Topic: How many crane types do you know?
Cranes are commonly used in the construction industry and in the manufacturing of heavy equipment. There are many crane types,a wide variety of brands, sizes, weights, and lifting capacity to suit any lifting needed anywhere in the world. While there are many different crane types,So how do the customers choose the crane that they need?

Overhead Crane
Also known as a ”suspended crane”, this type of crane work very similar to a gantry crane
but instead of the whole crane moving, only the hoist / trolley assembly moves in one direction along one or two fixed beams, often mounted along the side walls or on elevated columns in the assembly area of factory. Some of these cranes can lift very heavy loads.
Gantry Crane
A gantry crane has a hoist in a fixed machinery house or on a trolley that runs horizontally along rails, usually fitted on a single beam (mono-girder) or two beams (twin-girder). The crane frame is supported on a gantry system with equalized beams and wheels that run on the gantry rail, usually perpendicular to the trolley travel direction. These cranes come in all sizes, and some can move very heavy loads, particularly the extremely large examples used in shipyards or industrial installations. A special version is the container crane (or “Portainer” crane, named by the first manufacturer), designed for loading and unloading ship-borne containers at a port.
Jib Crane
A jib crane is a type of crane where a horizontal member (jib or boom), supporting a moveable hoist, is fixed to a wall or to a floor-mounted pillar. Jib cranes are used in industrial premises and on military vehicles. The jib may swing through an arc, to give additional lateral movement, or be fixed. Similar cranes, often known simply as hoists, were fitted on the top floor of warehouse buildings to enable goods to be lifted to all floors.
Mobile Crane (Wheel based or truck mounted)
One of the most powerful pieces of equipment in the construction business, mobile cranes are used for building and maintaining highways, bridges, buildings, pipelines and towers. They have a maximum height of about 400 feet and can lift hundreds of thousands of pounds.
Tower Crane
The tower crane is a modern form of a balance crane. When fixed to the ground, tower cranes will often give the best combination of height and lifting capacity and are also used when constructing tall buildings.
A tower crane is usually assembled by a telescopic jib (mobile) crane of greater reach (also see “self-erecting crane” below) and in the case of tower cranes that have risen while constructing very tall skyscrapers, a smaller crane (or derrick) will often be lifted to the roof of the completed tower to dismantle the tower crane afterwards.It is often claimed that a large fraction of the tower cranes in the world are in use in Dubai. The exact percentage remains an open question.
Telescopic Crane
This type of crane offers a boom that consists of a number of tubes fitted one inside of the other. A hydraulic mechanism extends or retracts the tubes to increase or decrease the length of the boom.The relative compactness of telescopic booms make them adaptable for many mobile applications.Note that while telescopic cranes are not automatically mobile cranes, many of them are. These are often truck-mounted.
Rough Terrain Crane
A crane that is mounted on an undercarriage with four rubber tires, designed for operations off road. The outriggers extend vertically and horizontally to level and stabilize the crane when hoisting. These types of cranes are single engine machines where the same engine is used for powering the undercarriage as it is for powering the crane. In these types of cranes, the engine is normally mounted in the undercarriage rather than in the upper portion.
crane machine types also include crawler crane,floating crane and railroad Crane etc,.Dongqi crane can provide you crane types such as overhead crane,gantry crane,jib crane. In the same time,DQCRANES is capable of design complex crane projects from 5t-500t outdoor gantry cranes, jib cranes and container cranes to 0.5 t -500 t indoor lifting systems for various industries.
