The forklift's turning radius is also called the turning circle, which is vital information for the operator to have. It gives the operator the information of how much space is needed to turn the lift truck around. Like for instance, a tighter turning radius enables the machine to successfully function in crowded areas and tight places, therefore enhancing the maneuverability of the lift truck. Operators who do not know this measurement can cause damage to the machinery or to the property.
Prior to testing the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Start the test with having the trained operator in the cab to control the machine's functions. Another person on the ground uses a hose or a spray bottle to wet the outside and inside 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 if necessary, continue to wet the wheels.
Once 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 diameter of the circle. 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. The inside turning diameter could be established by stretching the tape measure across the circle left by the inner tires. Next, divide these numbers in 2 to be able to establish 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 machinery in order to determine the wall-to-wall turning diameter. Once this is accomplished, next locate the point on the pavement directly beneath. This point to the turning center indicates the machinery clearance radius. As a rule, wall-to-wall turning diameter is twice the machine clearance radius.
