There are 5 important steps to ensuring safety is a main concern. The initial step is completing a Walk-Around Inspection in order to assure that the unit is visually safe. Next check if the work place is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to know whether or not the unit is functioning safely. The 4th thing to consider is Proper Operation, so as to determine whether or not the unit is safely operating. Last of all, Proper Shutdown needs to be checked so as to make certain the unit is in a safe place and is capable of shutting down correctly.
There is a machine 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 maintain the telehandler upright, but of course there are risks.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Typically the back axle oscillates and therefore, the rear wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the machinery, which is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time moves the center of gravity forward and down. Raising the load would change the center of gravity to the rear and upwards. At the same time, when this happens, the stability triangle shrinks. Hence, the higher you lift 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 right or left. 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 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 somewhere 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 centerline of the machine. The stability triangle is continuously aligned with the centerline of the machine.
