Sockets are the permanent half of the eme davit system — precision-machined bases in signature safety yellow, installed once at every lift point on your site. A single portable davit drops into each one with zero tools, engages on the proprietary Smooth Glide System, and rotates under load. Six standard variants plus a drop-in extender cover most install geometries; custom sockets are engineered to site for anything else.
Choose the socket by installation geometry. Use the same davit across the network.
Pick the socket by where you need the davit to sit and what it has to mount to. The Smooth Glide engagement is identical across every variant — your davit lifts the same way on a flush socket as it does on a 42-inch side-mount. Need more reach on a 1,100 lb lift? The Socket Extender drops into a Flush Mount, 8" Top Mount, or compact Side Mount and raises the pivot point.
Sits flush with the finished surface — concrete pad, deck plate, or vehicle floor. Ideal for high-traffic areas where a raised socket would be a trip hazard, vehicle pinch point, or visual obstruction.
A trapezoidal pedestal that rises 8 inches above the finished surface. Bolts to a horizontal surface where flush mounting isn't practical or where the socket needs visible identification as a rated lift point. The most common surface-mount install in the catalog.
Bolts horizontally to a wall, column, or structural beam — short cantilevered arm with a triangular gusset for stiffness. The standard side-mount for tight wall-clearance installs where a long reach isn't needed.
The 42-inch extended side-mount — a tall vertical post bolted to a wall surface, with the socket at the top of the post. Reaches over obstacles, around guards, or up to a higher working plane than the wall mount face alone can provide.
A 42-inch standalone vertical column topped with the socket. Lifts the davit pivot point above adjacent equipment, railing, or curb obstructions — common where a flush or 8" top-mount would put the davit boom too low.
Drops into a Flush Mount, 8" Top Mount, or compact Side Mount socket and raises the davit pivot point above the host installation. Use to clear a parapet wall, reach over an equipment guard, or temporarily increase the working height without re-engineering the permanent socket. Rated for the 1100 Series davit only — not for use with the 2200 Series or the 42" socket variants.
When the install location doesn't match a stock socket — odd-angle mounting face, non-standard offset, dock-edge mount, tank manway, integrated vehicle frame — eme engineers a custom socket to the site geometry. Engineer-stamped drawing supplied with every custom unit.
Every eme socket and davit pair uses the same proprietary low-friction interface — the Smooth Glide System. The davit pivots inside the socket on a precision-machined engagement surface that stays smooth under rated load and tolerates field debris (dust, light grit, water) without binding. No grease nipple, no service interval, no learning curve from one socket to the next.
Socket bore and davit stem are machined to a controlled tolerance — not just a slip-fit. The contact face carries the rotational load instead of relying on a bushing or bearing that wears.
The davit operator rotates the load from pickup to drop-off without setting the lift down. No swing crane, no re-rigging between angles — the Smooth Glide System is what makes this possible.
The engagement is intentionally not a lubricated bearing — there is no grease fitting and no bearing service interval. Routine inspection focuses on the socket structure, welds, protective cap, and engagement surfaces.
Every standard eme socket ships in the same bright safety-yellow powder coat — not as decoration, but as jobsite wayfinding. On a busy site, the yellow socket reads at a glance as a rated lift point. Crews don't have to remember where the davits drop in or which floor pad is structural; the yellow tells them.
Readable from across a plant floor, a rooftop, or a vehicle bay — no signage required to identify the lift point.
Yellow is industrial-safety convention for "caution / take note" — the same color used on hazard-marked equipment and PPE warning labels.
Powder coat — not paint — for jobsite resilience. Resists chipping under foot traffic, vehicle bumps, and chain-hoist contact.
Where the environment demands a different material spec — marine, wash-down, chemical exposure — we build the same socket geometry in 316 stainless steel. See the next section.
Some sites eat painted finishes alive — coastal air, salt spray, daily chemical wash-down, food-grade sanitation cycles, wastewater chemistry. For those, eme builds the same socket geometry in 316 stainless steel. Naturally corrosion-resistant, supplied unpainted, identical Smooth Glide engagement, available across every mount pattern in the catalog.
Salt spray, humid air, and coastal install conditions where powder coat eventually pits and lifts. Stainless holds the structural surface integrity that painted steel can't on a long-term outdoor install.
Food processing, dairy, beverage, and pharma facilities with daily high-pressure sanitation cycles. Stainless tolerates the cleaning agents and frequency that strip painted finishes within a year.
Treatment plants, chemical manufacturing, and industrial process facilities with persistent chemical exposure. Stainless can reduce the periodic strip-and-recoat maintenance cycle required by painted sockets in aggressive environments.
Marine-grade austenitic stainless — same family used on offshore equipment and food-contact fabrication.
Ships natural mill finish. Optional safety-yellow powder coat available if visibility is required for the lift point.
Same Smooth Glide engagement, same compatible davits, available in all five mount patterns including custom.
Manufactured per quote with engineer-stamped drawing and Certificate of Test at 125% of rated davit capacity.
A standard flush, top-mount, or side-mount won't always fit. Dock-edge mounts, tank manways, marine bulkheads, integrated vehicle frames, and angled mounting faces all need a socket designed to the geometry — not a stock part modified in the field. eme engineering builds the socket, supplies an engineer-stamped drawing, and load-tests the finished assembly before shipment.
Send dimensioned drawings, photos, or a sketch of the install location. Tell us the rated load, the davit series, and what the lift will look like.
eme engineering designs the socket to your geometry. Stamped drawing supplied for owner / structural review before fabrication begins.
Fabricated, welded under CSA W47.1 certification by qualified welders, finished in safety yellow (or 316 stainless), and load-tested at 125% of rated capacity before it ships.
Standard eme sockets are mild-steel construction welded under CSA W47.1 certification (the steel equivalent of the W47.2 aluminum certification used on eme's gantry and davit lines) by qualified welders — a Canadian Welding Bureau third-party credential for fusion welding. Davit + socket assemblies carry the same design factor on yield stress as the davit itself — well in excess of the proof-test load — with structures meeting CSA S157 (Canadian aluminum structural design), the same engineering framework the eme davit cranes are built to.
Custom-engineered sockets ship with an engineer-stamped drawing and a Certificate of Test at 125% of the rated davit capacity, so the pre-service proof test is already done and documented on arrival. Browse the full reference set for the technical details behind each spec.
