To make sure that safety is a main concern, there are 5 key steps. To be able to ensure that the model is visually safe, the initial step is to perform a Walk-Around Inspection. Then check if the work location is safe to use with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is functioning in a safe manner. The 4th thing to consider is Proper Operation, so as to know whether or not the model is safely operating. 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.
There is a machinery 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 risks.
The triangular base of the telehandler comprises the rear-axle pivot point and the two front wheels. The rear axles often oscillates, therefore 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 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 changes the center of gravity down and forward. Raising the load will move the center of gravity to the rear and upwards. At the same time, when this happens, the stability triangle shrinks. 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 right or left. It is this wandering action that could change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. Like 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 telehandler.
