Introduction
Overhead travelling cranes are machines that are used for lifting heavy loads and moving them horizontally across a workspace. They are commonly used in industries, warehouses, and construction sites. In this article, we will discuss the different aspects of an overhead travelling crane, its types, uses, and advantages.
What is an Overhead Travelling Crane?
An overhead travelling crane is a type of crane that operates on an elevated runway system. It consists of a bridge that travels across the runway and is supported by a pair of end trucks. The bridge is equipped with a hoist, which is used to lift and move objects. The hoist can be operated manually, electrically, or pneumatically.
Types of Overhead Travelling Crane
There are various types of overhead travelling crane available in the market. Some of the most commonly used types are:
- Single Girder Overhead Travelling Crane
- Double Girder Overhead Travelling Crane
- Gantry Crane
- Jib Crane
- Monorail Crane
Single Girder Overhead Travelling Crane
A single girder overhead travelling crane is the most commonly used overhead crane. As the name suggests, it has a single girder that is attached to the runway beams. It is used for light to medium-duty applications and has a lifting capacity of up to 20 tons.
Double Girder Overhead Travelling Crane
A double girder overhead travelling crane consists of two bridge girders that are attached to the end trucks. It is used for heavy-duty applications and has a lifting capacity of up to 500 tons. It is commonly used in industries such as steel mills and shipyards.
Gantry Crane
A gantry crane is a type of overhead crane that is supported by a gantry system. The gantry system can be either a single leg or double leg. It is used for outdoor applications such as loading and unloading cargo from ships.
Jib Crane
A jib crane is a type of overhead crane that is used for lifting and moving objects in a circular motion. It consists of a horizontal beam that is attached to a vertical post. The post is either mounted on the floor or a wall. It is used for light-duty applications and has a lifting capacity of up to 5 tons.
Monorail Crane
A monorail crane is a type of overhead crane that operates on a single runway. It is used for moving objects in a straight line. It has a lifting capacity of up to 10 tons and is commonly used in assembly lines and warehouses.
