Heavy Lift and Plant Maintenance

Planned maintenance windows

Plants schedule maintenance shutdowns months ahead, and crane work during that window is often the most time-sensitive part of the job, every extra hour the crane sits idle costs the plant money. Booking early and locking in the crane class, the operator, and the rate structure (including overtime for a window that runs around the clock) matters more here than almost any other job type.

If your maintenance window needs a crane on standby for several days with uncertain exact lift times, say that clearly when you request a quote so the company can price it as standby time versus active lift time.

Industrial equipment moves

Replacing a process vessel, a large pump, an HVAC rooftop unit at a plant, or electrical equipment all fall into this category. These jobs tend to need higher ton class cranes and a more detailed lift plan, including a check of overhead obstructions, underground utilities, and ground bearing capacity near the setup location.

The Port of Catoosa handles project cargo in this weight class regularly, including refinery heaters and cracking tower components, so companies that work the port corridor are used to this kind of planning.

What to line up ahead of time

Confirm the crane class against the real weight and reach, not an estimate, get the overtime and fuel surcharge rate in writing for a job likely to run long, and plan for any City of Tulsa right-of-way permit if the setup area touches a public street. See the cost guide and the permits and ground prep guide.

Coordinating with a plant's own schedule

Plant maintenance work rarely happens in isolation, your crane crew is usually one piece of a larger schedule involving the plant's own maintenance staff, other contractors, and a shutdown timeline that does not bend easily. Give the crane company as much lead time as you have on the real window, not just an ideal date, and flag anything that could push the schedule, permitting delays, parts on backorder, weather.

A crew that knows the maintenance window might slip can plan their other bookings around it. One that finds out at the last minute may not be available when you actually need them.

Site access for larger equipment

Heavy lift jobs often involve equipment coming in on a separate low-boy trailer, which needs its own path into the site that may be wider or require more clearance than the crane itself. Walk the route from the plant entrance to the lift location and check for low overhead clearances, tight gate widths, and any weight-restricted pavement or bridges before the day of the move, not after a truck is already stuck at the gate.
