Millwright Services

Millwright services for industrial plants: machinery installation, precision equipment setting, alignment, conveyor systems and equipment relocation, self-performed by certified millwrights on our own payroll.

Industrial Millwright Services

What millwright services cover

A millwright owns the machine. Other trades bring the piping, the steel and the power to it. The millwright puts the equipment on its foundation, holds it there, and brings its rotating parts into tolerance. On an industrial project that scope breaks into five parts:

  • Machinery installation. Receiving equipment, rigging it into position and setting it to the tolerances the manufacturer specifies.
  • Precision equipment setting and alignment. Leveling, grouting, and aligning shafts, couplings and drivetrains so connected components run true.
  • Conveyor and material handling installation. Setting sections, drives, pulleys and idlers, then truing the run end to end.
  • Equipment relocation and reinstallation. Disassembly, moving and resetting machinery inside a working plant or into a new one.
  • Realignment, rebuild and modification. Correcting alignment, replacing worn components, and modifying equipment that has outgrown its duty.

LMC self-performs all five. Millwright installations and conveyor systems are listed company specialties, and the millwrights who do the work are employees inside a workforce of more than 350.

The equipment our crews set

“Equipment” is where most millwright quotes go vague, so here is the published list. Setting and installation of major project equipment, with certified riggers and critical lift plans, covers:

  • Turbine skids, gas coolers and generators
  • Compressor intake and exhaust
  • Modular piping skids and gas conditioning skids
  • Lube oil coolers and filter separators
  • ESD systems
  • Data center skids and prefabricated buildings
  • Electrical equipment and battery backup systems — set and installed, with the electrical work itself partnered out

If your equipment is not on that list, the question worth asking is whether the weights, the lift points and the tolerances look like something on it. Most of the time they do.

Precision equipment setting, in the order it has to happen

Equipment setting is a sequence, not a lift. Each step holds the one after it, and most of the failures come from taking them out of order.

Rig and set. Weights, lift points and travel paths are confirmed before anything comes off the trailer. Equipment damaged on the day it arrives never fully recovers its service life.

Level. The machine is brought to its design plane, measured rather than eyeballed, and checked again after the mounting bolts are torqued to their documented values.

Grout. The baseplate is grouted so the foundation and the machine behave as one mass under thermal and dynamic load. Level today means nothing if the baseplate drifts, rocks or vibrates loose next year.

Align. Shafts, couplings and drivetrains are brought into tolerance by precision alignment, then re-checked after thermal growth once the equipment has run at temperature.

The order is the whole argument. Alignment carried out before grout has cured, or before piping strain has been relieved, is alignment that will not hold. Misalignment rarely stops a machine at startup. It takes the bearings and the seals out months later, in the middle of a production run, and the report blames the equipment.

Millwright installation of production machinery, conveyors and material handling

Not all millwright work sits in a mechanical room. The same trade installs production machinery, sets and aligns conveyor and material handling systems, and modifies or relocates equipment that no longer fits its footprint. Conveyor systems and millwright installations are listed together among LMC’s specialties for that reason: on most plants they arrive as one scope.

Conveyors punish a sloppy installation more visibly than almost anything else. Alignment has to hold across the whole run — drives, pulleys, idlers and transfer points all in agreement — or the belt wanders, spills product and wears itself out. Setting each section true and then truing the system end to end is slow work. It is still cheaper than replacing belting every quarter.

Heavy rail equipment is the same problem in a different shape. The project list includes the American Rock Salt salt car modifications, and industrial fabrication services at Dansville extend to locomotive repair, overhaul and modification through American Motive Power, which is AAR M-1003 certified and housed inside the same facility.

Equipment setting in data centers and behind-the-meter power

In a mission-critical building, setting quality turns into reliability. Cooling and power equipment runs continuously, so an alignment shortcut taken to protect a fast-track schedule comes back as vibration, a seal failure, or the downtime the facility was designed never to have.

LMC brings a millwright team for precision equipment setting and a project controls group to power generation stations and data centers, including modular data center skids fabricated in Dansville and set on site. Behind-the-meter generation adds a second wave of the same work on the customer’s side of the meter: natural gas piping installation, facility and balance-of-plant construction, and precision equipment setting and alignment.

Electrical is the one scope LMC does not self-perform; it is partnered out to electrical contractors. Mechanical and millwright scopes stay in house. If you are mapping those scopes against a mechanical package, the mechanical and millwright scopes in a data center are set out in detail separately.

Millwright work on compressor stations and process plants

Most of this crew’s hours are in energy infrastructure, and that is where the tolerance discipline came from. Millwright installations sit inside LMC’s process piping scope on natural gas compressor stations, meter and regulator stations, pump stations, and modular process skids across oil and gas — Wantage NJ 325 Compressor Station, Perulack Compressor Station and Third Street GTS Distribution among them.

The same crews set and align rotating equipment in food manufacturing facilities, on water infrastructure, and on environmentally sensitive piping systems. Documentation-heavy, schedule-driven work is the normal case here, not the exception.

