The forklift's turning radius is also known as the turning circle, which is essential information for the operator to have. It gives the driver the information of how much space is required to turn the forklift around. Like for example, a tighter turning radius enables the machinery to work successfully in crowded areas and tight places, thus enhancing the maneuverability of the forklift. Operators who are not aware of this measurement may cause damage to the machine or to the property.
Make the necessary steering geometry alignment corrections prior to checking the turning radius. The test must begin with an operator trainer helping in the cab where they can assist to control the machine's functions. A second individual on the ground utilizes a spray bottle or a hose to wet the inside and outside of the model's wheels. After that, drive the equipment in a complete circle with the wheels turned to the maximum angle. Repeat the process once and continue if necessary to wet the wheels.
Measure the watermarks left by the tires with a tape measure when your measurement test has been completed. The watermark test begins from the midpoint of the tire mark to a similar point across the diameter of the circle. For the outside turning diameter, measure the watermark left by the exterior tires from one side of the circle to the opposite side of the circle. You can establish the inside turning radius by stretching the tape measure across the circle left by the inner tires. Then, divide these numbers in 2 in order to establish the turning radius. Be sure to note that the turning center is the midpoint of the diameter of the circle.
Drop a plumb line from the extreme outside radial extension on the machine in order to determine the wall-to-wall turning diameter. When this is accomplished, next locate the point on the pavement directly below. This point to the turning center indicates the clearance radius of the vehicle. As a rule, wall-to-wall turning diameter is twice the machinery clearance radius.
