The forklift's turning radius is also referred to as the turning circle, that is essential information for the operator to have. It gives the operator the information of how much space is required to turn the forklift around. For instance, a tighter turning radius allows the machinery to successfully function in tight places and crowded areas, therefore enhancing the maneuverability of the forklift. Operators who do not know this measurement may cause damage to the machinery or to the property.
Make the necessary steering geometry alignment corrections before testing the turning radius. The test should start with an operator trainer helping in the cab where they could assist to control the equipment's functions. A second individual on the ground utilizes a hose or a spray bottle to wet the outside and inside of the model's wheels. After that, drive the machinery 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. The inside turning diameter can be established 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 sure to note that the turning center is the midpoint of the circle's diameter.
Drop a plumb line from the extreme outside radial extension on the machine in order to determine the wall-to-wall turning diameter. Once this is accomplished, next locate the point on the pavement directly underneath. This point to the turning center indicates the vehicle clearance radius. As a rule, wall-to-wall turning diameter is two times the machine clearance radius.
