The turning radius on a forklift is also referred to as the turning circle. This piece of information is vital for a machinery driver to have. It gives the driver the knowledge of how much space is needed to turn the forklift around. For example, a tighter turning radius allows the machinery to successfully function in congested areas and tight places, therefore enhancing the maneuverability of the forklift. Operators who are not aware of this measurement can cause damage to the machine or to the property.
Make the necessary steering geometry alignment corrections prior to testing the turning radius. The test must begin with an operator trainer helping in the cab where they can help 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 unit'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.
Once this measurement test has been accomplished, measure the watermarks left by the tires using a tape measure, 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 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. 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.
To be able to determine the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the vehicle. After this is done, the next step is to locate the point on the pavement directly below. This point to the turning center indicates the machinery clearance radius. As a rule, wall-to-wall turning diameter is two times the equipment clearance radius.
