To make certain that safety is a main concern, there are 5 important steps. In order to make certain that the model is visually safe, the initial step is to perform a Walk-Around Inspection. Next assess if the work location is safe to use with a Worksite Assessment. The Function Test is the third step in order to know whether or not the unit is working in a safe manner. The 4th thing to think about 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 sure the unit is capable of shutting down properly 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 key objective is to be able to maintain the telehandler upright, but surely there are dangers.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Usually the back axle oscillates and therefore, the rear wheels are not a part of the base. The telehandler remains upright so long as the equipment's center of gravity, 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 forward and down. Lifting the load will change the center of gravity upwards and to the rear. 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 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. For example, 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 centerline of the equipment. The stability triangle is always aligned with the centerline of the machine.
