Welded in Canada.
Engineered to Code.
Tested Past Spec.
Every aluminum gantry, davit, and beam that ships from the eme facility goes through the same five-step build: engineered to ASME and CSA standards, welded under CSA W47.2 certification by qualified aluminum welders, assembled with Grade L9 fasteners, load-tested to 125% of rated capacity with a calibrated load cell, and documented with an engineer-stamped drawing and Certificate of Test before it leaves the floor.

One Documented Process. Every Crane That Ships.
Whether the order is a single 1100 davit or a fleet of 22000 gantries, the build path is identical. The repeatability is the point — a lift-plan reviewer should be able to predict what's in the documentation pack before they open it.
- 01
Engineering
Every configuration starts at a structural engineer's desk. Gantry crane designs are sized to ASME B30.17 and applicable CSA requirements; Eagle Beam lifting beams are designed to ASME BTH-1. Every design carries explicit capacity ratings, and the engineer-stamped drawing that comes out ships with the finished unit.
- 02
Cut & Weld
6061-T6 aluminum extrusion cut to length, prepared, and fusion-welded under CSA W47.2 certification by qualified aluminum welders — the Canadian Welding Bureau's third-party audited program for aluminum fusion welding. Weld procedures follow AWS D1.2 (Structural Welding Code — Aluminum), with CSA W59.2 the Canadian procedure-code equivalent. Documented procedure qualification records (PQRs) and welder qualifications (WPQRs) on file.
- 03
Hardware & Assembly
Welded structure paired with Grade L9 chromate-plated fasteners, caster assemblies, height-adjustment pins, and trolley hardware. Every fastener spec'd against the engineering drawing — no field substitutions, no surprise hardware grades.
- 04
Load Test
OSHA 1910.179(k)(2) caps the rated-load proof test at 125% of rated capacity unless the manufacturer recommends otherwise — eme's manufacturer-recommended per-unit production test is the 125% level itself. eme runs that 125% proof-load test on every unit with a calibrated load cell that reads the actual force on the structure, not a calculation, and records the result on the Certificate of Test that ships with the unit. Separately, almost all eme gantry and davit designs are additionally qualified by a 150% proof-load test on the P.Eng-stamped drawing — so the per-unit test verifies margin already validated at the design level.
- 05
Document & Ship
Engineer-stamped drawing, Certificate of Test, operator manual, and assembly instructions ship in the documentation pack with every unit. That's the documentation a lift-plan reviewer, structural engineer, or facility safety officer needs to sign off on the equipment before it lifts.
The Spec Sheet Behind the Spec Sheet.
The structural materials, welding certification, and hardware grades used across the eme product line. Every claim on a product page traces back to one of these decisions.
Six Codes That Cover Every eme Build.
Gantries: ASME B30.17 · OSHA 1910.179 · CSA S157 · CSA W47.2 welding.
Davits: design factor on yield stress well in excess of the proof-test load · CSA S157 · CSA W47.2 welding.
Eagle Beam: ASME BTH-1 · ASME B30.20 · CSA S157 · all-bolted construction; CSA W47.2 not applicable to the Eagle Beam load path.
