There are 5 key steps to making certain that safety is a top priority. The first step is completing a Walk-Around Inspection in order to assure that the model is visually safe. Next 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 in a safe way. The 4th thing to take into account is Proper Operation, in order to determine whether or not the unit is safely working. Lastly, Proper Shutdown must be checked so as to make certain the unit is capable of shutting down correctly and is in a safe place.
There is a machinery that lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The key objective is to keep 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. Normally the rear axle oscillates and therefore, the rear 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 machine's weight is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that same time moves the center of gravity down and forward. Lifting the load will change the center of gravity to the rear and upwards. At the same time, when this occurs, the stability triangle shrinks. Therefore, the higher you raise 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 can 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 will 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 will not be oriented over the centerline of the machinery. The stability triangle is continuously aligned with the centerline of the machine.
