The turning radius on a forklift is also referred to 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 allows the machinery to successfully operate in tight places and congested areas, therefore enhancing the maneuverability of the forklift. Drivers who do not know this measurement could cause damage to the machine or to the property.
Before checking the turning radius, check the steering geometry alignment and correct it if it needs adjustment. Begin the test with having the trained operator inside the cab to control the equipment's functions. A second person on the ground uses a spray bottle or a hose to wet the outside and inside of the unit's wheels. After that, drive the machinery in a complete 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 accomplished, measure the watermarks left by the tires using a tape measure, from the tire mark's midpoint to a similar point across the diameter of the circle. 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. After that, 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 machine. 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 vehicle clearance radius. As a rule, wall-to-wall turning diameter is twice the equipment clearance radius.
