These systems generally consist of a GIS/GPS-based vehicle tracking chipper system and the associated mapping display shredder software. GIS, or Geographic Information System, provides the mapping component. With the tracker devices installed attachment in vehicles, dispatchers can follow a vehicle''s location in real-time. When an incident occurs, controllers can quickly dispatch the vehicle nearest to chipper and shredder the incident.In the El Paso Fire Department, for instance, the GPS-powered automatic vehicle locator system tracks attachment the location of the department''s apparatus fleet. This system consists of a radio and chipper a GPS receiver/transceiver affixed to each fire apparatus. A signal from the GPS unit is transmitted to a satellite, the signal bounces back to earth, and the radio system tells the computer system exactly shredder where that unit is on a map attachment to within one meter of accuracy.

The EFI system contains chipper an electronic control unit that can monitor the equipment''s functions, including dash displays (engine temperature, speed hours); analog/digital inputs (vehicle incline sensor, safety interlocks, vehicle and/or shredder blade speed); diagnostics (air cleaner status, oil change intervals, operator safety warnings); and electronic attachment governor/throttle controls (ground speed control, cut height ''control).The 725 cc Command Pro 26 EFI produces chipper 41.6 lb.ft. torque at 2200 rpm, has a compression ratio of 9:1 and utilizes Kohler''s nickel-silicon shredder and attachment plated Power-Bore cylinders chipper for longer cylinder life.

The operation of the feed system is controlled by the patented Vermeer AutoFeed II system, shredder which is designed to monitor and regulate feed rates automatically. The system monitors engine rpm and regulates the amount of hydraulic oil flow to the feed roller motor, based on the engine speed. "It''s an engine-load sensing device," said Brent Bartels, project engineer at Vermeer. attachment "AS wood is fed into the cutting mechanism, chipper and shredder that slows the cutter disc down, which attachment loads the engine down so the engine speed is slowing down. If that were to continue, the engine would eventually stall.
