Gantry cranes are portable, lightweight, and affordable lifting solutions with sturdy A-frame design. Gantries have many great features such as height adjustment, span adjustment and the heavy-duty casters. As with any good thing there comes the possibility of misuse. Below are five of the most common misuses to avoid.
Let’s think about what is more stable- a 4 leg bar stool or 3 leg? You can ask the same of a 4 leg or 3 leg bridle sling.
How about the use of 4 machine skates versus a load equalizing dollies? Stools, slings or load equalizing dollies, the reality is that when a load is applied, the weight is usually distributed unevenly.
The majority of times, the 3 leg will dominate stability. There are a couple exceptions to this, but if this theory is dismissed or forgotten, mishaps can happen.
For example, if a load is being off-loaded be means of a crane, likely the off-set center of gravity has not been precisely calculated or located.
So when was the last time you took the oil plug out of the bottom of your car and drove it around, expecting for the performance to increase?
