The turning radius on a lift truck is also known as the turning circle. This information is vital for a machine operator to have. It gives the operator the information of how much space is required to turn the lift truck around. Like for instance, a tighter turning radius enables the equipment to successfully operate in crowded areas and restricted places, thus enhancing the maneuverability of the forklift. Drivers who are not aware of this measurement could cause damage to the machine or to the property.
Before testing the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Start the test with having the trained operator inside the cab to control the machine's functions. Another individual on the ground utilizes a hose or a spray bottle to wet the inside and outside of the model's wheels. Next, drive the machine in a whole circle with the wheels turned to the maximum angle. Repeat the process once and continue if necessary to wet the wheels.
After this measurement test has been done, 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 outside tires from the circle's one side to the circle's opposite side. You can determine the inside turning radius by stretching the tape measure across the circle left by the inner tires. Then, divide these numbers in 2 to be able to determine the turning radius. Be sure to note that the turning center is the midpoint of the diameter of the circle.
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 underneath. This point to the turning center indicates the machinery clearance radius. As a rule, wall-to-wall turning diameter is two times the clearance radius of the equipment.
