There are 5 key steps to ensuring safety is a main concern. The initial step is completing a Walk-Around Inspection to be able to insure that the model 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 know whether or not the model is safely working. The 4th thing to think about is Proper Operation, in order to know whether or not the unit is safely working. Last of all, Proper Shutdown must be checked in order to make certain the unit is capable of shutting down correctly and is in a safe place.
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 be able to keep the telehandler upright, but of course there are dangers.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Usually the rear axle oscillates and therefore, the rear wheels are not a 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 weight of the machinery is balanced, stays oriented in the stability triangle.
When a load is placed on the forks while the boom is down, the center of gravity forward and down. The load if raised will change the center of gravity upwards to the rear. At the same time, when this occurs, the stability triangle shrinks. Hence, the higher you raise a load, the less of a margin for error you have as the stability triangle lessens.
With a stable but small stability triangle, it leaves less room for the center of gravity to move right or left. This wandering action can change the stability triangle, leaving 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 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 machine's centerline. The stability triangle is continuously aligned with the telehandler's centerline.
