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 operate in with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is working in a safe manner. The 4th thing to take into account is Proper Operation, so as to know whether or not the unit is operating safely. Lastly, Proper Shutdown must be checked in order to make sure the model is in a safe place and is capable of shutting down properly.
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 key objective is to be able to keep the telehandler upright, but surely there are dangers.
The rear-axle pivot point, and the two front wheels make up the telehandler's triangular base. Typically the rear axle oscillates and therefore, the rear wheels are not a 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 the boom is down, adding a load to the forks at that same time moves the center of gravity down and forward. Lifting the load will move the center of gravity to the rear and upwards. At the same time, when this happens, the stability triangle shrinks. Thus, the higher you lift a load, the less of a margin for error you have since 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 can change the stability triangle and leave less room for the frame to remain balanced if it is not perfectly level. 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 would not be oriented over the equipment's centerline. The stability triangle is always aligned with the centerline of the equipment.
