The forklift's turning radius is also known as the turning circle, that is vital information for the driver to have. It gives the operator the knowledge of how much space is needed to turn the forklift around. For example, a tighter turning radius allows the equipment to successfully operate in restricted places and congested areas, therefore enhancing the maneuverability of the lift truck. Operators who do not know this measurement could cause damage to the machinery 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 helping inside the cab where they could help to control the machine's functions. Another person on the ground utilizes a spray bottle or a hose 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.
Once this measurement test has been completed, measure the watermarks left by the tires utilizing 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 the circle's one side to the circle's opposite side. The inside turning diameter could be determined by stretching the tape measure across the circle left by the inner tires. Then, divide these numbers in 2 in order to establish the turning radius. Be sure to note that the turning center is the midpoint of the circle's diameter.
To be able to establish the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the machinery. After this is done, the next step is to 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 clearance radius of the machinery.
