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 operator the information of how much space is required to turn the forklift around. Like for instance, a tighter turning radius enables the machine to successfully operate in crowded areas and restricted places, therefore enhancing the maneuverability of the lift truck. Operators who are not aware of this measurement may cause damage to the machine or to the property.
Before testing the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Begin 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 complete circle with the wheels turned to the maximum angle. Repeat the procedure once and continue if necessary to wet the wheels.
Measure the watermarks left by the tires with a tape measure once your measurement test has been done. The watermark test starts from the tire mark's midpoint to a similar point across the circle's diameter. 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 could determine 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 determine the turning radius. Be sure 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 machine in order to establish the wall-to-wall turning diameter. When this is completed, next locate the point on the pavement directly beneath. This point to the turning center indicates the clearance radius of the machinery. As a rule, wall-to-wall turning diameter is twice the clearance radius of the machine.
