The lift truck's turning radius is also known as the turning circle, that is vital information for the operator to have. It gives the driver the information of how much space is required to turn the forklift around. For instance, a tighter turning radius enables the equipment to successfully operate in restricted places and congested areas, thus enhancing the forklift's maneuverability. Drivers who are not aware of this measurement could cause damage to the machinery or to the property.
Before checking the turning radius, check the steering geometry alignment and correct it if it requires adjustment. Begin the test with having the trained driver in the cab to control the machine's functions. Another individual on the ground utilizes a hose or a spray bottle to wet the inside and outside of the unit's wheels. Then, drive the machinery in a whole circle with the wheels turned to the maximum angle. Repeat the process once and continue if necessary to wet the wheels.
Measure the watermarks left by the tires utilizing a tape measure after your measurement test has been completed. The watermark test starts 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 outside tires from one side of the circle to the circle's opposite side. You could determine the inside turning radius by stretching the tape measure across the circle left by the inner tires. Next, 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 diameter of the circle.
Drop a plumb line from the extreme outside radial extension on the equipment in order to establish the wall-to-wall turning diameter. When this is done, next find the point on the pavement directly beneath. This point to the turning center indicates the vehicle clearance radius. As a rule, wall-to-wall turning diameter is twice the machinery clearance radius.
