The turning radius on a forklift is also referred to as the turning circle. This information is important for a machine driver to have. It gives the driver the knowledge of how much space is required to turn the lift truck around. For instance, a tighter turning radius allows the equipment to function successfully in congested areas and restricted places, thus enhancing the forklift's maneuverability. Operators who are not aware of this measurement can cause damage to the property or to the machine.
Make the necessary steering geometry alignment corrections prior to checking the turning radius. The test must begin with an operator trainer helping in the cab where they can assist to control the machine's functions. Another individual on the ground uses a spray bottle or a hose to wet the outside and inside of the model's wheels. Then, drive the machinery in a whole circle with the wheels turned to the maximum angle. Repeat the process once and if necessary, continue 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 begins 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 circle's diameter.
Drop a plumb line from the extreme outside radial extension on the vehicle in order to establish the wall-to-wall turning diameter. When this is accomplished, next locate the point on the pavement directly underneath. This point to the turning center indicates the equipment clearance radius. As a rule, wall-to-wall turning diameter is twice the equipment clearance radius.
