Italy stands as one of Europe's most important automotive manufacturing hubs, home to numerous world-renowned automobile manufacturers. These enterprises have extremely stringent requirements for production equipment precision, reliability, and efficiency.
This case study involves an Italian client—a large automotive parts manufacturer located in the Turin industrial district. The company specializes in precision machining of critical components such as automobile engine blocks and transmission housings.
When expanding their production line, the client needed to procure high-performance jib crane equipment for material handling, workpiece loading and unloading, and die change operations in their workshop. After rigorous technical evaluation and supplier screening, the client ultimately selected Weihua Group's jib crane product portfolio, including both pillar-mounted jib cranes and wall-traveling jib cranes.
Based on the client's workshop spatial layout and production process requirements, Weihua's technical team configured multiple pillar-mounted jib cranes for the facility. The main technical features of this crane type include:
Structural Design: The cranes feature high-strength steel structure pillars fixed to the ground through embedded anchor bolts, ensuring equipment stability and safety under full-load conditions. The jib arms are made from premium I-beam materials, precisely calculated and optimally designed to maximize working radius while ensuring load capacity. The jib arms can rotate horizontally within 360 degrees, equipped with high-precision rotation bearings for smooth operation and accurate positioning.
Lifting System: WEIHUA brand electric chain hoists are configured with rated lifting capacities of 1 ton, 500 kg, and 2 tons respectively. The hoists utilize German-imported motors and reducers, featuring low operating noise, smooth lifting, and precise positioning. The hoists are mounted on dedicated trolleys that can move horizontally along the jib arm, achieving three-dimensional material handling.
Power Supply System: Safe conductor bar power supply is adopted, with cables moving synchronously with the hoist, avoiding cable wear and safety hazards common with traditional trailing cable methods. The control box features ergonomic design with reasonably arranged operation buttons, equipped with multiple safety functions including overload protection, phase failure protection, and limit protection.
For the client's production stations arranged along workshop walls, Weihua provided wall-traveling jib crane solutions. The core features of this equipment include:
Track System: We install dedicated track beams on the workshop side walls, and the cranes travel longitudinally along the track using their traveling mechanism. This design does not occupy any floor space, making it ideal for multi-station, assembly-line production layouts. High-strength cold-formed steel with an anti-corrosion surface treatment forms the tracks, offering a service life exceeding 20 years.
Mecanismo de deslocação: The traveling mechanism adopts rack-and-pinion drive with variable frequency speed regulation technology, allowing the crane to adjust steplessly within a speed range of 0.05 to 12 meters per minute. Equipped with precision limit devices, the equipment safely stops at both ends of the track, avoiding collision accidents.
Jib Arm Design: Wall-traveling jib crane jibs can also rotate horizontally, and together with the lifting hoist, they achieve full coverage service for wall-mounted stations. The jib cross-section has been optimized for design, minimizing self-weight while ensuring strength and reducing load requirements on building structures.
Equipment arrived at the client's factory in spring 2026, and Weihua dispatched a team of senior engineers for on-site installation and commissioning services in Italy. The installation and commissioning work strictly followed these procedures:
Foundation Acceptance: First, we rechecked the position and elevation of the embedded parts and confirmed that they complied with design requirements before pillar installation. Then, we tightened all connection bolts according to the specified torque and marked them for anti-loosening verification.
Precision Adjustment: After installing the jib arm, we used levels and theodolites to precisely adjust the jib's horizontal level and rotational verticality. During no-load hoist operation, we measured resistance changes as the trolley traveled along the jib, ensuring that no abnormal sticking occurred.
Load Testing: We conducted rated load tests and 125% overload tests according to the loads specified in the contract. During testing, we monitored key indicators including pillar verticality changes, jib deflection values, and rotation braking distances—all of which complied with design specifications.
Client Training: Upon completion of installation and commissioning, Weihua engineers provided detailed theoretical and hands-on training for client operating personnel. Training covered equipment operating procedures, daily maintenance, common troubleshooting, and safety precautions. Detailed equipment operation manuals in both Chinese and Italian were provided.
The client gave high praise for Weihua equipment installation quality and commissioning performance, with acceptance passed on the first attempt. The Italian client's technical director stated that Weihua crane performance fully matched European products, while price advantages and service response speed were clearly superior.
After entering production, Weihua jib cranes undertook multiple critical tasks in the client's workshop:
Engine Block Handling: During transfers between precision machining centers, operators using Weihua jib cranes equipped with vacuum lifters can safely and quickly lift and transfer engine blocks weighing several hundred kilograms from machine tools to the next process. The entire operation requires only one operator, greatly improving work efficiency.
Die Change Operations: The client's production line requires frequent die changes. By using Weihua pillar-mounted jib cranes with dedicated lifters, operators can change a set of large die-casting dies in just 10 minutes, improving efficiency by over 40% compared to traditional methods.
Continuous Production Line Service: Wall-traveling jib cranes arranged along walls provide material supply services for assembly stations along the line. Operators can quickly lift materials from the preparation area to designated stations, eliminating conflicts with floor transport equipment and making production rhythm smoother.
Equipment Maintenance Support: Weihua Cranes also handle daily maintenance and repair operations of workshop machining equipment, such as spindle replacement and tool adjustment. The equipment's precise control capability enables maintenance personnel to accurately place heavy components in designated positions.
Overall, Weihua jib cranes improved the client's workshop material handling efficiency by over 35%, reduced labor costs by approximately 20%, and maintained equipment comprehensive availability above 99.5%.
Weihua Group's jib crane products have passed multiple international authoritative certifications, fully complying with Italian and EU market legal and regulatory requirements:
Certificação CE: All exported products bear the CE mark, indicating compliance with EU Machinery Directive (2006/42/EC) basic safety requirements and health requirements. Complete EU Declaration of Conformity and technical documentation are provided with the equipment.
