There are 5 key steps to making certain that safety is a main concern. The initial step is completing a Walk-Around Inspection in order to assure that the unit is visually safe. After that assess if the work place is safe to utilize with a Worksite Assessment. The Function Test is the third step in order to determine whether or not the unit is safely functioning. The 4th thing to take into account is Proper Operation, so as to determine whether or not the unit is operating safely. Lastly, Proper Shutdown should be checked in order to make certain the unit is capable of shutting down properly and is in a safe place.
At the center of the 5 steps and this regulation, there is a machine that stands on a triangular footprint and lifts heavy weights to impressive heights. The key goal is to be able to keep 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 often oscillates, thus the back wheels are not considered part of the base. The telehandler remains upright as long as the center of gravity of the equipment, that is defined as the point in 3 dimensions around which the weight of the equipment is balanced, stays oriented in the stability triangle.
When the boom is down, adding a load to the forks at that time moves the center of gravity forward and down. Raising the load will move the center of gravity upwards and to the rear. At the same time, when this happens, 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.
With a small but stable stability triangle, it leaves less room for the center of gravity to move right or left. This wandering action can change the stability triangle, leaving less room for the frame to remain balanced if it is not perfectly 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 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 centerline of the machine. The stability triangle is continuously aligned with the centerline of the equipment.
