To make sure that safety is a main concern, there are 5 important steps. To be able to make sure that the model is visually safe, the first step is to perform a Walk-Around Inspection. After that assess if the work place 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 safely working. The 4th thing to take into consideration is Proper Operation, in order to determine 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.
At the center of the 5 steps and this regulation, there is a machinery which lifts heavy weights to impressive heights and stands on a triangular footprint. The key goal is to be able to keep the telehandler upright, but surely 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 therefore, the back wheels are not a part of the base. The telehandler remains upright as long as the machine's center of gravity, which is defined as the point in 3 dimensions around which the equipment'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 lifted would move the center of gravity upwards to the rear. At the same time, the stability triangle shrinks when this occurs. Therefore, the higher you raise a load, the less of a margin for error you have as the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move right or left. 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 perfectly level. Like 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 will not be oriented over the machine's centerline. The stability triangle is always aligned with the centerline of the telehandler.
