3M DBI-SALA Davit 8518386 Adjustable Davit Mast & Arm

The 3M DBI-SALA Davit 8518386 is the adjustable version of the DBI-SALA davit system. Its arm adjusts for both offset reach and height and rotates a full 360°, so a single mast can serve manholes and vessel openings of different sizes across a plant. The steel mast is rated for 158 kg (350 lb) lifting and 4.5 kN (1,000 lb) fall arrest.

Overview

With fixed davit arms such as the 8518382, a plant with many differently sized openings has to stock several arms with different offset reaches — costly to buy and complex to manage. The adjustable 8518386 lets one mast cover multiple configurations, simplifying inventory and speeding up setup at each access point.

Key features and benefits

• Adjustable offset reach and height: one mast fits a range of opening sizes and positions.
• 360° rotation: lift the load, swing it clear of the opening and lower it safely.
• Dual rated: 158 kg (350 lb) lifting capacity and 4.5 kN (1,000 lb) fall-arrest rating.
• Premium steel construction: strong and corrosion-resistant for long service.
• Modular system: works with DBI-SALA bases, winches, hoists and rescue self-retracting lifelines.

Main industries and applications

• Confined-space entry & rescue: tanks, silos, vessels and manholes of varying sizes.
• Water & wastewater treatment: chambers, wet wells and digesters.
• Oil & gas / petrochemical: storage tanks and process vessels.
• Power generation: boilers, hoppers and access shafts.
• Manufacturing: sites with multiple, differently sized confined-space access points.

Frequently asked questions

What is the 3M DBI-SALA Davit 8518386?

It is an adjustable davit mast and arm used in confined-space lifting and rescue systems. Its reach and height adjust and it rotates 360°, so one mast can serve several different openings.

How is it different from the fixed Davit Arm 8518382?

The 8518382 has a fixed reach, while the 8518386 adjusts for offset reach and height and rotates 360°. One adjustable mast can therefore replace several fixed arms across a site.

What is it rated for?

The Davit 8518386 is rated for 158 kg (350 lb) of lifting and 4.5 kN (1,000 lb) of fall arrest.

Does it need a base?

Yes. The mast fits into a permanently installed davit base, which is selected to suit the mounting surface and sold separately.

What can be attached to it?

It supports DBI-SALA winches, hoists and rescue self-retracting lifelines, so you can build a complete confined-space lifting and rescue setup.
