To make certain that safety is a top priority, there are 5 key steps. In order to ensure that the unit is visually safe, the first step is to perform a Walk-Around Inspection. After that check if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the model is working safely. The 4th thing to consider is Proper Operation, in order to know whether or not the unit is operating safely. Last of all, Proper Shutdown should 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 maintain the telehandler upright, but for sure there are dangers.
The telehandler's triangular base consists of the two front wheels and the rear-axle pivot point. The rear axles often oscillates, hence the back wheels are not considered part of the base. The telehandler remains upright as long as the machine's center of gravity, that is defined as the point in 3 dimensions around which the equipment's weight 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. Lifting the load will move the center of gravity upwards and to the rear. At the same time, the stability triangle shrinks when this happens. 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 could 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 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 equipment's centerline. The stability triangle is always aligned with the centerline of the telehandler.
