In practice, the cranes have to be "synchronized" which creates certain problems for controlling the lift. But as 40 + 40 = 80 there is ample overhead whentrying to lift 75 tons. The cranes would each lift opposite sides of the load at the same time.
Up to one ton, apparently..
It depends on how big it is and what type it is. We had a mobile (can be driven over the road) crane here last year that could pick up 500 tons. I hear they build mobile cranes that can lift as much as 750 tons. Stationary cranes can lift a lot more, but are harder to move.
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.
Depends on the length of the vehicle and the tare weight. Last tandem I drove, I could haul 15 tons on secondary roads, and 13-1/2 tons on the Interstate.
They're typically allowed, in the US, a gross vehicle weight of 54.000 lbs. How much that equates to in freight tonnage depends on the tare weight of the vehicle. A tandem dump truck can typically haul 15 tons. A tandem roll off with a 30 yard container is typically only good for 9 - 11 tons.
Typically, and legally, around 15 tons, give or take depending on the tare weight of the vehicle.
Well it depends on the type of crane and what it's intended use is. Wrecker cranes can weight anywhere from a 1,000 ~ 2,000 lbs right up to several tons. Larger commercial cranes can be in the neighbourhood of 10,000 lbs ( 5 tons ) and up to 20 tons *static weight (stationary ready to work).
About 25 tons.
That depends on the individual crane, the type of crane, the and the load. All lifting devices come with a Manufacturer's Capacity Plate attached to the device. This will give you the maximum load the device will carry at different stages or heights. It will also supply brief "load center" descriptions. this is important as loads lifted off center can cause tipping, structural failure and more accidents. There are many types of cranes too, from the Tower cranes seen in cities, Bridge cranes in factories, Mobile cranes on trucks, Hoists used in Auto shops, Jib cranes used by one person to lift things fast and easy, and ,many others and all lift varying weights.
In the US, typically 15 tons (give or take, depending on wheelbase and tare weight of the vehicle)
Only if they are operated in perfect synchronisation so that the load is always exactly equally shared between the two. That does depend, though, on the safety margin built into the cranes' ratings.
It is not mentioned the maximum weight Thor can lift. The myths and stories only state he is very strong.
