There are 5 important steps to making certain that safety is a top priority. The initial step is completing a Walk-Around Inspection in order to insure that the unit is visually safe. Then check if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to know 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 unit is operating safely. Last of all, Proper Shutdown must be checked in order to make certain 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 which lifts heavy weights to impressive heights and stands on a triangular footprint. The key objective is to maintain the telehandler upright, but surely there are risks.
The triangular base of the telehandler consists of the rear-axle pivot point and the two front wheels. The back axles often 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, which is defined as the point in 3 dimensions around which the weight of the machinery is balanced, stays oriented inside the stability triangle.
When a load is positioned on the forks whilst the boom is down, the center of gravity down and forward. The load if lifted would move the center of gravity upwards to the rear. At the same time, when this occurs, the stability triangle shrinks. Hence, the higher you lift a load, the less of a margin for error you have since the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move right or left. It is this wandering action which can change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. Like for example, 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 a point on the boom and the center of the ground. If the frame is not level, the center of gravity will not be oriented over the machine's centerline. The stability triangle is continuously aligned with the centerline of the telehandler.
