There are 5 important steps to ensuring safety is a main concern. The initial step is completing a Walk-Around Inspection in order to insure that the unit is visually safe. Then check if the worksite 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 working safely. The 4th thing to take into consideration is Proper Operation, so as to determine whether or not the model is safely working. Lastly, Proper Shutdown needs to be checked in order to make certain the unit is capable of shutting down correctly and is in a safe place.
There is a machine which lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The main goal is to keep the telehandler upright, but surely there are dangers.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The back axles often oscillates, hence the back wheels are not considered part of the base. The telehandler remains upright so long as the equipment's center of gravity, 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 placed on the forks whilst the boom is down, the center of gravity forward and down. The load if lifted would move the center of gravity to the rear upwards. 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 since 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. For example, imagine the center of gravity resembling a plumb bob hanging from the boom. You would always be able to 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 will not be oriented over the centerline of the equipment. The stability triangle is always aligned with the machine's centerline.
