The forklift's turning radius is also called the turning circle, which is essential information for the operator to have. It gives the operator the knowledge of how much space is required to turn the forklift around. For instance, a tighter turning radius enables the machinery to function successfully in crowded areas and restricted places, therefore improving the maneuverability of the forklift. Operators who are not aware of this measurement can cause damage to the property or to the machinery.
Make the necessary steering geometry alignment corrections before testing the turning radius. The test must begin with an operator trainer assisting inside the cab where they can help 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. Next, drive the machine in a whole circle with the wheels turned to the maximum angle. Repeat the procedure once and if necessary, continue to wet the wheels.
Once this measurement test has been accomplished, measure the watermarks left by the tires with a tape measure, from the midpoint of the tire mark to a similar point across the circle's diameter. For the outside turning diameter, measure the watermark left by the outside tires from the circle's one side to the opposite side of the circle. You could establish the inside turning radius by stretching the tape measure across the circle left by the inner tires. After that, divide these numbers in 2 in order to establish the turning radius. Be certain to note that the turning center is the midpoint of the circle's diameter.
To be able to establish the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the machinery. After this is completed, the next step is to locate the point on the pavement directly underneath. This point to the turning center indicates the clearance radius of the vehicle. As a rule, wall-to-wall turning diameter is twice the equipment clearance radius.
