There are 5 key steps to ensuring safety is a top priority. The first step is completing a Walk-Around Inspection in order to insure that the model is visually safe. Then assess if the work location is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the model is working safely. The 4th thing to think about is Proper Operation, so as to know whether or not the unit is operating safely. Last of all, Proper Shutdown must be checked in order to make sure the unit is in a safe place and is capable of shutting down properly.
There is a machine that lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The key goal is to maintain the telehandler upright, but surely there are dangers.
The telehandler's triangular base comprises the two front wheels and the rear-axle pivot point. The back axles often oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright as long as the machine's center of gravity, which 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 forward and down. Lifting the load would move the center of gravity upwards and to the rear. At the same time, when this occurs, the stability triangle shrinks. Thus, the higher you raise 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 right or left. 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 completely level. Like 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 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 equipment's centerline.