The bench behind a setting crew

An equipment-setting crew is only as good as what surrounds it. LMC employs more than 350 tradespeople, and a millwright on site is working next to API 1104, ASME, AISC and AWS certified welders and fabricators, NACE certified painters and blasters, licensed and NCCCO trained crane operators and riggers, carpenters, an HVAC service group, and engineering staff.

The company also runs more than 300 pieces of its own equipment — rough terrain and crawler cranes, excavators and dozers, industrial telehandlers, loaders and haul trucks. When the crane is on the company yard in Dansville instead of a rental branch calendar, the set date moves when your project moves, not when a counter has availability.

LMC has been doing this since 1982, when Lawrence Mehlenbacher founded it as a mechanical contractor specializing in process piping. The millwright and alignment work grew out of that trade rather than being added beside it.

Who holds the crane on your lift

Setting a turbine skid, a generator or a gas cooler is a rigging problem before it is an alignment problem. When the lift is subcontracted, the two crews most responsible for your equipment answer to different companies, and the handoff between them is where damage and delay live.

LMC self-performs both, with certified riggers and critical lift plans. Rigging practice follows the ASME B30 standards and crane operator certification is verifiable through NCCCO. The detail of how a lift is planned, inspected and executed sits on the rigging services page.

Welding, fabrication and the shop behind the field crew

Millwright work goes faster when the parts fit. Guards, frames, skids, supports and replacement steel are fabricated indoors at the fabrication facility in Dansville, New York — 700,000 square feet of covered space on 88 acres, 55 of them for storage — then arrive ready to bolt in.

Shop capacity is what makes that practical. Overhead cranes run to 10, 15, 35, 50 and 150 ton hooks, with over 750 tons of total facility lifting capacity, and the site is served directly by the Rochester and Southern short line railroad, so a large assembly ships by rail instead of being cut down to fit a truck and field-welded back together.

Welding and fabrication are self-performed alongside the millwright scope, which matters when a baseplate needs modifying or a support needs to be built at the machine. Custom metal fabrication and structural steel fabrication come out of the same shop and the same certifications.

Millwright services inside a mechanical package

Millwright scopes rarely arrive alone. They come attached to piping, structural steel, or a full mechanical installation. Where LMC carries the surrounding work as an industrial mechanical contractor, it also self-performs hydro and pneumatic testing, torquing and tensioning to documented values, tubing and instrumentation, mechanical detailing, and painting and coating.

That matters at the tie-in. Pipe spool fabrication done in the shop to the same dimensions the millwright is setting to removes the field adjustment that pulls a machine back out of alignment. Where the scope widens into civil, structural and building work, it is covered under industrial construction services.

One contractor across those scopes means one schedule, one set of documentation, and one company to call when a tolerance is missed.

What to ask a millwright contractor before you award the scope

Are your millwrights employees or subcontractors? It decides whether your commissioning date depends on another company’s availability. Millwright work sits at the end of the mechanical sequence, which makes it the scope most exposed to everybody else’s delays. A booked subcontract crew is gone when the window slips.

Who does the rigging? If the lift and the set are held by different companies, the seam between them is yours to manage.

What else can you self-perform? Every scope handed to another trade is another schedule you cannot see.

Can you name the bench? Certified millwrights, licensed crane operators and certified welders on one payroll are a verifiable answer. “We have access to crews” is not.

What to send to get a millwright scope priced

A useful quote turns on five things. Send what you have of them and the gaps get asked about rather than assumed:

  • The equipment list. Make, model, weights and the manufacturer’s installation tolerances, or the data sheets if the equipment is not selected yet.
  • Foundation and baseplate detail. Drawings or photographs of what the equipment is landing on, and whether grouting is in your scope or ours.
  • Site access and the lift. Travel path, rigging restrictions, and whether the work is in a live plant or an open building.
  • The schedule window. The set date, the commissioning date, and which trades are working around you.
  • Scope boundaries. Whether you want setting only, or setting with the piping, steel and testing attached.

Common questions about millwright services

What does a millwright do? A millwright installs, levels, grouts, aligns, maintains and relocates industrial machinery. The scope runs from rigging a package onto its foundation to bringing a conveyor drive into tolerance, and it covers the measurements that decide how long the equipment lasts.

What is the difference between a millwright and a rigger? A rigger moves the load; a millwright makes the machine run. Rigging is often part of a millwright scope, and millwrights plan and execute lifts, but the trade is defined by what happens after the pick — the leveling, grouting and precision alignment.

Do millwright services include conveyor systems? Yes. Conveyor and material handling installation is core millwright work: setting sections, aligning drives, pulleys and idlers, and truing the system end to end. Millwrights also modify, extend and relocate existing conveyor systems.

Does LMC self-perform millwright work or subcontract it? LMC self-performs it. Certified millwrights are employees inside a workforce of more than 350, working with the company’s own welders, crane operators, riggers and painters, and more than 300 pieces of owned equipment. Electrical is the scope that is partnered out.

Can you relocate equipment inside a working plant? Yes. Disassembly, relocation and reinstallation are part of the scope, including realignment and the modification or replacement of worn components.

Where does LMC perform millwright services? Crews mobilize from 9431 Foster Wheeler Road, Dansville, New York, and work on industrial projects across the United States, concentrated in energy infrastructure, power generation, data centers, food manufacturing and water infrastructure.
