There are 5 important steps to ensuring safety is a top priority. The first step is completing a Walk-Around Inspection in order to insure that the unit is visually safe. Next assess if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to know whether or not the model is working safely. The 4th thing to take into account is Proper Operation, so as to know whether or not the unit is safely working. Lastly, Proper Shutdown has to be checked so as to make certain the model 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 machinery which lifts heavy weights to impressive heights and stands on a triangular footprint. The main goal is to maintain the telehandler upright, but for sure there are risks.
The rear-axle pivot point, and the two front wheels make up the telehandler's triangular base. Normally the rear axle oscillates and therefore, the rear wheels are not a part of the base. The telehandler remains upright so 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. Raising the load would move the center of gravity to the rear and upwards. 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 as the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move left or right. 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 completely level. Like for instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You will always be able to find the center of gravity someplace 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 centerline of the machine.
