7777 Veeder-Root Mechanical Mile/Kilometer Hubodometer

Description

Veeder-Root hubodometers record the distance or area covered by rolling stock, primarily commercial Over-The-Road trailers, large buses, trains, and agricultural equipment. Adjustments for rail include blocking off the 10th wheel.

Mechanical counters mount to the axle of a vehicle or trailer and count each axle rotation to track total miles/ kilometers/ acres/ hectares traveled.

The 7777 Series Veeder-Root Mechanical Hubodometer provides rugged, reliable operation for all applications. The die-cast zinc housing is hermetically sealed filled with inert gas and protected by a double O-ring. As the vehicle axle rotates, the entire hubodometer housing rotates. However, an eccentrically mounted weight remains stationary inside the device. The weight, or magnet, always points down as the body of the hubometer rotates around it, counting each rotation. Contrasting wheels on the hubodometer faceplate display the readout in real time.

The 7777 Series Veeder-Root Mechanical Hubodometer is also known as “the original hubodometer” and boasts features such as:
