There are 5 key steps to making certain that safety is a main concern. The initial step is completing a Walk-Around Inspection in order to assure that the unit is visually safe. After that check if the work location is safe to operate in 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 account is Proper Operation, in order to determine whether or not the unit is working safely. Last of all, Proper Shutdown should be checked so as to make certain the unit is capable of shutting down properly and is in a safe place.
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 main goal is to maintain the telehandler upright, but surely there are dangers.
The rear-axle pivot point, and the two front wheels make up the telehandler's triangular base. Normally the rear axle oscillates and hence, the back wheels are not a part of the base. The telehandler remains upright so long as the center of gravity of the machine, 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 a load is positioned on the forks whilst the boom is down, the center of gravity forward and down. The load if raised will move the center of gravity upwards to the rear. At the same time, when this occurs, the stability triangle shrinks. Hence, 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 can change the stability triangle and leave 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 can 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 continuously aligned with the centerline of the telehandler.
