The turning radius on a lift truck is also referred to as the turning circle. This information is important for a machine driver to have. It gives the driver the knowledge of how much space is needed to turn the forklift around. For instance, a tighter turning radius enables the machine to function successfully in tight places and congested areas, therefore enhancing the maneuverability of the forklift. Drivers who are not aware of this measurement can cause damage to the machine or to the property.
Make the necessary steering geometry alignment corrections prior to checking the turning radius. The test should begin with an operator trainer assisting inside the cab where they could help 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 unit's wheels. After that, drive the equipment 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 with a tape measure when your measurement test has been done. The watermark test begins from the tire mark's midpoint to a similar point across the circle's diameter. For the outside turning diameter, measure the watermark left by the outside tires from one side of the circle to the opposite side of the circle. You could determine 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.
Drop a plumb line from the extreme outside radial extension on the vehicle in order to determine the wall-to-wall turning diameter. Once this is completed, next locate the point on the pavement directly beneath. This point to the turning center indicates the machinery clearance radius. As a rule, wall-to-wall turning diameter is twice the equipment clearance radius.
