To ensure that safety is a main concern, there are 5 important steps. To be able to make certain that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Then assess if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is working safely. The 4th thing to take into account is Proper Operation, so as to determine whether or not the unit is working safely. Lastly, Proper Shutdown needs to 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 which stands on a triangular footprint and lifts heavy weights to impressive heights. The key goal is to keep the telehandler upright, but of course there are dangers.
The telehandler's triangular base comprises the rear-axle pivot point and the two front wheels. The back axles often oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright as long as the center of gravity of the machine, 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 down and forward. Lifting the load will change the center of gravity to the rear and upwards. 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 since the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move left or right. It is this wandering action which could 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 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 would not be oriented over the machine's centerline. The stability triangle is continuously aligned with the centerline of the machine.
