There are 5 important steps to making certain that safety is a top priority. The initial step is completing a Walk-Around Inspection to be able to insure that the model is visually safe. Next assess if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is functioning in a safe way. The 4th thing to think about is Proper Operation, so as to know whether or not the unit is safely operating. Last of all, Proper Shutdown has to be checked so as to make sure the unit 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 that stands on a triangular footprint and lifts heavy weights to impressive heights. The key objective is to maintain the telehandler upright, but of course there are risks.
The telehandler's triangular base comprises the rear-axle pivot point and the two front wheels. The rear axles normally oscillates, therefore the back wheels are not considered part of the base. The telehandler remains upright as 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 in the stability triangle.
When a load is positioned on the forks while the boom is down, the center of gravity down and forward. The load if raised would move the center of gravity upwards 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 left or right. This wandering action could change the stability triangle, leaving less room for the frame to remain balanced if it is not completely level. Like 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 would not be oriented over the machine's centerline. The stability triangle is always aligned with the telehandler's centerline.
