The lift truck's turning radius is also referred to as the turning circle, which is essential information for the operator to have. It gives the driver the information of how much space is needed to turn the lift truck around. Like for instance, a tighter turning radius allows the machine to function successfully in tight places and crowded areas, thus improving the maneuverability of the forklift. Operators who are not aware of this measurement may cause damage to the property or to the machine.
Before checking the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Begin the test with having the trained driver inside the cab to control the equipment's functions. Another person on the ground uses a spray bottle or a hose to wet the inside and outside of the model's wheels. After that, drive the machinery 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 using 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 circle's diameter. For the outside turning diameter, measure the watermark left by the exterior tires from the circle's one side to the circle's opposite side. You could establish the inside turning radius by stretching the tape measure across the circle left by the interior tires. After that, divide these numbers in 2 to be able to determine the turning radius. Be certain to note that the turning center is the midpoint of the diameter of the circle.
To be able to establish the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the equipment. After this is accomplished, the next step is to find the point on the pavement directly beneath. This point to the turning center indicates the clearance radius of the vehicle. As a rule, wall-to-wall turning diameter is twice the clearance radius of the machinery.
