Eagle Beam
Eagle Beam · all-aluminum, all-bolted lifting beam
Engineered, Welded, and Tested for North American Jobsites
Engineered to
  • ASME BTH-1 Category B Design of Below-the-Hook Lifting Devices
  • ASME B30.20 Below-the-Hook Lifting Devices — safety
  • Aluminum Design Manual (ADM) US aluminum structural design
  • CSA S157 Strength Design in Aluminum
Construction
All-Bolted Construction
No welded joints in the load-bearing structure — so welding certification does not apply. The HAZ failure mode in welded aluminum is eliminated by design.

Steel comparison based on published / catalog steel lifting-beam weights for equivalent rated capacity and spread. Exact steel beam weight varies by manufacturer, service class, and configuration.

Technical Spec Matrix

Capacity & weight by spread.

Estimated beam weight (lb) at each spread position, by capacity. Adjustable spread positions: 3 per side on beams 6 ft and greater, 4 per side on beams over 20 ft. Custom spreads and lengths available on request.

What Makes It Different

Four design choices that set Eagle Beam apart.

eme makes one below-the-hook lifting device — and it's built for the parts of the job that don't tolerate guesswork. Every feature below was chosen to remove a category of risk from your lift.

Construction

All-bolted. Zero welds in the load path.

Every load-bearing joint on Eagle Beam uses a Grade L9 fastener, not a weld. No heat-affected zones, no weld-quality risk to certify, no consumable-related variation between units. The beam ships exactly as designed — the bolts are the design.

About Grade L9 fasteners→
Weight

Up to 87% lighter than steel.

At equivalent capacity, an Eagle Beam weighs a fraction of its steel counterpart. The lightest configuration is 37 lb — one-sixth the weight of the equivalent steel beam. Crews carry, position, and adjust by hand; no second crane to move the lifting beam.

Aluminum vs. steel guide→
Standard

ASME BTH-1 Category B. 3:1 design factor.

Eagle Beam is designed to the conservative end of the BTH-1 framework — appropriate to portable, multi-jobsite, variable-operator service. Three times the rated load handled at yield stress, with documented margin beyond.

What is ASME BTH-1?→
Verification

Load-tested to 125% before shipment.

Every unit is load-tested to 125% of rated capacity using a calibrated load cell. The Certificate of Test — with the date, capacity, and verified result — ships with the beam. Critical for ports, utilities, nuclear, and any regulated worksite.

How load testing works→
The Eagle Beam Lineup

Two product lines. Matched to your crane.

eme makes Eagle Beam in two distinct product lines, each built for a class of portable crane. Pick the line that matches your equipment — capacity, spread, and beam profile are sized to the cranes the line is engineered to pair with.

3×6

Eagle Beam · Compact

1,000 – 6,000 lb up to 20 ft

For portable cranes in the 1,000–6,000 lb class. Compact profile, lighter beam at every spread.

Pairs with
  • eme gantries — 1100R, 2200R, 4400R, 6600R
  • eme davit cranes
  • Service truck cranes
  • Spider cranes (small)
  • Small jib cranes
3×12

Eagle Beam · High Capacity

1,000 – 10,000 lb up to 28 ft

For portable cranes in the 6,000–10,000 lb class. Deeper section for higher capacity and longer spreads.

Pairs with
  • eme gantries — 11000R, 22000R
  • Mid-capacity spider cranes
  • Larger service truck cranes
  • Similar portable cranes in the 6,000–10,000 lb class
Engineered For eme gantries · eme davit cranes · service truck cranes · portable gantries · mobile lifting frames · spider cranes · small jib cranes · monorails — rated to 10,000 lb.
Not For Crawler cranes · tower cranes · shipyard derricks — use steel spreaders rated to that equipment.
Standards & Documentation

The only third-party-certifiable claim is the one that doesn't apply.

The structural welds on most eme gantries and davits are produced under CSA W47.2 certification by qualified aluminum welders — the Canadian Welding Bureau credential for fusion welding of aluminum. Eagle Beam doesn't carry W47.2 because it has no welded joints in the load-bearing structure. That's the design, not an omission.

  • Built around ASME B30.20. The American Society of Mechanical Engineers standard for below-the-hook lifting devices. Governs marking, inspection, testing, and operation. Eagle Beam attaches between the crane's load hook and the load — the crane itself (a gantry or davit) is separate lifting equipment with its own crane standards; the Eagle Beam operates under B30.20 as the below-the-hook device.
  • Designed to ASME BTH-1 Category B with a 3:1 design factor on yield stress. The conservative end of the BTH-1 framework — appropriate to portable, variable-operator, multi-jobsite service.
  • All-bolted construction with SAE J429 Grade 9 (Grade L9) fasteners — 180 ksi minimum tensile strength, 145 ksi proof load. No welded joints in the load-bearing structure — by design, not by accident. CSA W47.2 doesn't apply because there are no production welds to certify.
  • 6061-T6 aluminum structural members. The standard alloy for portable aluminum lifting equipment. Aluminum Design Manual (ADM) design minimums are Fty = 35 ksi and Ftu = 38 ksi (typical mill-certified properties run higher — yield ~40 ksi, tensile ~45 ksi).
  • Load-tested to 125% of rated capacity with a calibrated load cell. Certificate of Test ships with every beam — capacity, test load, method, and date documented for any regulated worksite that requires it.
