The turning radius on a lift truck is also referred to as the turning circle. This information is essential for a machine driver to have. It gives the driver the knowledge of how much space is required to turn the lift truck around. Like for instance, a tighter turning radius enables the equipment to function successfully in restricted places and crowded areas, therefore enhancing the lift truck's maneuverability. Drivers who are not aware of this measurement could cause damage to the machine or to the property.
Make the necessary steering geometry alignment corrections prior to checking the turning radius. The test must begin with an operator trainer assisting inside the cab where they can assist to control the equipment'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 if necessary, continue to wet the wheels.
Once this measurement test has been accomplished, measure the watermarks left by the tires using a tape measure, from the midpoint of the tire mark to a similar point across the diameter of the circle. 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 establish the inside turning radius by stretching the tape measure across the circle left by the interior 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 diameter of the circle.
To be able to determine the wall-to-wall turning diameter, drop a plumb line from the extreme outside radial extension on the machinery. After this is completed, the next step is to locate the point on the pavement directly beneath. This point to the turning center indicates the machine clearance radius. As a rule, wall-to-wall turning diameter is two times the clearance radius of the machine.
