There are 5 key steps to making sure that safety is a main concern. The first step is completing a Walk-Around Inspection to be able to assure that the unit is visually safe. After that check if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the model is safely working. The 4th thing to think about is Proper Operation, in order to determine whether or not the unit is safely working. Lastly, Proper Shutdown must be checked in order 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 machine that stands on a triangular footprint and lifts heavy weights to impressive heights. The key objective is to be able to keep the telehandler upright, but surely there are dangers.
The telehandler's triangular base comprises the two front wheels and the rear-axle pivot point. The back axles normally oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright so long as the center of gravity of the equipment, that is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented in 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, the stability triangle shrinks when this happens. Therefore, the higher you lift a load, the less of a margin for error you have because the stability triangle lessens.
With a stable but small stability triangle, it leaves less room for the center of gravity to move right or left. This wandering action could change the stability triangle, leaving less room for the frame to remain balanced if it is not completely 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 equipment's centerline. The stability triangle is continuously aligned with the equipment's centerline.
