There are 5 key steps to making certain that safety is a top priority. The first step is completing a Walk-Around Inspection in order to assure that the model is visually safe. Then assess if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step in order to know whether or not the model is safely functioning. The 4th thing to consider is Proper Operation, so as to determine whether or not the model is safely operating. Lastly, Proper Shutdown must be checked so as to make certain the unit is capable of shutting down properly and is in a safe place.
At the center of the 5 steps and this regulation, there is a machine which stands on a triangular footprint and lifts heavy weights to impressive heights. The key goal is to be able to keep the telehandler upright, but of course there are dangers.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Normally the rear axle oscillates and thus, the rear wheels are not a part of the base. The telehandler remains upright so long as the machine's center of gravity, that is defined as the point in 3 dimensions around which the machine's weight is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time moves the center of gravity forward and down. Lifting the load will move the center of gravity upwards and to the rear. At the same time, when this occurs, the stability triangle shrinks. Thus, the higher you lift a load, the less of a margin for error you have since the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move left or right. This wandering action can change the stability triangle, leaving less room for the frame to remain balanced if it is not completely level. For example, imagine the center of gravity resembling a plumb bob hanging from the boom. You could always find the center of gravity someplace on a totally vertical line between the center of the ground and a point on the boom. If the frame is not level, the center of gravity will not be oriented over the equipment's centerline. The stability triangle is continuously aligned with the telehandler's centerline.
