A system for a pallet truck load wheel mechanism comprises a logic device (49) and first and second sensor arrangements (43, 46). The first and second sensor arrangements (43, 46) include first and second sensing fields that define first and second edges (41, 42) of an operability window (40), respectively. The logic device (49) has an operable state indicating that the load wheel mechanism can raise a pallet lifting device and an inoperable state indicating that the load wheel mechanism should not raise the pallet lifting device. The logic device (49) is initialized in the operable state and is configured to change to the inoperable state in response to each time the first sensor arrangement (43) detects an edge of a board intersecting the first edge (41) of the operability window (40) and to change to the operable state in response to each time the second sensor arrangement (46) detects an edge of a board intersecting the second edge (42) of the operability window (40).
