There are 5 key steps to making certain that safety is a main concern. The first step is completing a Walk-Around Inspection to be able to insure that the unit is visually safe. Then assess if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is safely working. The 4th thing to consider is Proper Operation, in order to know whether or not the model is safely working. Last of all, Proper Shutdown must 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 stands on a triangular footprint and lifts heavy weights to impressive heights. The key objective is to be able to maintain the telehandler upright, but of course there are risks.
The telehandler's triangular base comprises the rear-axle pivot point and the two front wheels. The back axles usually oscillates, hence the back wheels are not considered part of the base. The telehandler remains upright as long as the center of gravity of the equipment, which is defined as the point in 3 dimensions around which the equipment's weight is balanced, stays oriented inside the stability triangle.
When a load is positioned on the forks whilst the boom is down, the center of gravity forward and down. The load if raised would move the center of gravity upwards to the rear. At the same time, when this occurs, 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.
With a small but stable stability triangle, it leaves less room for the center of gravity to move left or right. This wandering action can change the stability triangle, leaving 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 would 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 machinery. The stability triangle is always aligned with the centerline of the machine.
