To make sure that safety is a main concern, there are 5 important steps. In order to ensure that the model is visually safe, the initial step is to perform a Walk-Around Inspection. Then assess if the worksite is safe to utilize 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 think about is Proper Operation, in order to determine whether or not the unit is safely working. Lastly, Proper Shutdown must 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 which lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The main objective is to be able to keep the telehandler upright, but of course there are dangers.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Usually the rear axle oscillates and thus, the back wheels are not a part of the base. The telehandler remains upright so long as the machine's center of gravity, that is defined as the point in 3 dimensions around which the weight of the machine 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 lifted would change the center of gravity upwards to the rear. At the same time, when this occurs, the stability triangle shrinks. Thus, the higher you raise 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 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 would 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 would not be oriented over the machine's centerline. The stability triangle is always aligned with the centerline of the machine.
