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

Gantry crane

Long popular in Europe, gantry cranes have become 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.

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

Bridge Crane

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 precise hook positioning and gentle load placement. Double girder cranes typically provide better hook height, but single girder cranes offer other advantages depending on your application.

EOT Crane

The most adaptable and the most widely used type of power driven crane for indoor service is undoubtedly the three motion Electric Overhead Travelling Crane (EOT crane). It serves a larger area of floor space within its own travelling restrictions than any other permanent type hoisting arrangement. As the name implies, this type of crane is provided with movement above the floor

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

Gantry Crane

Gantry cranes are those cranes which are generally used for moving heavy loads. They are a common 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.

In order to constitute a crane so that the Regulations will apply, the machine must have a jib or other structural member above ground level (for example the horizontal part of an Overhead travelling crane), beneath which loads can be controllably raised or lowered and also moved horizontally by movement of the jib or structural member. In addition, the load must also be suspended from a hook or other similar securing device
