There are 5 key steps to ensuring safety is a main concern. The initial step is completing a Walk-Around Inspection to be able to insure that the unit is visually safe. Next check if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step in order to know whether or not the unit is functioning in a safe manner. The 4th thing to think about is Proper Operation, in order to determine whether or not the unit is working safely. Lastly, Proper Shutdown should be checked in order 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 goal is to be able to maintain the telehandler upright, but for sure there are risks.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Normally the rear 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 machine's weight is balanced, stays oriented in the stability triangle.
When a load is placed on the forks while the boom is down, the center of gravity forward and down. The load if raised would change the center of gravity upwards to the rear. At the same time, the stability triangle shrinks when this happens. Thus, the higher you lift 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 right or left. 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 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 telehandler's centerline.
