Offshore cranes generally have a high standard range of backlash. This applies mainly to the slewing gear of these cranes.
A block and tackle. an ellevator, a winch,
Electric Overhead Travelling (EOT) Electrical Overhead Travelling (EOT) cranes are simplest type of cranes used in industries for maintenance purpose(mostly). The capacity can go up to 50tons. The Indian standard for the EOT crane is IS3177. Some of the EOT crane manufacturers in India are LOADMATE, EDDY cranes, Armsel MHE pvt ltd.......
Because anticlockwise torque is equal to clockwise torque and therefore the net torque is zero so the crane is in state of equillibrium and also there center of gravity pass through base therefore the cranes lift heavy load without toppling
According Cp if ur Crane is not contacting with any electrolyte like water, soil, means ther is no cp for atmospheric corrosion.

Construction canes are primarily used for lifting and moving heavy objects. Some of the types of construction cranes are the Sidelift crane, the Jib crane, the Gantry crane and the Tower crane.
As a matter of fact most of construction jobs do not need gantry cranes. The gantry cranes are mainly used at docks or at places where heavy loads like containers has to lifted and loaded on to trucks.

During the beginning of 2008 it was said that 30% of the world's cranes where working in Dubai construction.
Cranes. . . just joking!

Here's an easy breakdown: Small mobile cranes: Smaller cranes can raise around 5 to 20 tons. Truck-Mounted Cranes: Bigger truck-mounted cranes can deal with heavier loads, from 20 to 70 tons or more. Tower Cranes: Tower cranes, normally used in construction, can lift even heavier loads, ranging from 10 to over 20 tons. Crawler Cranes: Crawler cranes, regarded for their stability, can handle very heavy loads, ranging from 40 tons to numerous hundred tons. Floating Cranes: Floating cranes used in marine construction can raise enormous weights, frequently over 1,000 tons. Remember, these are general estimates, and the authentic lifting capacity relies upon the crane's specific model, setup, and working conditions. Operators and undertaking managers consider these elements to ensure secure and effective lifting on building sites.
It is a way of getting heavy loads up to tall places.
There was a one-shot Marvel-Dc crossover with Superman Versus Spider-Man they seemed to be dueling on a skyscraper under construction or a hammer-head crane. I recall this as I like Cranes. This was around l974. it was a special edition. normally Marvel and Dc- two rival comic houses- do not cooperate.
