The lift truck's turning radius is also called the turning circle, that is important information for the driver to have. It gives the operator the knowledge of how much space is needed to turn the forklift around. Like for example, a tighter turning radius allows the machine to successfully operate in restricted places and congested areas, thus enhancing the forklift's maneuverability. Operators who do not know this measurement may cause damage to the property or to the machinery.
Prior to checking the turning radius, check the steering geometry alignment and correct it if it requires adjustment. Begin the test with having the trained operator inside 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. After that, 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 begins from the tire mark's midpoint to a similar point across the diameter of the circle. 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. The inside turning diameter could be established by stretching the tape measure across the circle left by the inner tires. Then, 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 circle's diameter.
Drop a plumb line from the extreme outside radial extension on the vehicle in order to determine the wall-to-wall turning diameter. When this is accomplished, next find the point on the pavement directly beneath. This point to the turning center indicates the clearance radius of the machine. As a rule, wall-to-wall turning diameter is twice the machinery clearance radius.
