To make sure that safety is a main concern, there are 5 key steps. In order to make sure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Then assess if the work location is safe to use with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is functioning in a safe manner. The 4th thing to take into consideration is Proper Operation, in order to determine whether or not the unit is working safely. Last of all, Proper Shutdown needs to be checked in order to make certain the model is capable of shutting down properly and is in a safe place.
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 goal is to be able to keep the telehandler upright, but for sure there are dangers.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Typically the back axle oscillates and therefore, the rear wheels are not a part of the base. The telehandler remains upright so long as the machine's center of gravity, which is defined as the point in 3 dimensions around which the weight of the equipment is balanced, stays oriented inside 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 upwards and to the rear. At the same time, the stability triangle shrinks when this occurs. Therefore, the higher you raise a load, the less of a margin for error you have because the stability triangle lessens.
With a small but stable stability triangle, it leaves less room for the center of gravity to move left or right. This wandering action could change the stability triangle, leaving less room for the frame to remain balanced if it is not perfectly level. Like for instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You could always find the center of gravity somewhere 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 centerline of the machine. The stability triangle is always aligned with the equipment's centerline.
