- Q: who invented them and why do people make them?

- Q: For example, self lifting tower crane mounted to 10 meters or 2 floor use. How do you install the third floor now? Is it necessary to remove the crane?. Then add the length of the steel frame on the base seat, and then install the crane above him If so, then 2 cranes are needed.

- Q: Old used 200 t crawler crane is available for purchase. What are the guidelines/ thumb rules for assessing its cost ?
- Supply vs demand Extreme examples: If the crane is no longer needed anywhere, the cost will be 0; no demand. If the crane still has a unique useable function and there is only one available, it's immediate cost will be very high; no supply. So, assuming that the cranes supply/demand is somewhere in the middle, the methodology for assessing it's cost would be to evaluate the following: * Where is it located with respect to where it is needed? (place value) * How quickly do I need it, and how quickly can I get the crane? (time value) * What alternative solutions are available? * How much do other similar cranes cost? * etc Hope this helps!

- Im assuming it to be a modern Rolex Oyster 1/ it is much heavier than you would expect. 2/ the second hand appears to move in a continuous smooth motion rather than in individual 1 second ticks. 3/hold the face to your ear, you can actually hear the extremely rapid ticking 4/the face glass will not scratch nor break 5/when new it would be supplied in a green box containing rolex wallet etc. and Authentification certificate. My box and contents are in pristine mint condition, only ever opened once to take watch out when new. thus the box alone adds ?200 to value. 6/Any Rolex dealer will check the serial number for you. Also every reported lost/stolen Rolex is listed so dealer can check! 7/ Assume its dodgy, any Rolex dealer would buy it from him either for cash or in part exchange for any other watch! 8/ Rolex dealers all have secondhand watches for sale. 9/Decide if you really want a Rolex, they look superb but are not accurate time keepers! the inside is based on much cheaper Zenith movement. A Cartier is much better watch for the money! 10/ I bought my Rolex new and with hindsight wish Id bought a Cartier, which would have also held its value better. Take it to a Rolex dealer and have it appraised first. if he wont let you then walk away and buy from a real Rolex dealer, who will sell you secondhand for half new price, or less!
