A boom stowed switch is a small sensor with one important job: telling the tracker whether the boom is resting in its cradle. When it is not, and the truck is moving, the platform sends an alert. We install boom stowed switches on bucket, crane, digger derrick and aerial trucks across Georgia, South Carolina, North Carolina, Tennessee, Virginia, Alabama, Florida and Mississippi.

It is a position switch mounted at the boom rest, the cradle the boom sits in when the truck travels. When the boom is down in the rest, the switch is closed or pressed. When the boom lifts out, the switch changes state. Wired into an input on the GPS tracker, it tells the platform exactly when the boom is up.
Many trucks already have a boom stowed indicator in the cab. We can sometimes use that existing signal after metering it. Where there is none, or it is not reliable, we install a dedicated switch.
The switch has to be mounted where the boom closes it every time without crushing it, protected from weather, road spray and debris. The cable runs along the body to the tracker on a protected path, sealed at every connection. We test by raising and lowering the boom and confirming each change on the platform.
On insulated booms, nothing is mounted on or wired along the insulated section. Chassis wire colors are in our Vehicle Wiring Database.
Bucket trucks, aerial lifts, digger derricks, knuckle boom cranes, rotator wreckers, grapple trucks, concrete pumps and any truck with a boom that could be left up. See PTO and equipment monitoring for each application.
Most fleet platforms let a manager set a rule: if the boom stowed input shows the boom out of its rest and the truck speed goes above a low threshold, send an alert. The alert can go to a supervisor by text, email or app notification, and it is logged with the time, location and driver.
Some fleets also add an in-cab buzzer or light tied to the same switch, so the driver is warned before anyone else is. The tracker record then shows whether the warning was acted on. Together, those two layers catch most boom-up driving before it turns into a strike.
This is one of the work truck and equipment applications we wire into GPS trackers. See all of them on our PTO and equipment monitoring page, and find wire colors for your truck in our Vehicle Wiring Database.
We wire PTO monitoring into trackers from all of these brands. Need heavy duty trackers for trucks or heavy equipment? Every brand below makes them, so pick yours and we install it.
Common questions
Yes, once a boom stowed switch is wired into a tracker input.
Sometimes. We meter it first and use it only if it is reliable.
