To make certain that safety is a top priority, there are 5 key steps. In order to ensure that the model is visually safe, the first step is to perform a Walk-Around Inspection. Next assess if the work place is safe to use with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is working in a safe way. The 4th thing to think about is Proper Operation, in order to know whether or not the unit is operating safely. Last of all, Proper Shutdown should be checked in order to make sure the unit 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 main goal is to be able to keep the telehandler upright, but of course there are risks.
The two front wheels, and the rear-axle pivot point make up the triangular base of the telehandler. Typically the back axle oscillates and thus, the rear wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the equipment, which is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented in the stability triangle.
When a load is positioned on the forks whilst the boom is down, the center of gravity forward and down. The load if lifted will move the center of gravity upwards to the rear. 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 because 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 can change the stability triangle and leave 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 someplace 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 machine's centerline.
