To make sure that safety is a main concern, there are 5 key steps. In order to ensure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Next check if the worksite is safe to use with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the model is safely functioning. The 4th thing to think about is Proper Operation, in order to determine whether or not the model is safely operating. Last of all, Proper Shutdown has to be checked in order to make certain the unit is in a safe place and is capable of shutting down properly.
There is a machine that lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The main objective is to be able to maintain the telehandler upright, but surely there are dangers.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The rear axles usually oscillates, thus the rear 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 weight of the machinery is balanced, stays oriented inside the stability triangle.
When the boom is down, adding a load to the forks at that time moves 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 occurs. 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 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. 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 would not be oriented over the centerline of the machinery. The stability triangle is always aligned with the equipment's centerline.
