"Lifting appliance" means:- "An

  • Crane History

    • cranes tended to be powered by internal combustion engines. During the 1950s, the availability of stronger steels, combined with an increased demand for taller buildings, led to the development of cranes with very long booms attached to Small trucks, or to crawlers with caterpillar treads. Mobile cranes and tower cranes of many different kinds are used extensively in construction sites around the world.

  • Raw Materials of manufacture cranes

    • The most important substance used to manufacture cranes is steel. Steel is an alloy of iron and a Small amount of carbon. For structures that do not require very high strength, a common form of steel known as carbon steel is used. By definition, carbon steel contains less than 2% of elements other than iron and carbon. Carbon steel exists in

  • Overhead Crane and Bridge Crane

  • Hydraulic Telescoping Gantries

    • with as many as five stages and fully extended height of as much as 45 ft (13.7 m). The capacity for a pair of units can be 1000 tons (900 t) or more, but the capacity reduces with cylinder extension. The stages sequentially extend with the Smallest diameter, and hence the weakest stage at the top. The lifting ability, structural strength, and structural stability of gantry legs depend entirely on the cylinders. Because lateral strength is limited by these cylinders behaving as a cantilevered

  • Tower-mounted crane

    • ease of coordinating multiple tower cranes is an advantage. There are niche markets for these as well; cable stay and suspension bridges, offshore oil platforms, and power plants are some examples. In most of the world outside U.S., Small tower cranes are used for modest-size residential and commercial projects. Many of these rigs are self-erecting machines that are pulled to the site by truck. In North America, similar work woulc utilize a small telescopic crane. Gradually,

  • Crane and Mobile Crane

    • equipment could be used right up to the point of tipping over. Both cranes and aircraft of early vintage were machines with modest capabilities that responded almost like extensions of the operators themselves. Machines were relatively Small and inexpensive, and pilots frequently survived crashes while crane operators usually walked away. Collateral damage to persons and property was usually inconsequential. Not so today where property damage claims can be stratospheric and the

  • Industrial Cranes

    • cylinder and wire luffing cranes, gantries, grab cranes and heavy lift cranes. Big cargo ships would require heavy lifter cranes. Sometimes, cranes installed are dependent on the products a cargo ship carries. Yachts however would only need a Smaller deck crane with shorter reach that can be sustained by the vehicle without toppling over when used. The deck cranes that are needed for a yacht may require the said minimum specs since yachts do not perform heavy lifting as compared to big boats

  • Articulating Jib Crane

    • jib cranes have a hinge or joint at the center of the horizontal section that lifts the load. This feature enables the user to bend or fold the arm if required. Since it can be folded, articulating jib cranes are easy to maneuver in Small areas with space restrictions. Mostly used in warehouses, large departmental stores and in the food industry, to name a few, articulating jib cranes are excellent equipments for lifting heavy loads in confined and small spaces. However,

  • Portable Jib Crane

    • By attaching a simple fork lift, any standard design of these cranes can be converted into a portable jib crane. Since the arm of the crane can rotate either partially or fully. Portable jib cranes have the ability to maneuver and move in Small spaces and hence come in handy for almost all general purposes. Another added advantage is their price that is not at all overboard and can be afforded by most people. Like all other varieties, portable jib cranes also have a manually driven

  • Gin Pole Derrick

    • Agirrlwle is the most elemental form of derrick-it could be described as primitive--essentially a leaning mast incapable of swinging and held in place by guys. With no boom, lifting is done from a load fall at the tip of the mast. Large and Small gin poles find roles quite distinct from one another. In the middle range alternative lifting devices are more practical, and so middle-sized poles are a rarity. Long heavy-duty gin poles operate at fixed radii with a lean of only 50 or 100 from
