LD type overhead travelling crane, also known as single girder overhead crane, is a type of crane that is commonly used in factories, workshops, and warehouses for lifting and transporting heavy loads. The main components of this crane include a single girder, end trucks, hoist trolley, and a control system.
The LD type single girder overhead travelling crane is typically used in applications where the load capacity is less than 20 tons and the span is less than 31.5 meters. It is commonly used in workshops, warehouses, and other industrial settings where materials need to be lifted and transported.
The LD type single girder overhead travelling crane is known for its compact design, high efficiency, and easy operation. It is also relatively easy to install and maintain, making it a popular choice for many industrial applications.
Features about LD type single girder overhead travelling cranes:
Single girder: The single girder is the main structural element of this crane, responsible for supporting the load. It is typically made from steel and is designed to withstand the stress and bending moments caused by the load.
End trucks: These are attached to either end of the single girder and allow the crane to travel along a runway, which is typically a pair of parallel beams. The end trucks contain the wheels and motors that enable the crane to move.
Hoist trolley: The hoist trolley is mounted on the single girder and moves along its length. This component is responsible for lifting and lowering the load. The hoist trolley typically contains a motor, gearbox, and a drum or pulley system to lift the load.
Control system: The control system of an LD type overhead travelling crane can be operated from a pendant control station or a remote control. This system allows the operator to control the movement of the crane, as well as the hoisting and lowering of the load.
Advantages of LD type overhead travelling cranes include:
Cost-effective: They are generally less expensive than double girder cranes due to their simpler design and fewer components.
Easy installation and maintenance: The single girder design simplifies installation, and maintenance is generally easier as there are fewer components to inspect and maintain.
Versatility: These cranes can be used for a wide range of applications, including manufacturing, assembly, and maintenance tasks.
