There are 5 important steps to making certain that safety is a top priority. The first step is completing a Walk-Around Inspection in order to assure that the unit is visually safe. Next assess if the work place is safe to use with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is working in a safe manner. The 4th thing to consider is Proper Operation, in order to determine whether or not the model is safely working. Lastly, Proper Shutdown should be checked in order to make sure the unit is in a safe place and is capable of shutting down correctly.
There is a machinery which 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 for sure there are dangers.
The telehandler's triangular base consists of the rear-axle pivot point and the two front wheels. The rear axles usually oscillates, hence the rear wheels are not considered part of the base. The telehandler remains upright so long as the machine's center of gravity, which is defined as the point in 3 dimensions around which the equipment's weight is balanced, stays oriented inside the stability triangle.
When a load is placed on the forks while the boom is down, the center of gravity down and forward. The load if lifted will move the center of gravity to the rear upwards. At the same time, the stability triangle shrinks when this occurs. Hence, the higher you raise 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 left or right. This wandering action could change the stability triangle, leaving 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 machinery. The stability triangle is always aligned with the centerline of the telehandler.
