Tower Crane Reliability in High-Rise Construction

Manitowoc and Orbi Group deploy Potain tower cranes to ensure continuous lifting operations for the Central Park Towers hotel project in Tbilisi.  www.manitowoc.com Two Potain MCT 275 tower cranes have been deployed on a large-scale hotel development in Tbilisi, supporting continuous lifting operations with sustained availability across a multi-phase construction project. Context of the Cooperation The Central Park Towers development in Tbilisi is a multi-structure, high-rise project combining hospitality and mixed-use infrastructure. The project is developed and constructed by Orbi Group, with hotel operations managed by Radisson Blu. Given the scale and phasing of the construction, maintaining uninterrupted lifting capacity is critical for coordinating material flow, workforce scheduling, and structural progression. This requires not only robust lifting equipment but also continuous technical support and maintenance services. The cooperation between Manitowoc, through its Potain crane division, and the project stakeholders addresses these requirements by combining equipment reliability with long-term service support. Technical Solution and Responsibilities The lifting solution is based on two Potain MCT 275 topless tower cranes configured for high-rise construction. Manitowoc (Potain) provides: Tower crane equipment (MCT 275, 10 t configuration) Erection and commissioning services Ongoing maintenance, inspections, and spare parts supply Operator and maintenance training Orbi Group is responsible for: Site operations and construction management Integration of crane operations within project workflows The cranes were initially installed in a freestanding configuration and later climbed to a final working height of 150 m. Jib configurations of 45 m and 50 m enable load distribution across the construction site. The MCT 275 model supports: Maximum lifting capacity of 10 t End-of-jib capacity up to 2.3 t Configurable jib lengths from 30 m to 70 m This configuration enables efficient handling of materials across wide and complex site layouts, supporting synchronized operations in construction engineering environments. Deployment and Implementation The cranes have been in continuous operation for over three years, supporting multiple construction phases. Implementation included: Initial erection and commissioning Progressive climbing aligned with building height Integration into daily lifting schedules Regular certified inspections and preventive maintenance Manitowoc’s service team provides on-site and remote support, ensuring operational continuity and rapid response to technical requirements. Applications and Use Cases Primary applications include: Lifting structural components for high-rise construction Material handling across multiple building zones Support for phased construction activities The cranes enable coordinated logistics and stable workflow management, particularly in dense urban construction environments. Results and Expected Impact The deployment has achieved: Zero unplanned downtime over three years of operation Consistent lifting performance across all project phases Reduced risk of construction delays due to equipment failure These outcomes result from the combination of equipment design, preventive maintenance, and continuous technical support. The cooperation demonstrates how integrated equipment and service strategies can enhance reliability and operational efficiency in large-scale construction projects.
