The forklift's turning radius is also referred to as the turning circle, that is essential information for the operator to have. It gives the operator the information of how much space is needed to turn the forklift around. For example, a tighter turning radius enables the machinery to successfully operate in crowded areas and restricted places, thus enhancing the maneuverability of the forklift. Operators who are not aware of this measurement can cause damage to the property or to the machine.
Prior to testing the turning radius, check the steering geometry alignment and correct it if it requires adjustment. Start the test with having the trained driver in the cab to control the machine's functions. A second individual on the ground uses a spray bottle or a hose to wet the inside and outside of the unit's wheels. Then, drive the machine in a whole circle with the wheels turned to the maximum angle. Repeat the procedure once and continue if necessary to wet the wheels.
When this measurement test has been accomplished, measure the watermarks left by the tires utilizing 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. Then, divide these numbers in 2 to be able to determine the turning radius. Be certain to note that the turning center is the midpoint of the circle's diameter.
Drop a plumb line from the extreme outside radial extension on the equipment in order to establish the wall-to-wall turning diameter. When this is completed, next find the point on the pavement directly underneath. This point to the turning center indicates the clearance radius of the machinery. As a rule, wall-to-wall turning diameter is twice the machinery clearance radius.
