To make sure that safety is a main concern, there are 5 key steps. To be able to make certain that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Then check if the worksite is safe to use with a Worksite Assessment. The Function Test is the third step in order to know whether or not the model is functioning safely. The 4th thing to consider is Proper Operation, so as to know whether or not the unit is operating safely. Last of all, Proper Shutdown has to be checked in order 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 machine which lifts heavy weights to impressive heights and stands on a triangular footprint. The key objective is to keep the telehandler upright, but of course there are risks.
The rear-axle pivot point, and the two front wheels make up the telehandler's triangular base. Usually the back axle oscillates and therefore, the rear wheels are not a part of the base. The telehandler remains upright as long as the equipment's center of gravity, that is defined as the point in 3 dimensions around which the equipment's weight is balanced, stays oriented in the stability triangle.
When a load is positioned on the forks whilst the boom is down, the center of gravity forward and down. The load if raised will move the center of gravity upwards to the rear. At the same time, the stability triangle shrinks when this happens. Therefore, the higher you raise 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 completely level. 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 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 machinery. The stability triangle is continuously aligned with the telehandler's centerline.
