To make certain that safety is a top priority, there are 5 key steps. To be able to ensure that the unit is visually safe, the first step is to perform a Walk-Around Inspection. Then check if the worksite 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 safely. The 4th thing to consider is Proper Operation, in order to know whether or not the model is working safely. Last of all, Proper Shutdown should be checked so as to make sure the model is in a safe place and is capable of shutting down properly.
There is a machine that lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The key goal is to be able to keep the telehandler upright, but for sure there are dangers.
The telehandler's triangular base comprises the two front wheels and the rear-axle pivot point. The back axles usually oscillates, thus the back wheels are not considered part of the base. The telehandler remains upright so long as the center of gravity of the machinery, that 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 down and forward. Lifting the load will change the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. Thus, 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 left or right. It is this wandering action that can change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. For instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You could always 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 machine's centerline. The stability triangle is continuously aligned with the telehandler's centerline.
