because we can't lift it with our hand
Gantry cranes are designed to lift extremely heavy products. Some Gantry cranes are extremely large and are used for ship building. These cranes straddle the ship allowing for large objects to be lifted or moved over the ship.
Electromagnets are used for a wide variety of uses like in motors to regulate the speed of motor and used in cranes to lift heavy metal objects and they can used in electronic devices
Tools like cranes, forklifts, hoists, and jacks are commonly used to lift heavy objects. They work by using mechanical force or hydraulic power to raise and move objects safely and efficiently.
Electromagnets are used for a wide variety of uses like in motors to regulate the speed of motor and used in cranes to lift heavy metal objects and they can used in electronic devices
A common machine used for lifting heavy objects is a crane. Cranes are equipped with cables, pulleys, and motors to hoist and move heavy loads to desired locations. They come in various designs such as tower cranes, mobile cranes, and overhead cranes to suit different lifting needs.
because you get to carry heavy stuff
A large crane used for lifting and moving heavy objects is typically called a mobile crane. These cranes are equipped with telescopic booms and wheels for mobility, allowing them to lift heavy loads and transport them to different locations on construction sites or other industrial settings.
Inclined planes are commonly used in everyday objects such as ramps, stairs, and highways for easier transportation of objects or people up and down. They are also used in heavy machinery like bulldozers and cranes to move materials more efficiently. Additionally, inclined planes are used in construction to lift heavy objects to higher levels.
Pulleys are used to lift or lower objects by changing the direction of the force applied. By using multiple pulleys in a system, mechanical advantage can be gained to make lifting heavy objects easier. They are commonly used in systems such as elevators, cranes, and weightlifting machines.
Electromagnets have several uses. They are used in cranes to pick heavy metal objects, to lift tiny metal scraps from wound by doctors, motor and generators, electric bells, loudspeakers, etc.
The tension rope pulley can be used to efficiently lift heavy objects by distributing the weight of the object across multiple pulleys, reducing the amount of force needed to lift it. This allows for a mechanical advantage, making it easier to lift heavy objects with less effort.
Tower cranes are most commonly used in construction industry and used both to lift and lower materials and to move them horizontally. Propose of Tower cranes is lifting heavy things and transporting to other places.
