To make certain that safety is a main concern, there are 5 important steps. To be able to make certain that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. After that check 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 think about is Proper Operation, in order to determine whether or not the model is safely operating. Last of all, Proper Shutdown needs to be checked so as to make certain the unit is in a safe place and is capable of shutting down properly.
There is a machine which lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The main goal is to be able to keep the telehandler upright, but for sure there are dangers.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Normally the rear axle oscillates and hence, the back wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the equipment, that is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented inside 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 will change 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 as the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move right or left. This wandering action can change the stability triangle, leaving less room for the frame to remain balanced if it is not completely level. Like for instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You can always 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 centerline of the machine. The stability triangle is always aligned with the equipment's centerline.
