The turning radius on a lift truck is also referred to as the turning circle. This piece of information is essential for a machine operator to have. It gives the driver the knowledge of how much space is needed to turn the lift truck around. For example, a tighter turning radius allows the machinery to successfully operate in crowded areas and restricted places, therefore improving the forklift's maneuverability. Operators who are not aware of this measurement could cause damage to the property or to the machine.
Make the necessary steering geometry alignment corrections before checking the turning radius. The test should start with an operator trainer assisting inside the cab where they can help to control the equipment's functions. A second person on the ground uses a hose or a spray bottle to wet the outside and inside of the unit's wheels. After that, drive the machine 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 utilizing a tape measure after your measurement test has been done. 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 exterior tires from one side of the circle to the opposite side of the circle. The inside turning diameter can be established by stretching the tape measure across the circle left by the interior tires. Next, divide these numbers in 2 to be able to establish the turning radius. Be sure 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 machine. After this is accomplished, the next step is to locate the point on the pavement directly underneath. This point to the turning center indicates the machine clearance radius. As a rule, wall-to-wall turning diameter is two times the clearance radius of the machinery.
