To make certain that safety is a main concern, there are 5 important steps. In order to make sure that the unit is visually safe, the initial 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 in order to determine whether or not the unit is safely functioning. The 4th thing to take into consideration is Proper Operation, so as to determine whether or not the unit is working safely. Last of all, Proper Shutdown should be checked in order to make certain the model is capable of shutting down correctly and is in a safe place.
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 key 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 back axle oscillates and therefore, the back wheels are not a part of the base. The telehandler remains upright so long as the machine's center of gravity, which 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 changes the center of gravity down and forward. Raising the load will change the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. Therefore, the higher you lift a load, the less of a margin for error you have because 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 could change the stability triangle, leaving less room for the frame to remain balanced if it is not perfectly level. Like for example, 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 would not be oriented over the centerline of the machine. The stability triangle is continuously aligned with the centerline of the machine.
