There are 5 key steps to making sure that safety is a main concern. The first step is completing a Walk-Around Inspection to be able to assure that the model is visually safe. Then assess if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the unit is working safely. The 4th thing to think about is Proper Operation, in order to determine whether or not the model is operating safely. Last of all, Proper Shutdown needs to be checked in order to make certain the model is in a safe place and is capable of shutting down correctly.
There is a machine that 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 be able to maintain 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. Normally the back axle oscillates and therefore, the back wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the machine, which is defined as the point in 3 dimensions around which the equipment's weight is balanced, stays oriented in the stability triangle.
When the boom is down, adding a load to the forks at that time changes the center of gravity forward and down. Raising the load would move the center of gravity upwards and to the rear. At the same time, when this happens, the stability triangle shrinks. Hence, 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 that can 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 can 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 continuously aligned with the centerline of the machine.
