To make certain that safety is a main concern, there are 5 key steps. To be able to make certain that the model is visually safe, the initial 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 know whether or not the model is safely functioning. The 4th thing to take into account is Proper Operation, so as to know whether or not the model is operating safely. Last of all, Proper Shutdown should be checked so as to make certain the unit is in a safe place and is capable of shutting down correctly.
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 main objective is to be able to maintain the telehandler upright, but for sure there are dangers.
The telehandler's triangular base comprises the rear-axle pivot point and the two front wheels. The rear axles normally oscillates, thus the rear wheels are not considered part of the base. The telehandler remains upright so long as the center of gravity of the machine, that is defined as the point in 3 dimensions around which the machine's weight is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time changes the center of gravity down and forward. Lifting the load would change the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this happens. Therefore, the higher you raise a load, the less of a margin for error you have as 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 completely 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 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 will not be oriented over the centerline of the machinery. The stability triangle is continuously aligned with the telehandler's centerline.
