A roof crane is a type of crane that is installed on the roof of a building. This type of crane is used to move cargo in a closed environment. Overhead cranes are commonly used to move heavy loads in factories and warehouses.
The overhead crane consists of two main parts:
Bridge: The bridge is a metal structure that holds the crane inside the building. The bridge usually consists of two parallel rails on which the crane moves.
Hoist: A hoist is a system that lifts a load from the ground and allows it to move at a height. The hoist usually consists of a winch and a cable.
Overhead cranes are divided into two main types:
Single bridge: This type of crane has one bridge that moves along the roof.
Two bridges: This type of crane has two bridges that move along the roof.
Its advantages:
Moving heavy loads
Ability to move the load at height
Occupying little space
Its disadvantages:
Relatively high cost
Requires specialized installation
The applications of overhead cranes are:
Cargo handling in factories
Cargo handling in warehouses
Cargo handling in workshops
Load transfer in large structures
The right choice is made according to various factors such as the type of activity, load weight and budget.
It is better to know: arm crane
Parts used in overhead cranes
Here are some of the main parts used in an overhead crane:
Crane bridge: The crane bridge is the main structure of the crane that carries the carriage and hoist. The crane bridge can be single bridge or double bridge.
Crane carriage: The crane carriage is the structure that carries the hoist. The crane carriage can be a single carriage or two carriages.
Crane Hoist: The crane hoist is the structure that carries the hook. The crane lift can be in the form of a towing wire or a chain.
Crane coil: Crane coil is a structure on which tow wire or lifting chain is placed.
Crane engine: The crane engine supplies the power required to move the bridge, carriage and lift.
Crane gearbox: The crane gearbox reduces the speed of the engine so that it can lift the load safely.
Towing wire or crane chain: Towing wire or crane chain is used to lift and lower the load.
Crane coil: Crane coil is a structure on which tow wire or lifting chain is placed.
Crane hook: Crane hook is used to hold the load.
Crane control system: The crane control system is used to control the movement of the bridge, carriage and lift.
In addition to these main parts, the overhead crane may also have other parts, such as:
Power supply system: The power supply system is used to supply the energy needed by the crane.
Braking system: Braking system is used to prevent unwanted movement of the crane.
Safety System: The safety system is used to protect the operator and the load from damage.
Choosing the right parts for the overhead crane is very important. Parts must be made of quality materials and properly installed and maintained
