To make certain that safety is a top priority, there are 5 key steps. In order to make certain that the unit is visually safe, the first step is to perform a Walk-Around Inspection. After that assess if the work place 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 take into consideration is Proper Operation, so as to know whether or not the model is operating safely. Last of all, Proper Shutdown has to be checked so as to make certain the model is capable of shutting down properly and is in a safe place.
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 main goal is to be able to keep the telehandler upright, but surely there are dangers.
The telehandler's triangular base comprises the rear-axle pivot point and the two front wheels. The back axles normally oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright so long as the machine's center of gravity, which is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time changes the center of gravity down and forward. Lifting the load will move the center of gravity to the rear and upwards. At the same time, when this happens, the stability triangle shrinks. Therefore, the higher you raise a load, the less of a margin for error you have as 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 perfectly level. For instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You could always 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 would not be oriented over the equipment's centerline. The stability triangle is continuously aligned with the machine's centerline.
