There are 5 important steps to making certain that safety is a main concern. The initial step is completing a Walk-Around Inspection to be able to insure that the model 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 determine whether or not the model is functioning in a safe manner. The 4th thing to take into account is Proper Operation, in order to know whether or not the model is safely working. Lastly, Proper Shutdown must be checked in order to make sure the unit is in a safe place and is capable of shutting down properly.
At the center of the 5 steps and this regulation, there is a machine that lifts heavy weights to impressive heights and stands on a triangular footprint. The key goal is to be able to keep the telehandler upright, but for sure there are risks.
The triangular base of the telehandler comprises the rear-axle pivot point and the two front wheels. The rear axles often oscillates, hence the rear wheels are not considered part of the base. The telehandler remains upright so long as the machine's center of gravity, that is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented inside the stability triangle.
When a load is positioned on the forks while the boom is down, the center of gravity forward and down. The load if lifted will move the center of gravity upwards to the rear. At the same time, when this occurs, the stability triangle shrinks. Therefore, the higher you lift a load, the less of a margin for error you have since 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 completely level. For instance, imagine the center of gravity resembling a plumb bob hanging from the boom. You would 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 machine. The stability triangle is continuously aligned with the centerline of the equipment.
