To make certain that safety is a top priority, there are 5 important steps. In order to make sure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Next check 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 working safely. The 4th thing to consider is Proper Operation, in order to determine whether or not the model is operating safely. Lastly, Proper Shutdown must be checked so as 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 maintain the telehandler upright, but for sure there are risks.
The telehandler's triangular base consists of the two front wheels and the rear-axle pivot point. The rear axles often oscillates, thus the rear wheels are not considered part of the base. The telehandler remains upright as long as the center of gravity of the equipment, which is defined as the point in 3 dimensions around which the equipment's weight 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. Raising the load would change the center of gravity upwards and to the rear. At the same time, when this occurs, the stability triangle shrinks. Hence, the higher you lift a load, the less of a margin for error you have because the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move right or left. This wandering action could change the stability triangle, leaving less room for the frame to remain balanced if it is not perfectly level. Like for instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You can 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 would not be oriented over the centerline of the machine. The stability triangle is continuously aligned with the equipment's centerline.
