The use of the Avery electrodynamic machine has been extended to the balancing of wheelsets. The principal advantages are stated to be that a relatively unskilled operator can quickly and accurately determine the position and amount of correction required; and that good sensitivity is obtained without having to use delicate mechanical or electronic amplifiers. The balancing machine consists of a heavy base on which are mounted two adjustable pedestals and a driving head. On the top of the driving head is fitted the indicating head; this contains a wattmeter, four-position switch, sensitivity switch, plane potentiometers, calibration controls, and polarity switches. The arrangement of the indicating head is shown.
