To make sure that safety is a main concern, there are 5 key steps. To be able to ensure that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Then check 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 think about is Proper Operation, so as to know whether or not the model is operating safely. Last of all, Proper Shutdown should 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 machinery which stands on a triangular footprint and lifts heavy weights to impressive heights. The main objective is to be able to maintain the telehandler upright, but surely there are dangers.
The two front wheels, and the rear-axle pivot point make up the telehandler's triangular base. Typically the rear axle oscillates and thus, the rear wheels are not a 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 machine's weight is balanced, stays oriented in the stability triangle.
When a load is positioned on the forks whilst the boom is down, the center of gravity down and forward. The load if lifted would change the center of gravity to the rear 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 as 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. For example, imagine the center of gravity resembling a plumb bob hanging from the boom. You would always be able to 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 will not be oriented over the centerline of the machinery. The stability triangle is always aligned with the equipment's centerline.
