To make certain that safety is a top priority, there are 5 important steps. To be able to make sure that the model is visually safe, the initial step is to perform a Walk-Around Inspection. 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 functioning safely. The 4th thing to consider is Proper Operation, in order to determine whether or not the unit is working safely. Lastly, Proper Shutdown must be checked so as to make certain the model is in a safe place and is capable of shutting down properly.
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 surely there are risks.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Normally the back axle oscillates and therefore, the rear wheels are not a 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 weight of the machine is balanced, stays oriented in the stability triangle.
When the boom is down, adding a load to the forks at that same time changes the center of gravity forward and down. Raising the load will move the center of gravity to the rear and upwards. 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 since the stability triangle lessens.
With a small but stable 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 example, imagine the center of gravity resembling a plumb bob hanging from the boom. You could always 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 would not be oriented over the centerline of the machine. The stability triangle is always aligned with the equipment's centerline.
