The reefer tank is not the tractor tank
An empty reefer fuel tank stops the unit while the tractor still has fuel.
The refrigeration unit carries its own fuel tank, separate from the tractor. I ask the driver to look at that tank, or at the unit’s fuel gauge, before I record a mechanical failure. A tractor with half a tank and a reefer tank on empty will sit on the shoulder with a silent unit and a climbing box. The repair is fuel, then a restart, then a watch on the pull-down.
Drivers who just took a relay trailer sometimes never opened the reefer tank. I treat “I don’t know the fuel” as unknown, and I ask them to check if they can do it safely where they are parked. A fuel check on a live lane is not worth the reading. In that case the shop is told the tank was not verified.
Low fuel can also sit next to a real fault. A unit that starved, shut down, and then shows an alarm still needs the code copied. I do not clear the alarm line because the tank was empty. The shop may find a sensor complaint that appeared after the restart. Both facts stay on the ticket.
Fuel is outside the crew-day math. Crew-days estimate the hours of unit work once a tech is on the trailer. Putting diesel in the reefer tank is not a compressor job, and I do not fold it into the shop-hour figure the planning tool uses.
The note "The reefer tank is not the tractor tank" starts from the line already on the ticket. The refrigeration unit carries its own fuel tank, separate from the tractor. I ask the driver to look at that tank, or at the unit’s fuel gauge, before I record a mechanical failure. A tractor with half a tank and a reefer tank on empty will sit on the shoulder with a silent unit and a climbing box. The repair is fuel, then a restart, then a watch on the pull-down. A reefer call starts with the temperature on the box and the setpoint, not with the word broken. Umbel records both, plus whether the load is still inside, then holds one shop. Umbel reads that back before a time is offered.
What the company sees for "The reefer tank is not the tractor tank" is the next line of this note. Drivers who just took a relay trailer sometimes never opened the reefer tank. I treat “I don’t know the fuel” as unknown, and I ask them to check if they can do it safely where they are parked. A fuel check on a live lane is not worth the reading. In that case the shop is told the tank was not verified. Reefer crew-days at /reefer-trailer-service-hours is a planning figure. It is not a bill, and it is not a promise the visit is already staffed.
"The reefer tank is not the tractor tank" does not send ReeferTrailerAndColdChainEmergencyDispatch out to do the work. Low fuel can also sit next to a real fault. A unit that starved, shut down, and then shows an alarm still needs the code copied. I do not clear the alarm line because the tank was empty. The shop may find a sensor complaint that appeared after the restart. Both facts stay on the ticket. One paid company gets the request. The street address stays off the offer until that company claims it. Starter is $299 a month, with unlimited seats. Every plan includes a 14-day free trial with 100 AI minutes, no credit card required.
After "The reefer tank is not the tractor tank" is on the job, Umbel still keeps the callback to one company. A reefer call starts with the temperature on the box and the setpoint, not with the word broken. Umbel records both, plus whether the load is still inside, then holds one shop. Passing the request is allowed. A group text is not the dispatch. The record stays on the job the company opens in the morning.
A caller asking about "The reefer tank is not the tractor tank" still has to leave the facts Umbel asks for on the first ring. A reefer call starts with the temperature on the box and the setpoint, not with the word broken. Umbel records both, plus whether the load is still inside, then holds one shop. If the office is closed, those facts have to be on the ticket before the morning crew starts. The company that claims the request confirms the window.
The planning figure behind "The reefer tank is not the tractor tank" is there so the board matches what the caller heard. Reefer crew-days does not price a finished job and does not certify the work. ReeferTrailerAndColdChainEmergencyDispatch is dispatch software. A local company fulfills the visit, and the timing depends on that company's capacity.
