There are 5 important steps to ensuring safety is a top priority. The first step is completing a Walk-Around Inspection to be able to insure that the unit is visually safe. Then check if the work place is safe to use with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is safely functioning. The 4th thing to take into account is Proper Operation, so as to know whether or not the model is safely operating. Last of all, Proper Shutdown should be checked so as to make sure the unit is in a safe place and is capable of shutting down properly.
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 goal is to keep the telehandler upright, but of course there are risks.
The rear-axle pivot point, and the two front wheels make up the telehandler's triangular base. Typically the rear 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 machine, which is defined as the point in 3 dimensions around which the equipment's weight is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time changes the center of gravity forward and down. Lifting the load would move the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. 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 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. Like for instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You will always be able to 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 centerline of the equipment. The stability triangle is continuously aligned with the equipment's centerline.
