To ensure that safety is a top priority, there are 5 key steps. To be able to make certain that the unit is visually safe, the first step is to perform a Walk-Around Inspection. Then check if the worksite is safe to use 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 manner. The 4th thing to consider is Proper Operation, so as to know whether or not the unit is working safely. Last of all, Proper Shutdown needs to be checked in order to make certain 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 goal is to maintain the telehandler upright, but of course there are risks.
The triangular base of the telehandler comprises the two front wheels and the rear-axle pivot point. The back axles normally oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright so long as the center of gravity of the machine, which is defined as the point in 3 dimensions around which the weight of the machinery is balanced, stays oriented in 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. Raising the load will change the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. Therefore, the higher you raise 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 can change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. Like for example, 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 will not be oriented over the centerline of the machine. The stability triangle is always aligned with the centerline of the machine.
