Q:How do you get heavy weights on top of a crane?
What okorder.com/... Always wanted to see one erect itself, they just seem to spring up overnight. Wingman
Q:Hunger Games Seneca Crane question?
Nope. He is just called The Gamemaker in The Hunger Games. I guess they wanted to elaborate on him more so that you would know Katniss's hatred for him in the Catching Fire movie.
Q:hhydraulic crane?
Do okorder.com
Q:SWL and Capacity for Cranes...?
Example: Suppose a crane is rated for a safe working load of 10,000 pounds. To verify that it can safely handle that load it will be tested by lifting a much heavier proof load. So its capacity must be greater than its safe working load.
Q:I'm afraid of crane flies?
I'm glad i'm not the only one scared of crane flies! They're huge and when you crush them eggs or poop come out. ;A;
Q:Origami Crane Myth.......?
it's true that there is a belief in folklore that making 1000 paper cranes is lucky,or grants a wish. I can't testify to the actual truth of the folklore as I have never made 1000 cranes,but on the surface, it would not seem to follow the laws of probability or physics.
Q:how to do tower crane maintenance?
Tower cranes in construction is being inspected as part of everyday maintenance. Usually, Safety In charge or a mechanical engineer do the inspection on site. Some pointers for inspection are: 1. Machine checking including motor 2. Emergency break 3. Lifting cable checking 4. Power panel 5. others Not only the tower crane is being checked, the operator and rigger also attends daily safety toolbox to update themselves on daily safety hazards on site
Q:Why did Dr. Crane work for Ra's Al Ghul and with Falconie?
Crane was a criminal and a bit of a nut. Just like any super villain. He had a fetish for fear. Ra's used him because Crane could make best use of the blue flower drug, and they need Falconie to set things up. Ra's would have gotten rid of both after he was done.
Q:What is the tax basis under the Crane Doctrine?
Your understanding of Crane is correct. For purposes of calculating the gain on sale, the basis would be $100k. What Crane really said was that the net proceeds would have to include any assumed debt, in addition to any cash received -- basically that you had to include the debt on both ends of the transaction if my reading is correct. (That jives with the example in Commissioner v Tufts et al, 81-1356 so I think we're correct on that.) Where basis gets interesting is when you are calculating depreciation. At least when you convert a residential property to business use -- i.e. a rental -- you use the LESSER of the cost basis (Crane) or the FMV on the date that the property is placed in business(rental) service. In your example, the depreciable basis would be $80k since that was the lower. For calculating the gain on sale, the cost basis would still be $100k (adjusted down for any depreciation allowed or allowable while in business use of course).
Q:How do the cranes used to build tall buildings get put in place?
Large cranes are built in sections imagine like an erector set. When there is a large building to be built the crane arrives in smaller easier to manage pieces and assembled on site.
