To make certain that safety is a main concern, there are 5 key steps. To be able to ensure that the unit is visually safe, the first step is to perform a Walk-Around Inspection. Then check 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 functioning in a safe way. The 4th thing to consider is Proper Operation, in order to know whether or not the model is working safely. Last of all, Proper Shutdown should be checked in order to make sure the model is capable of shutting down properly and is in a safe place.
There is a machine which lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The key objective is to be able to maintain the telehandler upright, but surely there are dangers.
The telehandler's triangular base consists of the two front wheels and the rear-axle pivot point. The back axles usually oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright so long as the machine's center of gravity, which is defined as the point in 3 dimensions around which the machine's weight is balanced, stays oriented in the stability triangle.
When a load is positioned on the forks while the boom is down, the center of gravity forward and down. The load if lifted will move the center of gravity to the rear 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 because 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 instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You could always find the center of gravity someplace 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 will not be oriented over the machine's centerline. The stability triangle is continuously aligned with the equipment's centerline.
