Plant Relocations
Moving an entire production line from one building to another — or one bay to the next. Portable gantries roll the equipment through corridors and doorways a truck crane can't reach.

When the Building Won't
Let a Truck Crane In.
Typical Capacity
4,400 – 22,000 lb
Setup
1–4 people · forklift-assisted on big units
Headroom
Configurable to ceiling height
Mobility
Rolls fully loaded on prepared surfaces
Specialty riggers and machinery movers work in spaces truck cranes don't fit, forklifts can't reach, and overhead cranes don't exist. The lift has to happen through a doorway, around a column, under a duct, or in a building where the only point of access is the freight elevator. eme portable aluminum gantries — 4,400 to 22,000 lb capacity — were built for exactly that constraint. The 22000 Series is eme's flagship 10-tonne portable aluminum gantry — one of the highest-capacity portable aluminum gantries available.

Typical Lifts
What Specialty Riggers Actually Move.
Six categories cover most of the moves a specialty rigging firm books. The constraint is almost always the same: the lift has to happen in a space the load came in through, and a truck crane wasn\'t a viable answer.
Machine Tool Positioning
CNCs, presses, EDM machines, large lathes — set on the leveled pad to alignment tolerance the rigger's plan calls for. The gantry sets the machine, then rolls back out without leaving structural marks.
Low-Headroom Lifts
Drop ceilings, overhead piping, structural beams — anywhere the ceiling height is under 12 ft and a chain hoist alone won't pick the load. eme gantries assemble to the available headroom.
Multi-Stage Hand-Offs
Truck crane sets the load on a temporary cribbed pad, the eme gantry picks it up and rolls it through the building, then sets it on the final pad. Two cranes, one continuous lift plan, no re-rigging.
Confined-Space Extractions
Removing equipment from a bay or pit where it was installed before the surrounding walls went up. The gantry assembles around the load and lifts it out vertically.
Press & Die Handling
Stamping press setups, die changes, fixture removals. The 22000 Series — eme's flagship 10-tonne portable aluminum gantry — is built for many higher-capacity loads in constrained spaces where conventional lifting equipment cannot practically reach.

The Equipment Most Rigging Firms Run.
Riggers tend to skew toward the larger end of the eme line — 6,600 lb is the workhorse, 11,000 lb is the standard for industrial moves, 22,000 lb is what closes deals the competition can't.
11000 Series Gantry
11,000 lb
Lift-eye range
106 – 154 in
8'10" – 12'10"
The 5-tonne rigger's standard — fits through most industrial doorways assembled, rolls the load to position on prepared surfaces. Available in R-15 and R-25 (longer beam) configurations.
See series→22000 Series Gantry
22,000 lb
Lift-eye range
97 – 139 in
8'1" – 11'7"
eme's flagship 10-tonne portable aluminum gantry. 22,000 lb capacity in a configuration that fits where a truck crane won't. Lift range trades some height for the additional capacity headroom.
See series→6600 / 8800 Series Gantry
6,600 – 8,800 lb
Lift-eye range · family
106 – 216 in
8'10" – 18'
The 3-tonne and 4-tonne family — three variants on the same chassis architecture. The 6600R-15 is the standard rigger's configuration; the 6600MAX-15 and 8800MAX-15 are ultra-tall builds for taller machinery, multi-tier installs, and lifts that need the extra lift-eye reach. All three share a trolley family with the 11000.
Variants in this family
- 6600R-15 6,600 lb 106 – 154 in Standard rigger configuration
- 6600MAX-15 6,600 lb 136 – 216 in Ultra-tall · same capacity
- 8800MAX-15 8,800 lb 136 – 216 in Ultra-tall · 4-tonne capacity
Lift-eye range = min / max height to the lifting shackle. Values shown are for standard rigging configurations (R-15, R-25). Taller MAX and HELI variants are available with extended lift envelopes — see the individual series page for the full range.

Rigging Work, in the Spaces It Happens.

Standards, Welding Certification & Testing
The Documentation a Rigging Lift Plan Demands.
OSHA requires a crane to be proof-load tested to 125% of rated capacity before it is placed into service — an obligation on the employer putting the crane to work. eme completes that proof test on every gantry as part of its quality-control process, so each one ships with an engineer-stamped drawing, a Certificate of Test at 125% of rated capacity, and a documented load path — the documentation a rigging lift plan or owner\'s safety review may request, with the pre-service proof test already done. Gantries are engineered to applicable ASME and CSA lifting requirements and welded under CSA W47.2 certification by qualified aluminum welders.
