Millwright Business Insurance · Independent agency
A millwright’s largest exposure is not the work site itself. It is the customer’s machine, hanging in your rigging or rolling on your skates, worth more than anything you own. We insure millwright contractors, riggers and machinery movers with that machine in mind, along with the shop, trucks and crew that take the work from plant to plant.
Monday’s job might be a press on a new foundation, Thursday’s a bearing change during a shutdown and Saturday’s a line on its way to another building. An underwriter prices the whole calendar rather than one job, and our millwright insurance program is quoted the same way: every kind of work your crew takes on, on one application.
Presses, conveyors, pumps, compressors, turbines and packaging lines brought onto a foundation, leveled, grouted, anchored and aligned to the tolerance the owner’s engineer wrote down. The machine belongs to someone else, it can be worth more than your whole fleet, and it is in your hands from the moment it leaves the truck until it runs.
Disconnecting a line, skating it out through a door that was framed for something smaller, trucking it across town or across a state line, and standing it back up in a new building. Every step has a different exposure: the floor you roll across, the load on the trailer, the lift at each end and the reconnection that has to work on the first start.
Gantries, hydraulic jacks, toe jacks, skates, chain falls and cranes you own or rent, used to pick, turn and land a load the customer cares about. Rigging is where a single moment decides the claim: a sling angle, a pick point or a soft floor under an outrigger.
Scheduled outages and emergency calls inside a running plant: bearings, couplings, gearboxes, shafts and seals replaced on a clock, overnight at times and beside other contractors. The plant measures the outage in lost production, and that is the number its lawyers will reach for when something you touched fails afterwards.
Base plates, shims, stands, guards, platforms and supports cut, fitted and welded on site so the machine you are setting sits where it should. It is fabrication in service of an installation, done with a torch and a welder in someone else’s building, and it brings hot work into the conversation with every plant you enter.
Six policies, six different losses. Two do the heavy lifting here: general liability when an accident on the job hurts someone or damages something nearby, and professional liability when a setting or a plan you signed off on proves wrong.
Injury and damage to others
A plant employee hurt under a load, a forklift dented by a skate, a polished floor gouged on the way to the foundation: injury and damage to people and property around your work. Its exclusions bite on the machine you are moving, so read that wording first.
The setting that was off
Claims that your judgment, specification or workmanship caused a loss with no accident behind it: an alignment that wears a coupling early, an anchoring plan that lets a frame walk, a relocation layout that cost the owner a week. A liability policy is written for accidents; this one is written for the advice and precision the owner paid you for.
Your shop and the customer’s machine
Your building and its contents if you own the shop, plus the section of this program the trade turns on: riggers’ liability, contractor’s equipment and installation floaters, the coverages that answer for the customer’s equipment while it is in your care and for your own tools wherever they travel.
The crew under the load
Medical bills and lost wages for a crew member hurt on the job, with employer’s liability behind it if the injury turns into a lawsuit. Millwright injuries have their own shape: hands caught at a pinch point, backs strained on a jack, falls from a mezzanine or platform, burns from field welding.
The trucks and trailers
The pickups, service trucks, tractors and lowboy or drop-deck trailers the business owns or leases, plus hired and non-owned auto when a rental or an employee’s own truck goes to work. Ask how the policy handles the load riding on the trailer, because the auto policy and the cargo question are separate answers.
Limits a plant asks for
A layer above general liability, commercial auto and employer’s liability that starts paying when one of them runs out. Plants write limits into contractor agreements, and when those limits are higher than the base policies carry, the umbrella is what lets a millwright company sign.
Where the gaps open. General liability faces outward, at people and property near the job. Property insurance faces inward, at your shop and your tools. The customer’s machine sits between the two, and it is the reason a millwright program needs the riggers’ and floater coverage that general liability does not carry.
The worst day in this trade is the day a customer’s machine is damaged while it hangs from your rigging, rolls on your skates or sits half-anchored on its foundation. For those hours the machine is under your control, and control is the word a general liability policy turns against you.
Two exclusions in the standard commercial general liability form do the damage. The first removes cover for property in your care, custody or control. The second removes it for the particular part of any property you are working on, when your work is what damaged it. Picture a compressor slipping off a set of skates, a gearbox swinging into a column during a pick, or a spindle knocked out of true while you level its base. Each is the customer’s property, in your hands, mid-operation, so general liability is not the policy that pays. Riggers’ liability and an installation floater are written for exactly that moment, and the property insurance page’s riggers’ section sets the two side by side.
