To make certain that safety is a top priority, there are 5 key steps. In order to ensure that the model is visually safe, the first step is to perform a Walk-Around Inspection. Then check if the worksite 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 manner. The 4th thing to think about is Proper Operation, so as to determine whether or not the model is working safely. Last of all, Proper Shutdown must be checked in order to make certain the unit 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 which stands on a triangular footprint and lifts heavy weights to impressive heights. The main objective is to be able to keep the telehandler upright, but for sure there are risks.
The triangular base of the telehandler consists of the rear-axle pivot point and the two front wheels. The rear axles normally oscillates, hence the back wheels are not considered part of the base. The telehandler remains upright so long as the equipment's center of gravity, which is defined as the point in 3 dimensions around which the equipment's weight is balanced, stays oriented inside the stability triangle.
When a load is positioned on the forks while the boom is down, the center of gravity down and forward. The load if raised would move the center of gravity to the rear upwards. At the same time, the stability triangle shrinks when this happens. Therefore, the higher you lift a load, the less of a margin for error you have since 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 which could change the stability triangle and leave 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 will not be oriented over the machine's centerline. The stability triangle is continuously aligned with the telehandler's centerline.
