The turning radius on a lift truck is also known as the turning circle. This information is vital for a machinery operator to have. It gives the operator the information of how much space is required to turn the forklift around. For instance, a tighter turning radius allows the machinery to operate successfully in crowded areas and tight places, thus enhancing the lift truck's maneuverability. Operators who do not know 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 must begin with an operator trainer assisting inside the cab where they can assist to control the equipment'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 machine in a whole circle with the wheels turned to the maximum angle. Repeat the process once and if necessary, continue to wet the wheels.
When this measurement test has been completed, measure the watermarks left by the tires utilizing a tape measure, from the midpoint of the tire mark to a similar point across the circle's diameter. For the outside turning diameter, measure the watermark left by the outside tires from the circle's one side to the circle's opposite side. You could determine the inside turning radius by stretching the tape measure across the circle left by the inner tires. Next, 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 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 vehicle. 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 machine clearance radius. As a rule, wall-to-wall turning diameter is two times the clearance radius of the machine.
