To ensure that safety is a top priority, there are 5 important steps. To be able to make sure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Then check if the work location is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the model is safely working. The 4th thing to take into account is Proper Operation, so as to know whether or not the unit is safely operating. Last of all, Proper Shutdown must be checked so as to make certain the unit 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 maintain the telehandler upright, but of course there are dangers.
The two front wheels, and the rear-axle pivot point make up the triangular base of the telehandler. Normally the rear axle oscillates and thus, the back wheels are not a part of the base. The telehandler remains upright so long as the center of gravity of the machinery, which is defined as the point in 3 dimensions around which the weight of the machine 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 forward and down. Lifting the load would change the center of gravity to the rear and upwards. At the same time, when this occurs, the stability triangle shrinks. Therefore, the higher you raise 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 left or right. This wandering action can 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 will always be able to 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 machine's centerline. The stability triangle is continuously aligned with the centerline of the equipment.
