There are 5 key steps to making certain that safety is a main concern. The initial step is completing a Walk-Around Inspection in order to insure that the unit is visually safe. Then assess if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the model is functioning in a safe way. The 4th thing to consider is Proper Operation, in order to determine whether or not the unit is safely working. Last of all, Proper Shutdown must be checked so as to make certain the unit 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 machine that stands on a triangular footprint and lifts heavy weights to impressive heights. The main 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 telehandler's triangular base. Usually the rear axle oscillates and thus, the rear wheels are not a part of the base. The telehandler remains upright so long as the center of gravity of the machinery, 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 would change the center of gravity upwards to the rear. At the same time, when this occurs, the stability triangle shrinks. Thus, the higher you lift a load, the less of a margin for error you have because the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move left or right. It is this wandering action that can change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. 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 will not be oriented over the centerline of the machine. The stability triangle is continuously aligned with the centerline of the telehandler.
