The lift truck's turning radius is also referred to as the turning circle, that is vital information for the operator to have. It gives the operator the knowledge of how much space is required to turn the lift truck around. Like for instance, a tighter turning radius enables the machine to successfully operate in restricted places and crowded areas, therefore enhancing the lift truck's maneuverability. Operators who are not aware of this measurement can cause damage to the property or to the equipment.
Before checking the turning radius, check the steering geometry alignment and correct it if it requires adjustment. Start the test with having the trained operator inside the cab to control the equipment's functions. A second individual on the ground utilizes a hose or a spray bottle to wet the inside and outside of the model's wheels. Then, drive the equipment in a complete 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 using a tape measure after your measurement test has been done. 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 outside tires from the circle's one side to the opposite side of the circle. The inside turning diameter can be determined by stretching the tape measure across the circle left by the interior tires. Then, divide these numbers in 2 to be able to establish the turning radius. Be certain 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 determine the wall-to-wall turning diameter. When this is completed, next find the point on the pavement directly underneath. This point to the turning center indicates the clearance radius of the machine. As a rule, wall-to-wall turning diameter is twice the clearance radius of the machinery.
