The forklift's turning radius is also known as the turning circle, that is vital information for the driver to have. It gives the driver the knowledge of how much space is needed to turn the forklift around. Like for example, a tighter turning radius enables the machine to successfully function in tight places and crowded areas, thus improving the lift truck's maneuverability. Operators who are not aware of this measurement could cause damage to the machinery or to the property.
Before testing the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Begin the test with having the trained driver in the cab to control the equipment's functions. Another individual on the ground utilizes a spray bottle or a hose to wet the inside and outside of the unit's wheels. After that, drive the machine in a complete circle with the wheels turned to the maximum angle. Repeat the procedure once and continue if necessary to wet the wheels.
When this measurement test has been completed, measure the watermarks left by the tires with a tape measure, from the midpoint of the tire mark 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 circle's opposite side. The inside turning diameter could be established by stretching the tape measure across the circle left by the inner tires. Next, 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.
In order to establish the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the vehicle. After this is completed, the next step is to locate the point on the pavement directly below. This point to the turning center indicates the machine clearance radius. As a rule, wall-to-wall turning diameter is two times the machinery clearance radius.
