CRANEMobile

A mobile cranes are machine that could lift, pull, tug, carry, and do many such things that are done on a large scale. It is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. They are commonly used in the construction industry and in the manufacturing of heavy equipment.

MobileCrane?

Ancient Greeks The first known construction cranes were invented by the Ancient Greeks and were powered by men or beasts of burden, such as donkeys. These cranes were used for the construction of tall buildings

History

Ancient RomanThe heyday of the crane in ancient times came during the Roman Empire, when construction activity soared and buildings reached enormous dimensions. The Romans adopted the Greek crane and developed it further and called tread wheel crane. We are

relatively well informed about their lifting techniques, thanks to rather lengthy accounts by engineers Vitruvius

History

Middle AgesDuring the High Middle Ages, the tread wheel crane was reintroduced on a large scale after the technology had fallen into disuse in western Europe with the demise of the Western Roman Empire. The earliest reference to a treadwheel (magna rota) reappears in archival literature in France about

1225,followed by an illuminated depiction in a manuscript of probably also French origin dating to 1240.In navigation, the earliest uses of harbor cranes .History

Application

Advantages

Mobility: All-wheel drive steering suspension system

Maneuverability: Can easily move through sand and gravel as well as travel smoothly on asphalt roads and highways. It has the capability to travel from site to site independently.

Strong lifting capacity: Capacity ranges from 40 to 1,000 tons and reaches heights of up to

500 feet offering both power and precision

Advantages

Speed: Capable of reaching speeds up to 55 miles (88 Km) per hour.

Compact: Compact design is a combination of a truck-mounted crane and a rough-terrain crane

Efficiency: Integrated attached booms are part of the cranes and travel with them

Advantages

Adjustability: With the mobile undercarriage and hydraulic boom, these cranes can easily adjust on the job site to meet any requirements.

Agility: Offer the agility and function of a pick-and-carry rough terrain crane

Versatility: Ideal for completing numerous lifting tasks in no time and for moving from one construction site to another without difficulty.

Advantages

Durability and comfort: Built to handle tough job site conditions, while at the same time providing comfort and ease for operators. This allows them to work more effectively for longer days with less fatigue.

Safety: Even though they are compact, they still offer exceptional visibility from the cab in order to help operators have a full view of the work area

Rough Terrain CraneA 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.

Types

Truck Mounted CraneCranes mounted on a rubber tire truck will provide

great mobility. Outriggers that extend vertically or horizontally are used to level and stabilize the crane during hoisting

Types

All Terrain Crane A mobile crane with the necessary equipment to travel at speed on public roads, and on rough terrain at the job site using all-wheel and crab steering. AT‘s combine

the road ability of Truck- mounted Cranes and the maneuverability of Rough Terrain Cranes

Types

Loader CraneA loader crane is a hydraulically powered articulated arm fitted to a trailer, used to load equipment onto a trailer. The numerous sections can be folded into a small space when the crane isn’t in use.

Types

Crawler CraneA crawler crane is a crane mounted on an

undercarriage with a set of tracks that provide stability and mobility. Crawler cranes range in lifting capacity from about 40 to 3,500 short tons

Types

Telescopic CraneThis 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.
