There are 5 important steps to making sure that safety is a main concern. The initial step is completing a Walk-Around Inspection to be able to assure that the model is visually safe. After that check if the work location is safe to operate in with a Worksite Assessment. The Function Test is the third step so as to know whether or not the model is working in a safe manner. The 4th thing to think about is Proper Operation, in order to know whether or not the unit is safely working. Lastly, Proper Shutdown needs to be checked so as 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 that lifts heavy weights to impressive heights and stands on a triangular footprint. The key objective is to keep the telehandler upright, but for sure there are dangers.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The rear axles normally oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright so long as the machine's center of gravity, 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 same time moves the center of gravity forward and down. Raising the load will change the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. Therefore, the higher you lift a load, the less of a margin for error you have because 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 could change the stability triangle and leave less room for the frame to remain balanced if it is not completely level. For example, imagine the center of gravity resembling a plumb bob hanging from the boom. You would always be able to find the center of gravity somewhere 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 equipment's centerline. The stability triangle is continuously aligned with the centerline of the machine.
