To make sure that safety is a main concern, there are 5 key steps. To be able to ensure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Next check if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is working in a safe manner. The 4th thing to consider is Proper Operation, in order to determine whether or not the unit is safely working. Last of all, Proper Shutdown needs to be checked in order to make sure the model is capable of shutting down correctly and is in a safe place.
There is a machine that 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 surely there are dangers.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Typically the back axle oscillates and therefore, the back wheels are not a part of the base. The telehandler remains upright so long as the equipment's center of gravity, that is defined as the point in 3 dimensions around which the weight of the machinery is balanced, stays oriented in the stability triangle.
When a load is placed on the forks while the boom is down, the center of gravity down and forward. The load if raised would move the center of gravity to the rear 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 because 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 could change the stability triangle and leave 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 could always find the center of gravity somewhere 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 always aligned with the equipment's centerline.
