Product Description:

Brief Description:


Tower crane 4808 is used to lift building material such as concrete, steel bars vertically and horizonally.

All tower cranes consist of the same basic parts:

1. The base is bolted to a large concrete pad that supports the crane.

2. The base connects to the mast (or tower), which gives the tower crane its height.

3. Attached to the top of the mast is the slewing unit (large ring-gear and motor) that allows the

crane to rotate.

4. Attached to the slewing unit is the jib (or boom), the machinery arm, the counterweights

 and, the Operators cabin

Q:calculating psf in regaurdto crawler cranes?
Not sure what you are asking exactly... Are you saying that you have a crane with a capacity of 100 tons and you want to know the pressure on the soil where the crane is positioned? In this case, you take the capacity (in pounds) plus the weight of the crane (in pounds) then divide their sum by the area of the tracks on the crane (in square feet). This will result in pounds per square foot or psf as you wrote above. These are example estimates, they may not be anywhere near the correct answer, this is simply how to do the calculation. Assumed Capacity 100 ton = 200,000 lbs. Assumed Weight 105 ton = 210,000 lbs. Assumed Area of Track = 200 square feet Note: 1 U.S. ton = 2,000 pounds = 2,000 lbs. 410,000 lbs / 200 square feet = 2,050 psf There's a start, now you just need to find out how much it actually weighs and how long and wide the tracks are to get the area of the track on the ground. I hope that answers the question you were asking.

Crane FLIES not cranes. The winter crane fly has an abundant hatch--well, during early spring or late winter. In this they are just everywhere--this species just does this sort of thing. Typically crane flies are a rather rare sight, such as during the summer months, usually of an entirely different species. There's really not much to explain their abundance.
