The turning radius on a forklift is also known as the turning circle. This information is essential for a machinery driver to have. It gives the driver the information of how much space is needed to turn the forklift around. For instance, a tighter turning radius allows the machinery to successfully function in tight places and crowded areas, therefore enhancing the forklift's maneuverability. Operators who do not know this measurement can cause damage to the property or to the equipment.
Prior to checking the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Start the test with having the trained operator inside the cab to control the equipment's functions. A second person on the ground uses a hose or a spray bottle to wet the inside and outside of the model's wheels. Then, drive the machine in a whole 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 utilizing a tape measure after your measurement test has been completed. The watermark test begins 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 circle's opposite side. You can establish the inside turning radius by stretching the tape measure across the circle left by the inner tires. Next, 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 completed, next find the point on the pavement directly below. This point to the turning center indicates the machine clearance radius. As a rule, wall-to-wall turning diameter is two times the vehicle clearance radius.
