What happened to the automatic detection.? I assume that if it was customary to leave the tractor unattended with the engine running it was equipped with it for exactly that circumstance.? If it wasn’t so equipped then all bets were off. The fire suppression system would be a paperweight.The issue when the tractor that I dealt with burned was that a steering hose failed at the interface of the hose and the fitting while the machine was sitting with no operator in it and was idling away. Basically the machine was used five minutes at a time and then left running for up to three quarters of an hour with no one in the cab. How do we know what happened. Because I pulled the product link file and found a loss of steering pressure. The fault showed for approximately 5 minutes and then all the electrical system went dead. The hose that failed was the outlet from the steering pump and it shot a fine spray over to the bottom of the cab floor plate and onto a bunch of electrical connections. It was at night and no one saw the smoke. I was told the operator came out and saw the machine wasn't running and then hit the suppression system. The fire was mostly already out because the oil stopped misting when the engine died and the hydraulic tank was nearly out of fuel. The machine was rebuilt and put back into service about two months later.
Caught fire under cab on top of transmissions. Burned fuel line off.A fire suppression system installed and it still burned to the ground.? I'd be interested to hear the story behind that one.
All the landfill equipment i worked on was automatic or manual. Had a wire strung all around machine if fire burned it in 2 or anything broke it it went off, the wood grinder had thermal sensors on it. Older system.I don't recall seeing any suppression system with automatic initiation. All I've had to be around required the operator to pull a pin and push a big red button.
Same here. Everything we run is automatic detection & actuation. Before setting the system off the control will sound an audible warning to the operator that an abnormal heat signature has been detected. He generally has 15 seconds (I think from memory) to press a button cancelling the actuation otherwise the whole shooting match discharges. if there is a fire it gives him the same length of time to get the machine stopped, drop any raised equipment, trans in neutral, park brake on, and kill the engine before everything is submerged in a ton of white powder.All the landfill equipment i worked on was automatic or manual.

aka the Hell Hole. It's bad enough in our application if there is any accumulation of oil or grease under there. I can't imagine what it would be like with that compartment full of sawdust on top of a hot converter, transmission and hydraulic pumps.Sawdust gets up under there and cooks till it ignites.
Mechanic now take out floor and clean. We also just put nozzels with quick connect for air or water to clean by operators.
