There are 5 important steps to making certain that safety is a main concern. The initial step is completing a Walk-Around Inspection in order to insure that the model is visually safe. Then check if the work location is safe to use with a Worksite Assessment. The Function Test is the third step so as to determine whether or not the unit is working safely. The 4th thing to take into consideration is Proper Operation, so as to know whether or not the model is safely working. Lastly, Proper Shutdown must be checked so as to make sure the model 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 machinery 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 surely there are dangers.
The rear-axle pivot point, and the two front wheels make up the telehandler's triangular base. Typically the back axle oscillates and thus, the back wheels are not a part of the base. The telehandler remains upright so long as the equipment's center of gravity, that is defined as the point in 3 dimensions around which the weight of the machine is balanced, stays oriented in the stability triangle.
When a load is placed 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 upwards to the rear. At the same time, the stability triangle shrinks when this occurs. Hence, the higher you lift a load, the less of a margin for error you have since the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move right or left. It is this wandering action that can change the stability triangle and leave less room for the frame to remain balanced if it is not completely level. Like for example, 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 always aligned with the equipment's centerline.
