To make certain that safety is a top priority, there are 5 key steps. To be able to make sure that the model is visually safe, the first step is to perform a Walk-Around Inspection. Next assess if the worksite is safe to use with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the model is working in a safe way. The 4th thing to take into account is Proper Operation, so as to determine whether or not the model is safely working. Last of all, Proper Shutdown must be checked so as to make sure the model 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 which stands on a triangular footprint and lifts heavy weights to impressive heights. The main objective is to be able to keep the telehandler upright, but surely there are dangers.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Normally the back axle oscillates and therefore, the back wheels are not a 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 weight of the equipment is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time moves the center of gravity down and forward. Lifting the load would change the center of gravity to the rear and upwards. At the same time, the stability triangle shrinks when this happens. Thus, the higher you raise a load, the less of a margin for error you have since the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move left or right. This wandering action can change the stability triangle, leaving 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 will always be able to 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 equipment's centerline. The stability triangle is continuously aligned with the centerline of the telehandler.
