To make sure that safety is a top priority, there are 5 important steps. In order to make sure that the unit is visually safe, the first step is to perform a Walk-Around Inspection. Next assess if the worksite is safe to use with a Worksite Assessment. The Function Test is the third step so as to know whether or not the unit is safely working. The 4th thing to consider is Proper Operation, in order to know whether or not the unit is safely operating. Last of all, Proper Shutdown should be checked so as to make certain the unit is capable of shutting down correctly and is in a safe place.
At the center of the 5 steps and this regulation, there is a machine that lifts heavy weights to impressive heights and stands on a triangular footprint. The key goal is 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 therefore, the rear wheels are not a part of the base. The telehandler remains upright as long as the center of gravity of the machine, which is defined as the point in 3 dimensions around which the weight of the machinery is balanced, stays oriented in the stability triangle.
When a load is placed on the forks while the boom is down, the center of gravity forward and down. The load if lifted will move 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 since 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. Like 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 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 equipment's centerline. The stability triangle is continuously aligned with the centerline of the machine.
