Filling out the electric hoist data sheet
Thread Content
What is the operating distance of an electric hoist? Is it the vertical distance it rises from the ground, plus the horizontal distance it moves after being lifted? Does \"span\" refer to the total length of the I-beam tracks on the roof? The data sheet shows a lifting height as well as an allowable lifting height for the equipment; is the former the actual height difference from the ground to the desired height, while the latter is the height difference from the ground to the roof tracks? I seek guidance from experts!
The span should be the distance between two rows of I-beams.
Lifting height refers to the distance that the hook rises from the ground to its maximum position, which is also the height to which the load can be lifted. The allowable lifting height refers to the distance between the hook at its highest position and the ground (when the steel wire rope is stretched to its limit)
