Measuring Wheels serve as rough checks on more accurate measurements and useful in reconnaissance & preliminary surveys. Measuring wheels are attached to a vehicle with a rear-mounted hitch, allowing longer distances to be measured while moving at speeds of up to 8 mph. Measuring wheels are used to detect the rail position. These wheels operate in forward and reverse. Measuring wheels are available to measure the length of cable run into a hole. These wheels feature ergonomic handles with dual triggers that operate braking and counter reset functions.
