To make sure that safety is a main concern, there are 5 key steps. In order to make certain that the unit is visually safe, the initial step is to perform a Walk-Around Inspection. Next assess if the worksite is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to know whether or not the unit is safely functioning. The 4th thing to take into consideration is Proper Operation, in order to know whether or not the model is operating safely. Lastly, Proper Shutdown should be checked so as to make certain the model is in a safe place and is capable of shutting down correctly.
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 goal is to be able to maintain the telehandler upright, but surely there are risks.
The rear-axle pivot point, and the two front wheels make up the triangular base of the telehandler. Normally the rear axle oscillates and thus, the back wheels are not a part of the base. The telehandler remains upright so long as the center of gravity of the equipment, that is defined as the point in 3 dimensions around which the equipment'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 forward and down. The load if lifted would change the center of gravity to the rear upwards. At the same time, when this happens, the stability triangle shrinks. Thus, the higher you raise a load, the less of a margin for error you have as the stability triangle lessens.
When the stability triangle is small, it leaves less room for the center of gravity to move left or right. It is this wandering action which can change the stability triangle and leave 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 will always be able to 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 will not be oriented over the centerline of the machine. The stability triangle is always aligned with the machine's centerline.
