The turning radius on a lift truck is also known as the turning circle. This information is essential for a machine driver to have. It gives the operator the information of how much space is needed to turn the forklift around. For example, a tighter turning radius enables the machinery to successfully work in restricted places and congested areas, thus improving the lift truck's maneuverability. Operators who are not aware of this measurement could cause damage to the equipment or to the property.
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 machine's functions. A second individual on the ground uses a hose or a spray bottle to wet the inside and outside of the model's wheels. Next, drive the equipment in a whole circle with the wheels turned to the maximum angle. Repeat the procedure once and if necessary, continue to wet the wheels.
After this measurement test has been accomplished, measure the watermarks left by the tires using a tape measure, 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 opposite side of the circle. You could determine the inside turning radius by stretching the tape measure across the circle left by the interior tires. Next, 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 circle's diameter.
In order to establish the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the vehicle. After this is accomplished, the next step is to find the point on the pavement directly below. 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.
