Overhead Crane Projects

125t & 50t Overhead Cranes Delivered to Mining Project in Uzbekistan

AICRANE has successfully delivered, guided the installation of, and commissioned one 125-ton and one 50-ton double girder overhead crane for a prominent mining enterprise in Uzbekistan. Deployed during the crucial mining construction phase, these heavy-duty cranes are now fully operational, securing the safe and on-schedule installation of core mining machinery, structural assemblies, and ongoing maintenance workflows.

Project Overview: Heavy-Duty Lifting Demands in Uzbekistan’s Mining Sector

Located in a major industrial zone in Uzbekistan, this mining project is a typical heavy industrial construction site involving large-scale equipment installation and continuous lifting operations.

Heavy and oversized equipment installation: The main processing systems include large crushing and material handling equipment requiring high-capacity lifting.

Continuous lifting activities on site: Multiple installation stages required frequent lifting operations with limited idle time for cranes.

Strict construction schedule: The project followed a fixed commissioning timeline, requiring reliable and stable lifting equipment throughout the construction period.

Multi-zone construction layout: Different workshop spans were used for separate installation tasks, requiring cranes with different lifting capacities for parallel operations.

Engineering Solution: Multi-Capacity Overhead Crane Configuration

Based on the project requirements in Uzbekistan, two overhead cranes with different lifting capacities were installed in separate workshop spans to handle different lifting tasks during the construction process.

125-Ton Double Girder Overhead Crane: Heavy-Duty Lifting Operations

The 125 ton overhead crane was assigned to the most critical lifting tasks in the mining project, including:

  • Installation of large crushing and processing equipment
  • Lifting of heavy steel structural modules
  • Precise positioning of oversized mechanical assemblies

50-Ton Double Girder Overhead Crane: High-Frequency Auxiliary Support

The 50 ton overhead crane complements the main lift crane by executing daily operational and auxiliary tasks, including:

  • Medium-sized equipment installation
  • Material transportation within the workshop or construction site
  • Supporting assembly operations during main equipment installation

Delivery & Commissioning: Precision Engineering on Site

AICRANE provided a comprehensive service package for this project in Uzbekistan, extending beyond manufacturing to intensive on-site installation guidance and system commissioning.

Technical Installation Guidance

The AICRANE field service team supervised and verified the following mechanical and electrical alignments:

  • Structural Alignment: Performed geometric leveling and span verification to align the crane main girders with the runway rail system.
  • Mechanical Connections: Supervised the torque tightening of all high-strength bolts connecting the main girders to the end trucks.
  • Electrical Integration: Audited power supply cabling, busbar contacts, and control cabinet wiring to eliminate voltage-drop risks.

Commissioning and Functional Testing

For these heavy-duty cranes, a sequential testing protocol was executed to verify structural integrity and rated capacities:

  • Load Sequence Testing: Conducted standard static and dynamic load tests (including rated load and specified overload verifications) to measure girder deflection and structural recovery.
  • Travel and Alignment Controls: Calibrated Variable Frequency Drives (VFD) to ensure synchronized acceleration and deceleration for both bridge and trolley travel.
  • Safety System Verification: Tested and set upper/lower hoisting limit switches, anti-collision sensors, emergency stop circuits, and overload protection limiters.

Project Results: Driving the Project to Successful Production

The successful deployment and testing of the 125t and 50t double girder overhead cranes delivered the following direct operational results for the Uzbekistan mining project:

Stable execution of critical lifting operations: The project achieved uninterrupted lifting support during key installation stages, ensuring consistent construction progress.

Improved overall construction efficiency: Work sequencing and on-site coordination were optimized, reducing downtime between lifting and installation activities.

Reliable continuous performance: Both cranes maintained stable operation under continuous working conditions, providing dependable lifting support throughout the project execution period.
