Double girder overhead crane is a widely used lifting equipment in modern industry. It is mainly composed of two main beams, electric trolley, end beam, electrical control system and other safety devices. According to different working levels, the crane can be divided into multiple working levels from A3 to A7, and the operation methods include multiple options such as pendant control, remote control and cabin operation.
Advantages:
- Sturdy structure: The double-beam design provides greater load-bearing capacity and stability, and is suitable for the handling of heavy materials.
- High efficiency performance: Higher lifting speed and running speed improve work efficiency.
- Flexible operation: Provides multiple operation modes, such as bracket operation, remote control and cab operation, to meet different operation requirements.
- Safe and reliable: Equipped with complete safety devices to ensure safety during operation.
Application:
Double girder overhead crane is widely used in workshops, maintenance workshops, warehouses, shipyards, docks, steel mills, military and other places. The working environment temperature range is -20℃ to +40℃. It is forbidden to use in flammable, explosive and highly corrosive environments. When equipped with an electric grab as a sling, it can be used for loading and unloading and transporting bulk materials. It is not suitable to work in an environment with explosion and fire hazards, nor in places with high humidity and full of acid and alkali gases. It cannot be used to transport molten metal, toxic substances and flammable and explosive items.
Introduction to the components of double-beam bridge crane
Mechanical parts
- Main beam: It adopts welded box beam, which meets the national standard for camber and is made of high-quality carbon steel Q235B or Q345B (similar to Fe37 or Fe52). The main weld adopts submerged arc automatic welding and non-destructive testing to ensure the welding quality.
- Trolley: It consists of motor, reducer, brake, coupling, wheel and roller. The brake system uses asbestos-free brake pads and brake blocks, which are safe and reliable to install.
- Reducer: It adopts hard tooth surface design, compact and durable structure.
- End beam: It is equipped with track buffer and track gap device to enhance safety and stability.
- Protection level: The overall protection level of the crane is IP54 or IP44, and the insulation level is F level to ensure electrical safety.
- Braking system: The braking is effective and has a long service life to ensure stable operation of the equipment.
Protective devices
- Rainproof device: Outdoor cranes are equipped with lifting mechanisms, electrical control boxes and rainproof devices to ensure the normal operation of the equipment in bad weather.
- Safety limit device: Set up trolley travel limit devices and anti-collision devices to increase operational safety.
- Alarm system: Equipped with sound and light alarm devices to improve safety warning effects.
- Protective facilities: Set up platforms, covers, protective covers and barriers to protect the safety of operators and equipment.
