To ensure that safety is a main concern, 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. After that check if the work place is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is functioning in a safe way. The 4th thing to think about is Proper Operation, so as to know whether or not the model is safely operating. Lastly, Proper Shutdown must 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 machinery that lifts heavy weights to impressive heights and stands on a triangular footprint. The key objective is to be able to maintain the telehandler upright, but of course there are risks.
The two front wheels, and the rear-axle pivot point make up the triangular base of the telehandler. Usually 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 equipment is balanced, stays oriented in the stability triangle.
When the boom is down, adding a load to the forks at that time moves the center of gravity forward and down. Lifting the load will move the center of gravity upwards and to the rear. At the same time, when this occurs, the stability triangle shrinks. Hence, the higher you lift a load, the less of a margin for error you have because the stability triangle lessens.
With a stable but small stability triangle, it leaves less room for the center of gravity to move left or right. 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 someplace 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 will not be oriented over the centerline of the machine. The stability triangle is always aligned with the machine's centerline.
