To make certain 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. Then 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 model is working in a safe manner. The 4th thing to think about is Proper Operation, so as to know whether or not the model is operating safely. Lastly, Proper Shutdown must be checked in order to make sure the unit is capable of shutting down properly and is in a safe place.
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 key goal is to be able to maintain the telehandler upright, but for sure there are dangers.
The telehandler's triangular base comprises the rear-axle pivot point and the two front wheels. The rear axles normally oscillates, hence the rear wheels are not considered 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 the boom is down, adding a load to the forks at that same time changes the center of gravity down and forward. Raising the load will move the center of gravity upwards and to the rear. At the same time, when this occurs, the stability triangle shrinks. Thus, the higher you lift 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 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 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 equipment. The stability triangle is continuously aligned with the machine's centerline.
