The forklift's turning radius is also known as the turning circle, which is vital information for the operator to have. It gives the operator the knowledge of how much space is needed to turn the forklift around. Like for example, a tighter turning radius enables the machine to function successfully in crowded areas and tight places, therefore improving the lift truck's maneuverability. Operators who do not know this measurement may cause damage to the property or to the machinery.
Make the necessary steering geometry alignment corrections prior to testing the turning radius. The test must begin with an operator trainer assisting inside the cab where they could help 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. Then, 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.
Once this measurement test has been accomplished, measure the watermarks left by the tires utilizing a tape measure, from the tire mark's midpoint to a similar point across the circle's diameter. 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 inner tires. Then, 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 circle's diameter.
Drop a plumb line from the extreme outside radial extension on the machine in order to establish the wall-to-wall turning diameter. When this is accomplished, next 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 machinery clearance radius.
