There are 5 important steps to making certain that safety is a top priority. The first step is completing a Walk-Around Inspection in order to assure that the unit is visually safe. After that assess if the work location is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to know whether or not the model is safely working. The 4th thing to think about is Proper Operation, in order to know whether or not the model is operating safely. Last of all, Proper Shutdown must be checked so as to make certain the unit is in a safe place and is capable of shutting down correctly.
At the center of the 5 steps and this regulation, there is a machine which lifts heavy weights to impressive heights and stands on a triangular footprint. The key objective is to be able to keep 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 hence, the back wheels are not a part of the base. The telehandler remains upright as long as the machine's center of gravity, which is defined as the point in 3 dimensions around which the machine's weight 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 down and forward. Lifting 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 raise 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 right or left. It is this wandering action that 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 the center of the ground and a point on the boom. 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 equipment's centerline.
