The turning radius on a lift truck is also known as the turning circle. This piece of information is essential for a machine driver to have. It gives the driver the information of how much space is needed to turn the lift truck around. For instance, a tighter turning radius allows the equipment to function successfully in restricted places and congested areas, thus enhancing the maneuverability of the lift truck. Operators who are not aware of this measurement may 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 operator in the cab to control the equipment's functions. Another individual on the ground utilizes a hose or a spray bottle to wet the outside and inside of the model's wheels. After that, drive the machinery in a complete circle with the wheels turned to the maximum angle. Repeat the procedure once and continue if necessary to wet the wheels.
Measure the watermarks left by the tires using a tape measure when your measurement test has been done. The watermark test begins 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 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 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 circle's diameter.
Drop a plumb line from the extreme outside radial extension on the equipment in order to determine the wall-to-wall turning diameter. Once this is done, next locate the point on the pavement directly below. This point to the turning center indicates the clearance radius of the equipment. As a rule, wall-to-wall turning diameter is two times the machine clearance radius.
