The electro-magnet can be switched on and pick up metal. Then the electro-magnet can be switched off and the metal will be released. A natural magnet would not release the metal.

Safe working loads of engine cranes depends on what factor.?
Safe working loads of engine cranes depends on the safety factor. It also depends on MBL or Minimum Breaking Load, the force required to make the lifting device yield or fail.
Why do vehicles designed to carry heavy loads have multi-wheel axles?
the vehicles carrying heavy loads are provided with multi-wheel axles to increase the area and decrease the pressure.
What is the purpose of the counterweight of the forklift?
To aid weight distribution with heavy loads.
How many tons can an average crane lift?
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.
What is a windlass used for?
A windlass is used to move heavy weights. They usually have a horizontal barrel that is turned with a belt or handle.
What are the advantages of using cranes in construction?
It is a way of getting heavy loads up to tall places.
What is HOTcrane?
Hot Environment Cranes / Electric Overhead Cranes are used in metal refineries where heavy loads that are at a high temperature need to be moved around.
Do all construction jobs require gantry cranes?
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.
Why are permanent magnets not used in cranes to lift heavy loads?
They can become demagnetized by impact, if they're picking up something which is also magnetic (which steel is), the magnet would need to be changed when the polarity was wrong, and then there's the matter of how you detach the magnet once you got the load into place.
Why are magnets used?
Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
How cranes lift heavy loads without toppling?
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
Do sheep carry heavy loads?
Sometimes, in the old days, sheep would carry heavy loads.
What equipment is used for moving?
As I have some experience in handling machinery to move heavy equipment, my observation is that moving heavy equipment typically requires specialized tools designed specifically for this purpose. Here are some examples: Cranes: Cranes are one of the most common types of equipment used for heavy equipment moving services in California. They come in various sizes and types, including mobile cranes, tower cranes, and overhead cranes, and can lift and move loads weighing thousands of pounds. Forklifts: Forklifts are designed for moving heavy loads over short distances. They are particularly useful for lifting and moving machinery that needs to be loaded onto trucks or moved around a factory or warehouse. Flatbed Trucks: Flatbed trucks are used for transporting heavy equipment over long distances. They have a flat, open bed that can accommodate large, heavy loads and are equipped with ramps or lifts to make loading and unloading easier. Heavy-duty Trailers: Heavy-duty trailers are specifically designed for transporting oversized or overweight loads. They are often used in combination with tractors or other heavy-duty vehicles. Rollers and Skates: Rollers and skates are used for moving heavy machinery over short distances on smooth surfaces. They are particularly useful for moving machinery around a factory floor or loading dock. Rigging Equipment: Rigging equipment includes chains, slings, and straps that are used to secure and lift heavy equipment. This equipment is often used in combination with cranes or other lifting devices. Hydraulic Jacks: Hydraulic jacks are used to lift heavy loads off the ground. They are particularly useful for lifting machinery that needs to be moved vertically, such as a press or a large engine. Overall, the choice of equipment will depend on the specific needs of the job, including the weight and size of the machinery, the distance it needs to be moved, and the terrain and environment it will be moved through.
How much weight can the average construction crane lift?
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.

What did Romans use oxen for?
The Romans used oxen for hauling heavy loads. Although oxen were slower than mules, they were hardier and stronger and could pull heavy loads such as military siege equipment.The Romans used oxen for hauling heavy loads.

What did you observe when testing the various loads?
heavy loads dont go as fast
