20MM x 100MM Galvanised Long Link Chain - Caravan Secure Tether Galv

Product Information

Good slinging practice must ensure that the load is as safe and secure in the air as it was on the ground and that no harm is done to the load, lifting equipment, other property or persons. Protector chains are top of the tree according to Bennetts Insurance. Bennetts have done a lot of chain testing across many manufacturers and have created their own league table that shows how numerous products compare:

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%. 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.The new gun is expected to increase the rate of fire that is seen now on the Apache. The company is taking experience from its suite of advanced ammunition technologies, like the 30mm ammunition line, to develop 20mm projectiles “with significantly improved lethality against a range of targets including troops, [unmanned aerial vehicles], rotary- and fixed-wing assets, and other assets in the deep battlespace,” Canole said.

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. Quad bikes/ATVs are usually easier to secure than 2-wheel motorbikes but, again, you have to be careful that you really are looping the chain through something structural and not removable. E.g. the rear axle looks appealing but it's no good if the thief can slip off the chain simply by removing a wheel! Suspension wishbones etc are attached with a couple of bolts that can be easily removed. Most quads do have frames with structural members that are suitable but you have to look for them, and ideally loop the chain through several of them. Chinn, George M. (Lt.Col., USMC, Retd), ed.

Do not attempt lifting operations unless you understand the use of the equipment, the slinging procedures and the mode factors to be applied.Beware that the largest chains here are too big to fit many 'ordinary' ground anchors. The 19mm and smaller chains fit all our ground anchors, but the 25mm will only fit the Torc Mega anchor plus the Sub Major out of our range, for example. Note that the 25mm is not recommended with the Maxi as it is very tight fit and manufacturing tolerances mean it is unwise to expect it to fit.
