Railroad crane

Railroad Cranes run on train tracks. They move loads in and out of train cars. They can lift very heavy loads. Railroad cranes can even lift train cars.Train cars are heavy. In an accident, they may leave the tracks. The cranes can pick them up and put them back

Overhead crane

Also known as a 'suspended crane', an overhead crane works 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.

Hammerhead crane

The "hammerhead", or giant cantilever, crane is a Fixed-jib crane consisting of a steel-braced tower on which revolves a large, horizontal, double cantilever; the forward part of this cantilever or jib carries the lifting trolley, the jib is extended backwards in order to form a support for the machinery

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, which is a style of cranes in case of which a horizontal portion called the boom or the jib supports a moveable hoist and is generally attached firmly to a wall or a pillar fixed to the floor. This type of

Tower crane

Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete slab, tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall buildings. The base is then attached to the mast which gives the crane its height. Further the

Giant Cantilever Crane

Also known as a hammerhead crane, the giant cantilever crane is a Fixed jib crane consisting of a steel braced tower, on which revolves a large horizontal double cantilever. The forward part of this cantilever or jib carries the lifting crab, and the jib is extended backwards in order to form a support for the machinery

Cranes

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 vehicles. Cranes are operated either through cab operator or through infrared or radio signals.

Tower Crane

while enjoying an excellent view of the load and its surroundings at all limes. The use of tower crane has become synonymous with medium- to high-rise construction, be it for buildings or for bridges, dams, cooling towers, etc. Tower cranes can be Fixed or can be mounted on rails. In the latter case, it is referred to as travelling tower crane. Sites with multiple tower cranes in operation are very common these days, especially for fast-track construction projects.

Gantry Crane

type of portable material handling equipment used in job station or secondary task areas. Gantry cranes are quite similar to overhead cranes except that the bridge which carries trolley is rigidly supported on two or more legs running on Fixed rails.

Mobile Cranes

Cranes are the huge tower like machineries having ropes meant to lift or to lower any heavy device. Cranes are not permanent structure. In fact it is a temporary structure either Fixed in the ground or mounted on certain vehicles. Cranes are operated either through cab operator or through infrared or radio signals. The important equipments of the cranes are mast, base, jib and motor. Stationary cranes are fixed whereas mobile

  • FACTORS BEHIND THE SELECTION OF CONSTRUCTION EQUIPMENTS

    • decision. For example, the soil and profile of a site may dictate whether to go for a crawler-mounted equip- ment or a wheel-mounted equipment. If there is a power line at or in the vicinity of site, one may go for a Fixed-base kind of equipment rather than a mobile kind of equipment. Similarly, climatic conditions such as the presence of strong winds, visibility level and noise level may affect equipment-selection decision. Further, the access leading to

  • Guy Derrick

The lead lines run into the derrick base, which is Fixed in position, over sheaves and out to the winch. Because the lead lines run through the center of rotation, they do not encumber the swing motion. The mast must be held close to plumb by the guys; excessive lean will make swinging difficult to
