The turning radius on a lift truck is also referred to as the turning circle. This information is important for a machinery driver to have. It gives the operator the knowledge of how much space is required to turn the lift truck around. Like for example, a tighter turning radius allows the machine to successfully function in restricted places and congested areas, therefore enhancing the forklift'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 needs adjustment. Begin the test with having the trained driver in the cab to control the equipment'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. After that, drive the equipment in a complete circle with the wheels turned to the maximum angle. Repeat the procedure once and if necessary, continue to wet the wheels.
Measure the watermarks left by the tires utilizing a tape measure once your measurement test has been completed. 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 outside tires from one side of the circle to the circle's opposite side. You can establish 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 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 vehicle in order to determine the wall-to-wall turning diameter. When this is done, 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 clearance radius of the vehicle.
