Introduction to the European Electric Single-Girder Suspension Crane
The LX Type European Single-Girder Suspension Crane is also referred to as the LX Type European Electric Single-Girder Suspension Crane, LX Type European Suspension Crane, LX Type European Suspension Single-Girder Crane, LX Type Electric Single-Girder Suspension European Crane, or LX Type European Standard Electric Single-Girder Suspension Crane. This model integrates the lightweight, compact design philosophy of European Standard Cranes with suspension-type installation, offering advantages such as low dead weight, reduced wheel load, and minimal space occupancy.
The crane rail of the LX Type European Suspension Crane is fixed to the bottom chord of the factory roof truss using dedicated connectors, allowing the entire crane to operate in a suspended manner. Since no support columns are required for the crane rail, the entire workshop floor area can be utilized for production equipment layout or warehouse stacking. With an optional extending cantilever, the trolley's travel range can extend beyond the crane span; when fitted with interlocking devices, the trolley can transfer directly between the suspension main girder and the monorail without unloading, enabling continuous cross-area material transport.
Kelude Heavy Industry's LX Type European series covers lifting capacities from 0.5t to 20t and spans from 2m to 20m, with full-size non-standard customization available. The product has been widely applied in industries including machining, automotive assembly, electronics manufacturing, and warehousing and logistics, with over 300 units delivered to date.

Structural Features
1. Lightweight Design
Comment from Kelude Heavy Industry's Chief Technical Officer
"The LX Type European Electric Single-Girder Suspension Crane is our high-volume product for the domestic market, offering outstanding cost-performance. Take the project supplying 12 units of LX3-10.5 to an automotive parts manufacturer as an example: the customer's workshop height was only 8m, and a traditional LD Type required 2.6m of headroom, leaving an effective lifting height of just 4.8m. After switching to the LX European design, headroom dropped to 1.9m, increasing the usable lifting height to 5.7m (+19%), much to the customer's satisfaction. The dead weight of the entire crane is approximately 28% lighter than a traditional LD Type, allowing installation on older factory roof structures without reinforcement."
— Mr. Wang, Technical Department, Kelude Heavy Industry
Through modular design using specialized crane software and European advanced technology, the hoist, end carriages, and main girder all adopt optimized structural solutions, resulting in a dead weight far lower than traditional cranes. This translates to lower wheel loads on the crane rail, reduced demands on the factory building structure, broader applicability, and significant savings in factory construction costs.
2. Compact Dimensions
The LX Type European Suspension Crane makes highly efficient use of factory space. The minimum distance from the hook to the side walls is reduced, and headroom is kept low, maximizing the effective working space within existing buildings and offering greater flexibility in plant layout planning. New facilities can be designed smaller and more functionally complete.
3. High Performance
Equipped with Variable Frequency Speed Control, the crane operates smoothly, minimizing load swing for faster and more precise positioning during hoisting. Variable Frequency Speed Control also reduces friction and mechanical stress between the crane and the factory structure, extending the overall service life of the equipment.
4. Easy Operation
Standard configuration includes pendant control (IP65 Protection Rating, 500,000 electrical cycles), with a Wireless Remote Control System available as an option. Radio control options include handheld transmitters and joystick-style transmitters, providing the optimal control solution for demanding and complex operating environments.
5. High Safety Factor
Equipped with over a dozen protective measures including overheat protection, Overload Protection, and Phase Sequence Protection, ensuring safe crane operation. The drum diameter of the hoisting mechanism is more than double that of traditional products, minimizing the wire rope deflection angle and effectively reducing tensile stress and wear on the wire rope. The high-performance hoisting motor delivers greater power while offering excellent cooling characteristics for continuous duty operation. Large-capacity hoisting units feature two hoisting motors, and the hoist incorporates a dustproof design and an auto-adjusting braking system. A Double Brake can be provided for special requirements.
6. Low Operating & Maintenance Costs
Designed with a green philosophy, the crane consumes minimal power and electricity. Its high reliability results in an extremely low failure rate under proper usage conditions, minimizing production losses due to equipment downtime and reducing maintenance expenses.

FAQ
Q: What is the maximum Lifting Capacity of the LX Type European Electric Single-Girder Suspension Crane?
A: The LX Type European standard series covers 0.5t to 20t. The 0.5~5t range comprises the most common specifications. 10t and 16t models require a specific load verification of the factory's suspension point capacity, and the 20t model requires a reinforced main girder configuration. For higher capacities (above 20t), we recommend considering the LDX Type or the QD Type double girder solution. Kelude Heavy Industry offers free selection consultation services.
Q: Can this model be used for retrofitting old factory buildings?
A: Absolutely. The LX Type European Suspension Crane mounts directly onto the existing roof structure without the need for additional columns. Its dead weight is 25~35% lighter than a traditional LD Type, significantly reducing wheel loads, meaning most older factory roof structures can accommodate it without reinforcement. Kelude Heavy Industry provides free Site Survey and roof structure load capacity verification services, with a retrofit plan delivered within 15 working days.
Q: Can the Lifting Speed be customized?
A: Yes. The standard configuration is Two-Speed (5/0.83m/min), with an optional Variable Frequency Stepless control (0.5~8m/min). The Variable Frequency configuration offers a 1:10 speed ratio, adjustable acceleration/deceleration (0.15~0.5m/s²), and is suitable for hoisting applications requiring precise positioning. The Variable Frequency configuration adds approximately 8~12% to the cost compared to the Two-Speed configuration.
Q: Is registration as special equipment required?
A: LX-type European suspension cranes with a lifting capacity of ≥3t are classified as special equipment and must be registered for use and undergo periodic inspection. Kelude Heavy Industry provides the Factory Acceptance Test Report (FAT), Certificate of Conformity, and Type Test Report with each product, and assists customers in completing TSG installation supervision inspection. Light-duty equipment with a lifting capacity of <3t falls outside the scope of special equipment regulation.
