Its hollow internal structure allows for the arrangement of cables, electrical equipment, etc. according to requirements, making the overall layout more compact and aesthetically pleasing. The main girder undergoes precise processing and strict technological treatment, with a smooth and flat surface, ensuring the stability and reliability of the crane during operation.

(II) End Beam Section

The end beam, as a key component connecting the main girder and the traveling mechanism of the crane, is generally designed in an integral or sectional structure. The integral end beam has higher strength and stability and is suitable for occasions with high precision requirements and frequent lifting operations. The sectional end beam is convenient for transportation and on-site installation and can be flexibly combined according to the actual installation site conditions. The end beam is equipped with high-quality wheels, bearings, and buffer devices, ensuring that the crane can run smoothly on the traveling track and effectively cushioning the impact generated during starting and braking, thus prolonging the service life of the equipment.

(III) Lifting Mechanism

The lifting mechanism is the core part of the European single girder overhead crane that realizes the vertical lifting of materials. It mainly consists of an electric motor, a reducer, a drum, a brake, a hook or other load-handling devices. The electric motor selected is a high-quality, energy-efficient product that can provide stable and reliable power output. The reducer has high-precision gear transmission with high transmission efficiency and low noise. It can accurately convert the rotational speed of the electric motor into an appropriate rotational speed of the drum to achieve smooth lifting and lowering actions. The brake adopts a reliable braking principle and can quickly brake in emergency situations to ensure the safety of the lifted load. Hooks are available in various specifications according to different lifting capacities and have all undergone strict flaw detection and strength verification to ensure safe loading.

II. Performance Advantages

(I) Wide Range of Lifting Capacity

European single girder overhead cranes cover a relatively wide range of lifting capacities, from several tons to dozens of tons. They can meet the diverse needs of different enterprises in terms of the weight of materials to be hoisted in various production links. Whether it is a small parts assembly workshop or a warehouse or processing workshop that needs to lift heavier finished products or raw materials, a suitable model of European single girder overhead crane can be found.

(II) High Work Efficiency

Thanks to its advanced electrical control system and excellent mechanical transmission design, the European single girder overhead crane has relatively fast lifting speeds and traveling speeds for the trolley and the crane itself. On the condition of ensuring safety, it can quickly complete tasks such as material hoisting and loading/unloading, effectively shortening the operation cycle and improving the overall efficiency of production and logistics, thereby creating more economic benefits for enterprises.

(III) Precise and Convenient Operation

Equipped with user-friendly control handles or wireless remote control devices, operators can easily control various movements of the crane, such as lifting, lowering, traveling of the crane and the trolley, and achieve precise positioning. Some high-end European single girder overhead cranes can also be integrated with an automated control system to achieve coordinated operation with other equipment such as production lines, further enhancing the automation level and precision of material handling.

(IV) Small Footprint

Compared with traditional cranes, European single girder overhead cranes are more compact in design. Their structural form means that they occupy relatively less space inside the factory building. They can make full use of the effective height and space of the factory building without causing excessive interference to the layout of other equipment in the workshop or the passage of personnel. They are especially suitable for industrial factory environments with limited space.

(V) Energy Saving and Environmental Protection

Adopting advanced energy-saving technologies, such as the selection of high-efficiency electric motors and optimized electric drive systems, European single girder overhead cranes have low energy consumption during operation, which can effectively reduce the operating costs of enterprises. At the same time, the noise and emissions generated during their operation meet environmental protection standards, contributing to the creation of a good working environment.

(VI) Excellent Safety Performance

Equipped with multiple safety protection devices, for example, the load limiter can monitor the lifting weight in real-time to avoid overloading operations that may lead to safety accidents. The travel limiters can accurately control the traveling strokes of the crane, the trolley, and the hook, preventing dangerous situations such as derailment and topping. The emergency stop button allows operators to quickly cut off the power supply and stop the crane in case of sudden emergencies. These comprehensive safety measures comprehensively ensure the safe use of the equipment as well as the safety of personnel and materials on site.
