What is the difference between a bridge crane and gantry crane?
A gantry crane is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on rails that are embedded in, or on top of the floor or ground structure.
What type of crane has a bridge?
Double Girder Crane Double girders are bridge cranes that have two i-beams or “girders” which support their load. These are the heavier type of bridge cranes and they have more lifting capacity than single girder cranes.
What are the uses of cranes?
A crane is a type of machine commonly used in construction, generally equipped with an elevator, ropes or chains and sheaves that can be used both to move and to lift and lower materials horizontally. It is mainly used for heavy lifting and transport to other locations.
What is hoist in crane?
A hoist is a device used for lifting and lowering loads while a crane is a device used for moving loads in different directions. A hoist can only move loads vertically while a crane can move loads vertically and horizontally.
What type of crane has a bridge supported by two or more legs?
If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane (USA, ASME B30 series) or a goliath crane (UK, BS 466).
What is a hammerhead crane?
Definition of hammerhead crane : a heavy-duty crane with a horizontal counterbalanced jib.
Why are cranes important?
Cranes are a big part of lifting mechanism and performs a crucial role in the project as a whole. Cranes are not only essential for the construction industry; moving heavy materials, loading and unloading but also important equipment used in various sectors such as mining, marine, civil aviation and more!
What industries use cranes?

What are the 3 types of hoists?
There are three types of residential hoisting devices:
- Wheeled hoists.
- Stationary hoists.
- Ceiling lifts.
What are hoists used for?
A hoist is a mechanical device that is used in healthcare to transfer physically disabled individuals from one place or position to another. Injuries (particularly back injuries) are common if manual lifting and handling of an individual is attempted due to the large strains placed on the body during this.
What is hydra crane?
With a Hydra machine, one can both lift and carry the load of the material while the materials or the load can only be lifted and not carried by the cranes. Capacity- The weight capacity of the crane is more than that of a hydra machine. Stability- A crane is a more stable option.
What is a boom crane?
A boom truck crane, or a telescoping crane, uses high-boom angles and a hoist to lift loads. These cranes are designed for strength and stability and are typically used to lift heavy loads vertically.
What exactly is a free standing bridge crane?
Free standing bridge crane is kind of light and small lifting equipment , it is used for lifting and transporting materials in the small factory or storage, especially for modern production line. Workstation freestanding crane has many advantages, such as wide application, light weight, low headroom, easy to install and repair.
What is the difference between Crane and hoist?
Difference Between Hoist and Crane. Summary: 1.A hoist is a device used for lifting and lowering loads while a crane is a device used for moving loads in different directions. 2.A hoist is a simple device while a crane is a more complex device. 3.A hoist can only move loads vertically while a crane can move loads vertically and horizontally.
What are the components of a crane?
Common Crane Parts. Crane parts are mechanical components of a crane where there is clearly a mechanism with moving parts. A crane is a form of machine which is usually equipped with a hoist, chains or wire ropes and sheaves which can be used to both lift and lower materials and to move them horizontally.
What is a 5 ton crane?
5 ton gantry crane is a kind of versatile crane that is used both indoors and outdoors. It can be constructed in many different ways to serve almost all sorts of applications. The crane consists of a steel frame that has single beam or double beams and supporting columns that run along rails mounted on the floor level or run on wheels.
