The turning radius on a lift truck is also known as the turning circle. This piece of information is important for a machine operator to have. It gives the operator the information of how much space is needed to turn the forklift around. Like for example, a tighter turning radius enables the equipment to operate successfully in restricted places and congested areas, thus enhancing the forklift's maneuverability. Drivers who are not aware of this measurement can cause damage to the equipment or to the property.
Prior to checking the turning radius, check the steering geometry alignment and correct it if it requires adjustment. Start the test with having the trained operator in the cab to control the machine's functions. Another individual on the ground utilizes a spray bottle or a hose to wet the outside and inside of the unit's wheels. After that, drive the machinery 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 done, 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 one side of the circle to the circle's opposite side. You can establish the inside turning radius by stretching the tape measure across the circle left by the interior tires. After that, 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 determine the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the machinery. After this is done, the next step is to find the point on the pavement directly underneath. This point to the turning center indicates the machine clearance radius. As a rule, wall-to-wall turning diameter is two times the clearance radius of the machinery.
