Cranes are widely used in a number of industries including transportation, construction, and manufacturing for loading and unloading of heavy equipment. Cranes are operated through the use of one or more simple machines that can create mechanical advantage and facilitate the lifting of loads that cannot be lifted with ordinary human efforts. Generally, cranes appear in two broad categories- overhead cranes and jib cranes with each type being used for specific purposes and tasks.
Overhead cranes are commonly used in industrial settings. While they are typically used for maintenance applications, they can also be used in manufacturing processes, the success of which typically depends on operational efficiency and minimization of downtime. Overhead cranes have multiple functionalities and applications and they come in various forms including top running cranes, double girder cranes, and under hung bridge cranes.
Top running bridge cranes are used to handle heavy loads and when materials need to be transported at high running speeds. Double girder cranes are used in lifting operations that are conducted over moderate spans. The trolleys of double girder bridge cranes operate on rails on the crane girders. For lifting operations that are conducted in limited spaces, low head room double girder cranes are an option.
Under hung bridge cranes are commonly used for operations that involve the transportation of lighter materials. They provide a greater hook cover and clearance in comparison to top running cranes. Overhead cranes are normally operated by electric power systems.
Jib cranes are typically used in industrial sites and on military vessels. A jib crane features a horizontal jib that supports a movable hoist and is attached to a wall or a pillar that is fixed to the floor. The jib can be adjusted to swing through an arc so as to support a lateral movement or it can be fixed too. Jib cranes can typically lift 1/4 ton to 5 tonnes with their outreach stretching from a 500mm to 8 meters. Jib cranes are often used to transport materials from one floor to the other and they are suitable for use in small factories or industrial settings.
Jib Cranes are far more cost effective solutions with prices from under £1000 as opposed to overhead systems where prices start at several thousand pounds! Jib's are also considerably easier to install, maintain and operate.
Whichever system you decide is most suitable for you, we recommend talking to one of our experienced professional crane engineers who can guide you through the process and make essential suggestions that can further optimise efficiency when lifting heavy loads.
End Note: While you can decrease health and safety risks through the use of cranes, you should definitely make sure that you invest time, money, and resources to ensure regular upkeep of your lifting equipment.
