To make sure that safety is a main concern, there are 5 important steps. To be able to make certain that the model is visually safe, the first step is to perform a Walk-Around Inspection. After that check if the work location is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the unit is safely working. The 4th thing to think about is Proper Operation, so as to determine whether or not the model is working safely. Last of all, Proper Shutdown must be checked so as to make sure the unit is in a safe place and is capable of shutting down properly.
At the center of the 5 steps and this regulation, there is a machine that stands on a triangular footprint and lifts heavy weights to impressive heights. The key goal is to be able to maintain the telehandler upright, but surely there are risks.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The rear axles often oscillates, therefore the back 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 weight of the machine is balanced, stays oriented inside the stability triangle.
When a load is placed on the forks whilst the boom is down, the center of gravity forward and down. The load if lifted will move the center of gravity to the rear upwards. At the same time, when this happens, the stability triangle shrinks. Thus, the higher you raise 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 left or right. 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 completely level. Like for example, 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 a point on the boom and the center of the ground. If the frame is not level, the center of gravity would not be oriented over the centerline of the equipment. The stability triangle is always aligned with the equipment's centerline.
