The lift truck's turning radius is also known as the turning circle, which is essential information for the operator to have. It gives the driver the information of how much space is needed to turn the forklift around. Like for instance, a tighter turning radius enables the machinery to operate successfully in restricted places and congested areas, therefore enhancing the maneuverability of the forklift. Operators who are not aware of this measurement could cause damage to the property or to the equipment.
Prior to testing the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Start the test with having the trained driver inside the cab to control the equipment's functions. A second individual on the ground uses a spray bottle or a hose to wet the outside and inside of the model's wheels. Then, drive the machine in a complete circle with the wheels turned to the maximum angle. Repeat the procedure once and if necessary, continue to wet the wheels.
After this measurement test has been completed, measure the watermarks left by the tires utilizing a tape measure, 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 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 inner tires. Then, divide these numbers in 2 in order to establish the turning radius. Be certain to note that the turning center is the midpoint of the circle's diameter.
To be able to establish the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the equipment. After this is accomplished, the next step is to locate the point on the pavement directly below. This point to the turning center indicates the clearance radius of the vehicle. As a rule, wall-to-wall turning diameter is two times the clearance radius of the machinery.
