Product Overview: 320 Tons Overhead Crane Series

Our 320 tons overhead crane series is engineered to handle the most challenging heavy-lifting tasks, with a rated lifting capacity of 320 tons and customizable configurations to adapt to different working environments and operational requirements. Whether it is lifting molten metal in high-temperature foundries, moving large ingots in steel mills, or handling heavy equipment in industrial workshops, our 320 tons overhead crane delivers stable performance and reliable operation, effectively improving production efficiency and ensuring operational safety.

The series includes multiple types of specialized cranes, each tailored to specific industry needs: the 320 tons foundry overhead crane is designed for harsh foundry environments with high temperature, high dust and harmful gases; the 320 tons four-beam casting overhead crane adopts a four-beam structure to enhance load-bearing capacity and structural rigidity; the 320 tons metallurgy double girder overhead crane is suitable for metal smelting workshops, with excellent high-temperature resistance; the 320 tons hot metal ladle overhead crane is dedicated to lifting and transporting liquid steel ladle in steelmaking processes, ensuring safe and efficient material handling.

320 Ton Overhead Crane Core Features & Technical Advantages

1. Robust Structural Design

The 320 tons overhead crane adopts advanced structural design, with options of double-girder double-track, four-girder four-track and four-girder six-track structures. The four-girder six-track structure is especially suitable for extra large-tonnage lifting scenarios, providing superior load-bearing capacity and rigidity. The main beam is made of high-quality steel, processed by integral processing technology and secondary assembly technology to release welding stress, ensuring the precision of gauge, diagonal and span, as well as stable operation during heavy-load lifting. The trolley wheel adopts a 20-wheel arrangement, with balanced wheel pressure distribution, effectively reducing the cost of the factory steel structure.

2. Advanced Control & Drive System

All 320 tons overhead crane models are equipped with Siemens PLC and Siemens inverter for control and drive, with Profinet communication between PLC and inverter, enabling real-time detection of the working status of each station. The fully variable frequency drive (VFD) system ensures smooth operation, small starting and braking impacts, and reduces energy consumption by up to 35% compared with conventional models. The control mode supports both cab operation and wireless remote control (with a 100m range), allowing operators to choose the most convenient operation method according to the working scenario.

3. Comprehensive Safety Protection

Safety is the top priority of our 320 tons overhead crane. The hoisting mechanism adopts a redundant system design to ensure the safety and reliability of lifting liquid metal or heavy loads. A complete safety monitoring system is installed, including overload protection devices, limit switches, tilt sensors and real-time monitoring cameras, which can detect abnormal situations in time and stop the operation automatically to avoid accidents. The crane is also equipped with safety brakes, zero-speed hover function and anti-sway technology, further ensuring the safety of personnel and equipment during operation. It is suitable for ambient temperatures ranging from -10°C to +50°C, with IP55 protection level, effectively resisting dust and water damage.

4. Intelligent & Customizable Configuration

The 320 tons overhead crane supports intelligent upgrades, including wireless transmission, electronic scales for real-time weight monitoring of loads, and integration with industrial internet platforms to realize full-life cycle management of the crane. The mother-child trolley configuration can realize unmanned automatic ladle hanging, saving labor costs and improving work efficiency. We also provide customized services according to customer needs, including span (10-40m), lifting height, working class (FEM: 4m, ISO: M7; A7-A8), and additional accessories such as electromagnets, grapples and spreader beams.
