To make sure that safety is a top priority, there are 5 key steps. In order to ensure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Then check if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to know whether or not the model is safely working. The 4th thing to consider is Proper Operation, in order to know whether or not the model is operating safely. Last of all, Proper Shutdown should be checked in order to make certain the model is in a safe place and is capable of shutting down properly.
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 main goal is to keep the telehandler upright, but for sure there are risks.
The triangular base of the telehandler consists of the two front wheels and the rear-axle pivot point. The rear 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 machinery, that is defined as the point in 3 dimensions around which the weight of the machinery 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 to the rear and upwards. At the same time, the stability triangle shrinks when this happens. 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 perfectly level. For example, 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 the center of the ground and a point on the boom. If the frame is not level, the center of gravity would not be oriented over the centerline of the equipment. The stability triangle is always aligned with the centerline of the telehandler.
