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 on the tracks. Railroad cranes can only lift things near the tracks. A railroad crane,

Gantry crane

a widely accepted alternative to overhead bridge cranes. This type of crane is similar to the bridge crane except that it runs on a runway at the floor level. The bridge is supported by a pair of rigid steel legs which are carried by a pair of end Trucks along the floor level runway. Gantry cranes often costs less than a bridge crane and built to heavy duty Class D specifications, which meet the demands of high duty cycles and multiple shift operation, as well as providing decades of reliable service

Rough terrain crane

Rough terrain crane is a crane mounted on an undercarriage with four rubber tires that is designed for pick-and-carry operations and for off-road and "rough terrain" applications. Outriggers are used to level and stabilize the crane for Hoisting. These telescopic cranes are single-engine machines, with the same engine powering the undercarriage and the crane, similar to a crawler crane. In a rough terrain crane, the engine is usually mounted in the undercarriage rather than in the upper,

Bridge Crane

A bridge crane runs on an elevated runway system along the length of a factory and provides three axis of Hook motion (X, Y, and Z). The hoist moves the load up and down, the trolley moves the load right and left, and the bridge of the crane moves the load forward and backward. Both single and double girder overhead traveling bridge crane designs allow very

Loader crane

A loader crane (also called a knuckle-boom crane or articulating crane ) is a hydraulically-powered articulated arm fitted to a Truck or trailer, and is used for loading/unloading the vehicle. The numerous jointed sections can be folded into a small space when the crane is not in use. One or more of the sections may be telescopic. Often the crane will have a degree of automation

Truck

A Truck, also named lorry, is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power and configuration, with the smallest being mechanically similar to an automobile. Commercial trucks can be very large and powerful, and may be

Crawler Crane

short tons (35.7 to 3,125.0 long tons; 36.3 to 3,175.1 t). Crawler cranes have better manoeuvrability and can be quickly relocated at different locations on a project site. However, for shifting to another project site, these cranes require a Truck or a trailer. The inability to be shifted from one site to another on its own is one of the main disadvantages of the crawler crane. Nevertheless, these cranes can work in difficult ground conditions. The cranes normally have lattice boom but are

Telescopic crane

A telescopic crane Has a boom that consists of a number of tubes fitted one inside the other. A hydraulic or other powered mechanism extends or retracts the tubes to increase or decrease the total length of the boom. These types of booms are often used for short term construction

Truck mounted crane

on highways, eliminating the need for special equipment to transport the crane. When working on the jobsite, outriggers are extended horizontally from the chassis then vertically to level and stabilize the crane while stationary and hoisting. Many Truck Cranes have slow-travelling capability (a few miles per hour) while suspending a load. Great care must be taken not to swing the load sideways from the direction of travel, as most anti-tipping stability then lies in the stiffness of the chassis

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

Tower Crane

major construction site. They are used to lift steel, concrete, large tools like acetylene torches and generators, and a wide variety of other building materials. Tower cranes have distinct advantages over conventional lattice boom crawlers or Truck Cranes because the boom or jib looms high above the work site. The tower cranes jib can place its load anywhere within the radius of operation without interfering with the structure over which it swings. In addition, the operator can either be

Truck Concrete Pumps

Truck mounted concrete pumps are those engineering products that are used to supply concrete to places which are difficult to reach by other heavy machines. Concrete Pumping Equipment required : concrete pump, heavy-duty pipe, hose and other accessories.

Mobile Cranes

of the cranes are mast, base, jib and motor. Stationary cranes are fixed whereas mobile cranes are those cranes which are mounted on trucks, trailers, or other engineering vehicles. Mobile cranes can be classified into four major categories: (1) Truck Crane; (2) crawler crane, (3) rough-terrain crane; and (4) all-terrain crane. These are explained briefly in the following paragraphs.
