The turning radius on a lift truck is also known as the turning circle. This information is important for a machinery operator to have. It gives the driver the knowledge of how much space is required to turn the forklift around. For example, a tighter turning radius enables the machine to operate successfully in congested areas and tight places, therefore enhancing the maneuverability of the forklift. Operators who do not know this measurement may cause damage to the equipment or to the property.
Make the necessary steering geometry alignment corrections before checking the turning radius. The test must start with an operator trainer assisting in 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 inside and outside of the unit's wheels. Next, 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.
When this measurement test has been accomplished, measure the watermarks left by the tires using a tape measure, 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 exterior 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 inner tires. Then, divide these numbers in 2 in order to determine 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 machine in order to determine the wall-to-wall turning diameter. Once this is accomplished, next locate the point on the pavement directly beneath. This point to the turning center indicates the clearance radius of the machinery. As a rule, wall-to-wall turning diameter is twice the equipment clearance radius.
