Abstract
A pallet truck has a brake release mechanism. The pallet truck has a break release mechanism operably coupled to a brake for stopping rotation of a drive wheel. The brake release mechanism includes a brake release sensor and a profile feature that is detectable by the brake release sensor. The profile feature is fixedly coupled to a pivot shaft of a tiller arm of a tiller, and configured to rotate with the pivot shaft as the tiller arm is pivoted. The brake release sensor is positioned adjacent to the pivot shaft and configured to output a signal that causes the brake to release when the profile feature is detected.
