There are 5 important steps to making sure that safety is a top priority. The initial step is completing a Walk-Around Inspection to be able to assure that the model is visually safe. Next check if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is safely functioning. The 4th thing to consider is Proper Operation, in order to know whether or not the unit 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 machinery that lifts heavy weights to impressive heights and stands on a triangular footprint. The main objective is to be able to maintain the telehandler upright, but for sure there are dangers.
The two front wheels, and the rear-axle pivot point make up the triangular base of the telehandler. Normally the back axle oscillates and therefore, the rear wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the machinery, that is defined as the point in 3 dimensions around which the machine's weight is balanced, stays oriented inside the stability triangle.
When a load is positioned on the forks while the boom is down, the center of gravity forward and down. The load if lifted will change the center of gravity to the rear upwards. At the same time, the stability triangle shrinks when this happens. Hence, 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 perfectly level. For instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You can 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 machine's centerline. The stability triangle is always aligned with the machine's centerline.
