LINQ davit arm cantilever, stainless steel

The LINQ Davit Arm is a cantilever arm built to give you a safe and secure overhead anchor point when you are working into a confined space. It is the part of a davit system that reaches out over the opening, so a person can be lowered in, raised out, or held on a fall arrest line while they work below.

It is made from durable stainless steel, which is a sensible choice for the damp, dirty conditions you often find around tanks, pits, shafts and other confined entries. The arm swivels a full 360 degrees on its mounted base, so once a worker is on the line you can rotate them clear of the opening rather than dragging them sideways.

The detail that sets this arm apart is the three adjustment points built into the cantilever. They let you change the reach and the position of the anchor, which matters when the roof or the area around the entry is tight and you cannot stand the system wherever you would like. If you want to confirm the listed details before you commit, you can view the LINQ Davit Arm on Done Right Safety.

Choosing the right arm for your entry

Start with the entry itself. Measure how far the anchor needs to sit over the opening and how much room you actually have above and around it. The three adjustment points on this arm exist for exactly this reason: they let you dial in the reach so the line hangs where you want it, even when the roof is low or the area is cramped. Think about how the arm pairs with a base too, since the arm and the base together make the working system.

Setting it up and checking it

The arm fixes to its mounted base, then swivels a full 360 degrees once it is in place. Before anyone goes on the line, set the adjustment points for the reach you need and confirm the arm rotates freely and locks where you expect. Run through the swivel with the entrant clear of the hole, so you know you can rotate them off the opening on the way out. Always follow your own confined space procedure and a competent person's sign off, and pair the arm with a winch, fall arrest or rescue device that suits the task.

Inspection and care

Stainless steel handles wet and corrosive conditions well, but the arm still needs regular inspection like any height safety equipment. Look over the arm, the adjustment points and the swivel for wear, cracks, distortion or seized movement before each use. Keep it clean and dry between jobs, and have it checked at the intervals your site and the manufacturer require. If a part is damaged or you are unsure it is fit for service, take it out of use and confirm the details on the product page or datasheet.

These are like-for-like same type height safety options from the confined space range, so the comparison below is a genuine apples-to-apples look rather than adjacent alternatives. The LINQ Davit Arm is the overhead arm, the LINQ Davit Base is the floor mount it sits on, and the LINQ Confined Space Rescue Kit 1 is a packaged winch based rescue system, which helps show where the arm sits in a full setup.

If you already have a base and need the arm, or you are building a setup for an entry with limited roof clearance, the Davit Arm is the piece you want, since its three adjustment points are what give you the reach. The Davit Base is the floor mount the arm sits on, so reach for it when you are installing or replacing the mounting point itself, and note it lists EN375:2012 and AS/NZS 5532:2013 on its page.

The Confined Space Rescue Kit 1 answers a different need. It is a complete winch based rescue package with 25m of wire rope that one person can set up and carry, and it lists AS/NZS 1891, AS 2865 and EN1496:2006. Pick it when you want a ready to go rescue solution rather than the individual davit components.

For a confined space crew, this arm covers the basics that matter. Stainless steel construction suits the wet and corrosive spots where confined entries usually live, the 360 degree swivel lets you rotate a worker clear of the opening, and the three adjustment points give you the reach to work around an awkward roof. Those points are what make a davit arm genuinely useful on a tight site, and they are all confirmed on the listing.

What the listing does not state is the technical detail you would normally want pinned down before purchase: there are no standards, load ratings or measurements shown here. That is not a knock on the product, it just means those points need confirming rather than assuming. The closely related LINQ Davit Base, for example, does list EN375:2012 and AS/NZS 5532:2013 on its page, so it is worth checking what this arm and your chosen base reference together.

Bottom line: a sensible stainless steel cantilever arm for confined space work where reach and corrosion resistance count. Treat the standards, ratings and any capacity figures as items to verify on the product page or datasheet, and make sure the arm is matched to a suitable base and to your rescue or fall arrest plan.
