The lift truck's turning radius is also known as the turning circle, that is vital information for the driver to have. It gives the driver the information of how much space is required to turn the lift truck around. For example, a tighter turning radius enables the machine to successfully function in congested areas and restricted places, therefore improving the forklift's maneuverability. Drivers who are not aware of this measurement can cause damage to the machinery or to the property.
Make the necessary steering geometry alignment corrections prior to checking the turning radius. The test must start with an operator trainer assisting in the cab where they can help to control the equipment's functions. Another individual on the ground utilizes a hose or a spray bottle to wet the outside and inside of the unit's wheels. Next, drive the machine in a complete circle with the wheels turned to the maximum angle. Repeat the process once and if necessary, continue to wet the wheels.
Measure the watermarks left by the tires with a tape measure after your measurement test has been completed. The watermark test starts 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 exterior tires from the circle's one side to the circle's opposite side. The inside turning diameter could be established by stretching the tape measure across the circle left by the inner 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.
Drop a plumb line from the extreme outside radial extension on the vehicle in order to establish the wall-to-wall turning diameter. When this is accomplished, next find the point on the pavement directly underneath. This point to the turning center indicates the clearance radius of the machinery. As a rule, wall-to-wall turning diameter is twice the machine clearance radius.
