The turning radius on a forklift is also referred to as the turning circle. This piece of information is vital for a machine operator to have. It gives the driver the knowledge of how much space is needed to turn the lift truck around. Like for example, a tighter turning radius allows the machinery to successfully function in congested areas and tight places, thus improving the maneuverability of the lift truck. Drivers who are not aware of this measurement could cause damage to the property or to the machinery.
Make the necessary steering geometry alignment corrections before testing the turning radius. The test should begin with an operator trainer helping in the cab where they can help to control the machine's functions. Another individual on the ground uses a hose or a spray bottle to wet the inside and outside of the model's wheels. Then, drive the equipment in a complete circle with the wheels turned to the maximum angle. Repeat the procedure once and continue if necessary to wet the wheels.
When this measurement test has been done, measure the watermarks left by the tires with 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 outside tires from one side of the circle to the opposite side of the circle. The inside turning diameter could be established by stretching the tape measure across the circle left by the inner tires. Next, divide these numbers in 2 to be able to determine 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 vehicle. After this is completed, the next step is to find the point on the pavement directly underneath. This point to the turning center indicates the clearance radius of the machine. As a rule, wall-to-wall turning diameter is twice the machinery clearance radius.
