To make sure that safety is a main concern, there are 5 key steps. In order to ensure that the model is visually safe, the first step is to perform a Walk-Around Inspection. Next check if the worksite is safe to use with a Worksite Assessment. The Function Test is the third step so as to know whether or not the model is safely working. The 4th thing to think about is Proper Operation, so as to know whether or not the unit is operating safely. Last of all, Proper Shutdown should be checked in order to make sure the model is capable of shutting down correctly and is in a safe place.
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 keep the telehandler upright, but surely there are risks.
The two front wheels, and the rear-axle pivot point make up the triangular base of the telehandler. Normally the rear axle oscillates and hence, the rear wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the machinery, which is defined as the point in 3 dimensions around which the weight of the machinery 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. Lifting the load would move the center of gravity to the rear and upwards. 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 which can 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 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 machine. The stability triangle is continuously aligned with the centerline of the machine.
