Built to Eliminate Downtime
Across the Chicagoland freight basins, unbilled driver hours, roadside breakdowns and out-of-service DOT violations cut straight into operating margins.
ENCINA POWER brings preventive maintenance to your terminal during off-hours and weekend dwell time. That means no deadhead miles to a shop, no drivers waiting on the clock and no unnecessary towing.
Unbilled Driver Downtime
Drivers sitting in a shop lobby on the clock instead of running loads.
Catastrophic Roadside Breakdowns
A DPF fault on I-80 at 2 a.m. turns into a tow, a late load and a customer asking questions.
Out-of-Service DOT Violations
Brake, lighting and tire defects that park a truck at a roadside inspection.
