Tower Crane supplier from Bangladesh

Tower Cranes standard defines a construction tower crane as: “a hammerhead, luffing, or other type of tower crane that is regularly assembled and disassembled for use at various sites. It is usually characterized by provisions to facilitate erection and dismantling and may include features to permit climbing or telescoping.”

Permanently mounted tower cranes are defined as: “a hammerhead, luffing, or other type of tower crane that is erected for longer term use at one location (five years or more). The configuration of the crane usually remains unchanged during the entire installation period.”

crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight, in the construction industry for the movement of materials and in the manufacturing industry for the assembling of heavy equipment.

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. Larger cranes were later developed, employing the use of human treadwheels, permitting the lifting of heavier weights. In the High Middle Ages, harbour cranes were introduced to load and unload ships and assist with their construction – some were built into stone towers for extra strength and stability. The earliest cranes were constructed from wood, but cast iron, iron and steel took over with the coming of the Industrial Revolution.

Gantry Crane Single/Double Girder supplier from Bangladesh

A gantry crane is a type of overhead crane with legs that support its bridge, trolley, and hoist. Larger gantry systems can travel on rail or track embedded in the ground, typically running in a straight line or covering a work area. Smaller gantry systems run on wheels or casters that can move throughout a facility for light fabrication work or maintenance.

Gantry crane is typically used for outdoor applications or lifting materials below existing overhead bridge crane systems. Manufacturing facilities, shipyards, scrap yards, railyards, special construction sites, steel mills, and other applications all use gantry cranes.

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. The crane legs travel on fixed rails embedded in, or laid on top of the floor.

Gantry cranes are considered when there is a reason not to incorporate an overhead runway system. They’re typically used in an outdoor applications where full beams and columns can’t be installed, or may be used below an existing bridge crane system. Gantry cranes can most commonly be found in shipyards, railyards, special outdoor projects like the construction of a bridge, or in places like steel mills where overhead room may be an issue.
