Double Trolley Overhead Crane

Double trolley overhead crane is a double girder overhead crane equipped with two trolleys, which can work simultaneously or separately. They are mainly used to lift long and big loads or sets of loads with two long distance lifting points.

Beam: This is the Double Trolley Overhead Crane's main horizontal beam structure that spans the entire width of the facility. It usually consists of two parallel girders used to support the trolley and hoist assembly. The double-girder design improves stability and lifting capacity compared to single-girder cranes.

Trolley: A trolley is a mechanical device that runs along the length of the bridge to support the hoist and load. It is responsible for horizontal movement across the bridge.

Lifting mechanism: The hoist assembly is mounted on the trolley and is responsible for lifting and lowering the load. It usually consists of a motor, gearbox, drum, wire rope or chain, hook or other connecting device.

End truck: These are wheeled assemblies mounted at each end of the bridge to support the Double Trolley Overhead Crane structure, allowing it to move along the length of the runway track.

Runway Track: This is the track installed along the length of the facility on which the crane travels. The end truck moves along these tracks, allowing the Double Trolley Overhead Crane to be positioned as needed.

Control System: The control system includes the controls and interfaces used by the operator to control the movements of the Double Trolley Overhead Crane, such as hoisting, lowering, and traversing.

Electrical components: Includes motors, brakes, limit switches, sensors and other electrical components that contribute to Double Trolley Overhead Crane operation and safety.

Safety Features: The Double Trolley Overhead Crane is equipped with various safety features such as overload protection, emergency stop button, limit switch to prevent overtravel and anti-collision system to ensure safe operation at the workplace.

Sketch:

Greater Lifting Capacity: Double Trolley Overhead Cranes typically have a higher lifting capacity than single girder cranes. Using a double girder instead of a single girder provides additional structural support and allows the crane to lift heavier loads.

Superior stability: The double girder design provides superior stability and stiffness, especially when handling large or unbalanced loads. The increased stability reduces the risk of swaying and ensures accurate positioning of the load.

Larger spans: Thanks to their robust design, Double Trolley Overhead Cranes have larger spans. Therefore, it is suitable for large installations that require larger spans.

Flexible Load Handling: The two trolleys of the Double Trolley Crane operate independently on separate main girders, increasing the flexibility of load handling. Dual trolley cranes can be configured to lift multiple loads at the same time or perform complex operations, increasing productivity and efficiency.

Lower Maintenance Costs: While the initial investment cost may be higher, the long-term maintenance costs of twin trolley axle cranes are typically lower compared to other types of cranes. Double trolley cranes are robust and reliable, with less maintenance and less downtime.

Versatility: Double Trolley Cranes can be tailored to meet specific application requirements, including dedicated lifting attachments, variable speed controls and automation integration. This versatility makes it suitable for a wide range of industries and applications.

Safer operation: Double trolley overhead cranes are equipped with advanced safety features and controls to ensure safe operation in industrial environments. These include overload protection, anti-collision systems, emergency stop buttons and limit switches to prevent overrunning.

Efficient use of space: the double trolley overhead travelling crane uses the top space of the facility to maximum the footprint. This allows for efficient material handling and workflow to be optimised within the workspace.

Steel Mills and Metal Processing: Double trolley overhead cranes are commonly used in steel mills and metal processing facilities to move heavy steel coils, ingots, billets and other raw materials. The high lifting capacity and stability of double trolley overhead cranes make them ideal for these harsh environments.

Automotive Manufacturing: Double trolley overhead cranes are used in automotive manufacturing plants to transport and position large parts such as bodies, engines, chassis and other parts during the assembly process. The ability of double trolley overhead cranes to accurately move heavy loads is very important in this industry.

Shipbuilding and Marine Industry: Double trolley overhead cranes are used in shipyards and marine facilities to lift and move ship parts, machinery and materials. Double trolley overhead cranes play an important role in the construction, repair and maintenance of ships and offshore structures.

Construction: Double trolley overhead cranes are used in construction projects to lift and transport heavy objects such as precast concrete panels, structural steel and construction equipment. It helps to increase efficiency and productivity on construction sites.

Warehouses and logistics: Warehouses and distribution centres can use double trolley overhead cranes to efficiently move and store large or heavy objects such as pallets, containers and machinery. Double trolley overhead cranes can help you move goods quickly and accurately and optimise your warehouse operations.

Mining and quarrying: double trolley overhead cranes are used in mining and quarrying operations to transport materials such as ores, minerals and aggregates. Double trolley overhead cranes are used for loading, unloading and stacking operations in both open pit and underground mining environments.

Power Generation: In power generation and utilities, double trolley overhead cranes are used for maintenance work, moving equipment components and supporting construction projects. Helps facilitate the installation and maintenance of heavy equipment such as turbines, generators and transformers.

Aerospace industry: double trolley overhead cranes play a vital role in the aerospace industry, lifting and manoeuvring large aircraft parts, engines and fuselage sections during manufacturing, assembly and maintenance.

Heavy Equipment Manufacturing: Heavy equipment manufacturing industries such as mining equipment, construction equipment and agricultural equipment use double trolley overhead cranes to move large, bulky components throughout the manufacturing process.

The company has installed an intelligent equipment management platform, and has installed 310 sets (sets) of handling and welding robots. After the completion of the plan, there will be more than 500 sets (sets), and the equipment networking rate will reach 95%. 32 welding lines have been put into use, 50 are planned to be installed, and the automation rate of the entire product line has reached
