To make sure that safety is a main concern, there are 5 important steps. To be able to make certain that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Next assess if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the model is working in a safe manner. The 4th thing to take into account is Proper Operation, in order to determine whether or not the model is safely working. Last of all, Proper Shutdown must be checked so as to make sure the model is capable of shutting down properly and is in a safe place.
There is a machinery that 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 for sure there are risks.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The back axles usually oscillates, therefore the back wheels are not considered part of the base. The telehandler remains upright so long as the center of gravity of the machine, which is defined as the point in 3 dimensions around which the weight of the machinery is balanced, stays oriented in the stability triangle.
When a load is placed on the forks whilst the boom is down, the center of gravity down and forward. The load if raised will change the center of gravity upwards to the rear. At the same time, when this happens, 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 right or left. It is this wandering action that could change the stability triangle and leave less room for the frame to remain balanced if it is not completely level. Like for example, 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 a point on the boom and the center of the ground. If the frame is not level, the center of gravity would not be oriented over the centerline of the machine. The stability triangle is always aligned with the centerline of the telehandler.
