There are 5 important steps to making certain that safety is a main concern. The initial step is completing a Walk-Around Inspection to be able to insure that the unit is visually safe. Next assess if the worksite is safe to use with a Worksite Assessment. The Function Test is the third step in order to know whether or not the model is safely functioning. The 4th thing to consider is Proper Operation, so as to determine whether or not the unit is safely operating. Lastly, Proper Shutdown must be checked in order to make certain the model is in a safe place and is capable of shutting down properly.
At the center of the 5 steps and this regulation, there is a machine that stands on a triangular footprint and lifts heavy weights to impressive heights. The main objective is to be able to keep the telehandler upright, but surely there are risks.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Typically the back axle oscillates and thus, the back wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the machinery, that is defined as the point in 3 dimensions around which the weight of the equipment is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that same time changes the center of gravity down and forward. Lifting the load would change the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. Thus, the higher you lift a load, the less of a margin for error you have since 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 could change the stability triangle, leaving less room for the frame to remain balanced if it is not completely level. Like for example, imagine the center of gravity resembling a plumb bob hanging from the boom. You can always find the center of gravity somewhere 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 centerline of the equipment. The stability triangle is continuously aligned with the telehandler's centerline.
