There are 5 important steps to ensuring safety is a main concern. The first step is completing a Walk-Around Inspection in order to insure that the model is visually safe. After that check if the work place is safe to use with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is functioning safely. The 4th thing to take into consideration is Proper Operation, so as to know whether or not the model is working safely. Last of all, Proper Shutdown should be checked in order to make sure the unit is in a safe place and is capable of shutting down properly.
There is a machinery that lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The main objective is to be able to maintain 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 rear axle oscillates and hence, the rear wheels are not a part of the base. The telehandler remains upright so long as the equipment'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 placed on the forks while the boom is down, the center of gravity forward and down. The load if raised will change the center of gravity upwards to the rear. At the same time, the stability triangle shrinks when this occurs. 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 that could change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. Like for instance, 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 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 machine. The stability triangle is always aligned with the telehandler's centerline.
