other, and more closely as the slot gets narrower, down to the absolute minimum of around 52mm x 30mm high (where it would be quite fiddley to get it to go through). Also available as a Noose Chain - see below. Note: The chain fittings show above are the more popular hooks and leg length adjusters types. Chain sling assemblies can be supplied with alternative fittings in Grade 8, Grade 10 or Grade 12 to suit your requirements...
