The turning radius on a forklift is also known as the turning circle. This information is vital for a machine operator to have. It gives the operator the knowledge of how much space is needed to turn the lift truck around. Like for instance, a tighter turning radius enables the machinery to successfully work in tight places and congested areas, therefore enhancing the lift truck's maneuverability. Drivers who do not know 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 in the cab where they can assist to control the machine's functions. Another individual on the ground uses a hose or a spray bottle to wet the inside and outside of the unit's wheels. Then, drive the machine in a complete circle with the wheels turned to the maximum angle. Repeat the procedure once and continue if necessary to wet the wheels.
After this measurement test has been done, measure the watermarks left by the tires with 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 one side of the circle to the circle's opposite side. You could establish the inside turning radius by stretching the tape measure across the circle left by the inner tires. After that, divide these numbers in 2 to be able to establish the turning radius. Be sure to note that the turning center is the midpoint of the diameter of the circle.
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 accomplished, the next step is to find the point on the pavement directly underneath. This point to the turning center indicates the equipment clearance radius. As a rule, wall-to-wall turning diameter is two times the vehicle clearance radius.
