LOCOMOTIVE LOAD BOX
The load box can be used to verify the performance of the diesel engine and generator group. It can also be a step-in trouble shooting. Being able to push the engine and generator to nominal power at a standstill can reveal problems otherwise invisible until a failure occurs with the locomotive in line.
A repeated complaint of the yard drivers is the engine souping. Souping occurs when oil is being thrown out through the engine exhaust. This happens when the engine has been running cold for too long. Varnish is deposited on the cylinder and prevents the piston segmentation from removing oil accumulation. Using the load box to bring the engine at high-working temperature will remove this varnish. Burning the varnish and creosote accumulation will produce many sparks. When uncontrolled, these sparks can create accidental fires.
Test various locomotive models with power settings
Load box power setting is related to the resistor values. Ohm’s law will limit load box usage. The design of the load box prevents inadvertent overcurrent or overvoltage of the locomotive circuit. The load box design prevents circuit opening during loading process as otherwise this would cause catastrophic damage to the generator.
Load box advantages
- Using a load box on souping engine prevents accidental brush fire
- Load box testing is safer than in line testing.
- Trouble shooting using a load box will deliver definitive results.
