Abstract: Methods, systems, and devices to obtain dimensions of an article or product in association with material handling vehicles are disclosed. A dimension detection device is installed in an enclosure and is used to acquire geometrical dimensions of the object in association with the vehicle. A predetermined dimension of the vehicle is subtracted from the overall detected dimension to determine the dimensions, including weight, of the product alone. One or more dimension detection devices may also be positioned on a mast or other portion of the material handling vehicle allowing the material handling vehicle to act as a mobile product dimensioning system.
