There are 5 key steps to ensuring safety is a top priority. The first step is completing a Walk-Around Inspection to be able to insure that the model is visually safe. Then assess if the work place is safe to use with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the model is functioning in a safe way. The 4th thing to consider is Proper Operation, so as to determine whether or not the model is working safely. Lastly, Proper Shutdown has to be checked in order to make certain the model is capable of shutting down correctly and is in a safe place.
At the center of the 5 steps and this regulation, there is a machinery which stands on a triangular footprint and lifts heavy weights to impressive heights. The main goal is to maintain the telehandler upright, but surely there are dangers.
The telehandler's triangular base consists of the two front wheels and the rear-axle pivot point. The back axles usually oscillates, therefore the back wheels are not considered part of the base. The telehandler remains upright as long as the equipment'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, the stability triangle shrinks when this happens. Thus, the higher you raise a load, the less of a margin for error you have because the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move right or left. This wandering action could change the stability triangle, leaving less room for the frame to remain balanced if it is not perfectly 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 a point on the boom and the center of the ground. If the frame is not level, the center of gravity would not be oriented over the machine's centerline. The stability triangle is continuously aligned with the centerline of the machine.
