The turning radius on a lift truck is also known as the turning circle. This information is important for a machine 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 allows the machinery to successfully operate in tight places and crowded areas, therefore enhancing the forklift's maneuverability. Operators who do not know this measurement could 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 needs adjustment. Start the test with having the trained operator in the cab to control the equipment's functions. Another individual on the ground uses a hose or a spray bottle to wet the inside and outside of the model's wheels. Then, drive the equipment in a whole circle with the wheels turned to the maximum angle. Repeat the procedure once and if necessary, continue 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 starts 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 circle's opposite side. You can determine the inside turning radius by stretching the tape measure across the circle left by the interior 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 machinery in order to establish the wall-to-wall turning diameter. When this is done, next find the point on the pavement directly below. This point to the turning center indicates the machinery clearance radius. As a rule, wall-to-wall turning diameter is twice the machinery clearance radius.
