To ensure that safety is a main concern, there are 5 key steps. In order to make sure that the model is visually safe, the initial step is to perform a Walk-Around Inspection. Then assess if the worksite is safe to operate in with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the model is safely functioning. The 4th thing to consider is Proper Operation, in order to determine whether or not the unit is safely operating. Last of all, Proper Shutdown has to be checked in order to make sure the model is capable of shutting down properly and is in a safe place.
There is a machine which lifts heavy weights to impressive heights upon a triangular footprint at the center of the 5 steps and this regulation. The key goal is to maintain the telehandler upright, but surely there are dangers.
The triangular base of the telehandler consists of the two front wheels and the rear-axle pivot point. The rear axles usually oscillates, therefore the rear wheels are not considered part of the base. The telehandler remains upright as long as the machine's center of gravity, that is defined as the point in 3 dimensions around which the weight of the equipment is balanced, stays oriented inside the stability triangle.
When a load is placed on the forks whilst the boom is down, the center of gravity forward and down. The load if lifted will change the center of gravity to the rear upwards. At the same time, the stability triangle shrinks when this happens. Hence, the higher you lift a load, the less of a margin for error you have because the stability triangle lessens.
With a stable but small 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 completely level. For example, imagine the center of gravity resembling a plumb bob hanging from the boom. You will 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 would not be oriented over the equipment's centerline. The stability triangle is continuously aligned with the telehandler's centerline.
