Rough terrain crane

similar to a crawler crane. In a rough terrain crane, the engine is usually mounted in the undercarriage rather than in the upper, as with crawler crane. Rough-terrain cranes have high mobility and can work best if combined with the operation of a tower crane

Cranes

Development depends on infrastructure and infrastructure on heavy machineries. Of all the heavy machines cranes acquire an important position as they are involved in the building and maintenance of huge projects. Crane machines are the huge tower like machineries having ropes meant to lift or to lower any heavy devices. Hence they are also referred as lifting cranes. Cranes are not permanent structure. In fact it is a temporary structure either fixed in the ground or mounted on certain

Tower Crane

A tower crane is used to build very tall buildings. The crane be on the ground or on a floor in the building. As each floor is built, the crane is moved up. Tower cranes are one of the most important device that is used for the construction of huge buildings.

FAQ About Tower Crane Operation

  • Types of Cranes

    • of lifting operations, utilisation factors and degree of mobility required. Crane types can range from a simple rope and pulley or gin wheel to a complex tower crane but most can be placed within 1 of 3 groups namely mobile, static and tower cranes. Where Are Cranes Used? Cranes are used all over the world. They build tall skyscrapers in large cities. And, they help farmers in rural areas. Cranes are used near large bodies of water. They load and unload ships. Cranes are built

  • Tower Crane Superstructure

    • and easy for man-machine interaction. Hydraulic System Electronic proportional control, with combination of close/open type circuit, constant power and variable displacement pump system. Hydraulic system: winch, luffing gear, slewing gear, tower jib backstop, travel gear, auxiliary assembly system. Features:winch:lulling gear, travel gear are of open type system, main pump is constant power and variable displacement pump, variable displacement by hydraulic pilot control, with function

  • Tower crane lifting boom

    • tower crane lifting boom comprises main boom and fixed jib, the structural type is lattice structure of four tubular chords with intermediate equal section and two end variable section, main boom chord and web rod are made of domestic high quality

  • Crane History

    • where most cranes were used in cities with narrow streets, cranes tended to be built in the form of tall, slender towers, with the boom and the operator on top of the tower. Because quiet operation was important in crowded cities, these tower cranes were usually powered by electric motors when they became widely available. In the United States, cranes were often used in locations far away from residential areas. Cranes tended to be built with the boom connected to a trolley, which

  • Tower-mounted crane

    • three motions: the hook is raised and lowered by means of a winch and fall, carried in a circular path by the swing gear, and carried in a radial motion by either luffing the jib or rolling a trolley carriage on its underside. The simplest of tower cranes have only these motions, but more complicated arrangements include mechanisms that allow the base to roll on a track, the crane to change elevation by climbing, or the jib to articulate on a hinge point. In the twentieth century,

  • Construction Machinery Types and Applications

    • excavator, multi-bucket trencher   rolling excavators, milling excavators, tunnel boring machine etc.. Shovel soil transport machinery Such as bulldozers, scraper, Loaders, vehicles, flatbed and the dump truck and so on. Crane Such as tower cranes, self-propelled crane, derrick cranes, grab cranes, etc. Compaction machinery Such as tire roller, smooth wheel roller, single-foot roller, vibratory rollers, compaction machine, tamping machine. Piling Machinery Such as drilling

  • Bottom-Slewing Tower Cranes Structure and Configuration

    • The main parts of a typical bottom-slowing tower crane include: Undercarriage. Unlike top-slowing cranes, which are often configured without an undercarriage, bottom-slowing cranes would always have an undercarriage to connect between the ground or any other supporting surface and the slewing

  • Wind and Tower Cranes

    • Like most mobile rigs, self-erecting cranes can fold up on short notice. All other tower cranes must ride out severe storms. That requirement has induced engineers to identify two principal classes of load combinations germane to the design of these machines: hi-service loads act on the crane in operation, and out-oj-service loads occur