Moving a heavy machine through a finished building puts the building at risk before the machine is set. Polished concrete cracks under a point load, a dock leveler bends, a sprinkler head meets a mast. That damage is to property you are not working on, so it sits closer to what general liability is written for, and it is worth walking the route before the move with the plant’s own people.
An installation can look perfect on the day and fail on the schedule of a bearing. A shaft run slightly out of line, a soft foot under a motor, a grout pour that settles: the claim arrives as worn parts and a production line that stopped, with no accident anyone can point to. That is professional liability’s ground, and it is why a millwright who signs off on tolerances should ask for it.
Pinch points, dropped loads, a jack that kicks, a fall from a mezzanine during a shutdown, a burn from field welding. Each one is a workers’ compensation claim, and the plant will ask to see that coverage before your crew enters.
Field fabrication brings a torch and a welder into buildings full of dust, oil and stored material. A plant can require a hot work permit, a fire watch and proof of liability coverage before the first arc is struck, and a fire that starts from your spark is a liability loss that can reach well past the area you were working in.
A lowboy carrying a machine across a state line is an auto exposure and a cargo exposure at once. The auto policy answers for the crash; the machine on the deck needs its own answer, from a floater or a cargo form. Ask about both before the haul, not after the claim.
Before your crew is badged into a plant, someone in its purchasing or safety office hands over the insurance terms of the contract: additional insured status for the plant, your insurer giving up its right to recover from the plant, your coverage responding ahead of the plant’s own, and a stated limit for each line. Read it while you are still pricing the job. A missing endorsement found after the bid is won turns into a delay at the plant gate, while one found during bidding is a line on the agent’s worksheet.
Longer answers belong in the guides. They cover pricing for a millwright account, where a riggers’ form ends and a floater begins, and how to read a plant’s insurance requirements one line at a time; Nate Jones, CPCU, signs off on each before it is published.
The agency is licensed to place this coverage in every state except Alaska and Hawaii. Relocations and shutdowns take crews across state lines, so give the agent the full list of states you work in; the policies need to follow the crew wherever it goes:
Riggers liability answers for damage to property you do not own while you are lifting, moving or setting it: the press that drops off the skates, the gearbox that swings into a column. A millwright company that handles a customer’s machine needs an answer to that exposure, and riggers liability is one of the forms that gives it. It is written beside general liability, not inside it, so ask for it by name.
Probably not, and two exclusions are the reason. The standard general liability form takes coverage away for property you have in your care, custody or control, and for the part of a property your work is being performed on. A customer’s machine in your slings or on your skates fits both descriptions. The forms written for that loss are riggers liability and installation floaters.
Read the rental agreement before the lift. Some rentals put the operator and the load on the crane company; others make your firm responsible for the rigging, the signals and the load even with their operator in the seat. The answer decides whether your own riggers’ coverage has to respond, and whether the rental company needs to be named on your policy.
An umbrella or excess liability policy, sized to the contract. A plant’s requirements can name a general liability limit, an auto limit and an employer’s liability limit, then an umbrella limit above them. The umbrella has to sit over every policy the contract lists, so give the agent the full requirements page, not a summary.
Your own tools sit outside general liability, which is written for other people’s property. The coverage that follows jacks, skates, gantries, laser alignment kits, welders and the gang box from shop to plant and back is contractor’s equipment, an inland marine form. Rented equipment can be scheduled too, which matters when a rental agreement makes you answerable for it.
It needs property coverage written for the building and what is inside it: the bay, the overhead door, the stock of steel and the tools that stay home. A policy for your trucks or your liability does not cover the building. If a loss closes the shop, business income coverage can carry the payroll and bills while you rebuild.
Proof of insurance in the form of a certificate, plus whatever conditions the contractor agreement attaches: being added to your policy as an additional insured, a promise that your insurer will not pursue the plant after a claim, coverage that answers before the plant’s own, and a set limit on each line. Every one of those conditions is an endorsement, added to the policy itself; the paper the plant files away only reports them. That is why the requirements page belongs in your first conversation with the agent.
Nate Jones, CPCU, founded Wexford Insurance, LLC, an independent agency in Greenwood, IN, and Millwright Business Insurance is the part of it that works with millwright contractors. No insurance company owns the agency or sets its shelf. The agent’s job is to describe your crew, your lifts and your shop accurately and to put that description in front of the markets that want it.
Our panel reaches 17+ insurance markets.
No single market writes every millwright account. An underwriter decides from the lifts and moves you take on, whose machinery is in your care, the tools and trailers on your schedule and your history of claims, so the agent matches your account to the markets whose appetite fits it.
