There are 5 key steps to ensuring safety is a main concern. The initial step is completing a Walk-Around Inspection to be able to assure that the model is visually safe. After that assess if the work location is safe to use with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the unit is functioning safely. The 4th thing to take into consideration is Proper Operation, in order to know whether or not the unit is working safely. Last of all, Proper Shutdown must be checked so as to make sure the model is in a safe place and is capable of shutting down correctly.
There is a machinery which lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The key goal is to keep the telehandler upright, but of course there are risks.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The rear axles often oscillates, hence the back wheels are not considered 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 machine's weight is balanced, stays oriented inside the stability triangle.
When a load is positioned on the forks while the boom is down, the center of gravity down and forward. The load if raised would move the center of gravity upwards to the rear. At the same time, the stability triangle shrinks when this happens. Thus, the higher you raise a load, the less of a margin for error you have because the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move left or right. This wandering action could change the stability triangle, leaving 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 will always be able to 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 equipment's centerline. The stability triangle is always aligned with the centerline of the equipment.
