The Load Can't Switch
Trailers Halfway to the Site
Inspections built for each trailer type open work orders when an item fails, and overdue PMs
surface before dispatch, so the shop fixes trouble in the yard before a permitted load leaves.
Where Heavy Haul
Maintenance Breaks Down
Construction runs on the job schedule, and the schedule runs on the machines. When service lives
on calendars and phone calls, one missed filter can stall a whole crew.
The annual inspection on one
trailer lapses. DOT finds it.
A ramp cylinder weeps in the
yard. Nobody writes it up.
Two brakes out of adjustment.
The rig goes out of service.
The load waits on the shoulder.
So do the escorts.
The repair history takes half an
hour to find.
Same trailer, same leak, next
permitted move.
Tractor and Trailer Cleared
Before the Move
Squarerigger keeps inspections, PMs, parts, and repair history for each tractor, trailer, and dolly in one record.

Frequently Asked Questions
Does your tanker fleet maintenance software keep tractors and tank trailers in one system?
Yes. Tractors and tank trailers each carry their own asset record, inspection checklists, PM schedules, and repair history. McNay Truck Line runs its tractor shop and trailer shop in Squarerigger.
How do we keep cargo tank test dates from slipping?
Set each recurring inspection on the interval it needs, and automated reminders flag monthly, quarterly, and annual work before it comes due. Walk through your test schedule during the demo.
Our TMS already tracks equipment. Why add a shop system?
Squarerigger runs the shop: inspections, repairs, parts, and outside work. With McLeod, it pushes service-due alerts so dispatch avoids assigning loads to equipment due for service.
Can reports from outside inspectors and test shops live on the unit?
Yes. Outside work orders tie to the asset with labor, parts, invoices, and documents attached. Smart Fill fills in the details from vendor PDFs.
Can we produce inspection records at an audit or roadside stop?
Yes. Inspections save as time-stamped records in the cloud, and compliance reports generate on demand. Registrations and certifications sit in the same archive with renewal alerts.
Will our trailer techs use it?
McNay Truck Line's trailer shop picked it up quickly. Techs work from tablets in the shop, and every rollout includes role-based training.
