The lift truck's turning radius is also known as the turning circle, which is essential information for the driver to have. It gives the operator the information of how much space is needed to turn the forklift around. Like for instance, a tighter turning radius allows the machine to successfully work in restricted places and congested areas, thus enhancing the maneuverability of the lift truck. Drivers who do not know this measurement may cause damage to the property or to the machinery.
Make the necessary steering geometry alignment corrections before testing the turning radius. The test should start with an operator trainer assisting inside the cab where they can assist to control the machine's functions. Another individual on the ground utilizes a spray bottle or a hose to wet the inside and outside of the model's wheels. After that, drive the equipment in a complete circle with the wheels turned to the maximum angle. Repeat the process once and continue if necessary to wet the wheels.
After 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 outside tires from one side of the circle to the opposite side of the circle. You can determine the inside turning radius by stretching the tape measure across the circle left by the interior tires. After that, 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.
In order to determine the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the machinery. After this is completed, the next step is to locate the point on the pavement directly beneath. This point to the turning center indicates the machine clearance radius. As a rule, wall-to-wall turning diameter is twice the machine clearance radius.
