Crane Modernisation & Engineering Consultation

---

Proven Expertise in Crane Modernisation

Portcrane.sg delivers high-value engineering consultation focused on modernising RTG, STS, and E-RTG cranes to meet today’s demands for safety, efficiency, and regulatory compliance. We work closely with port authorities, terminal operators, and OEMs to extend asset life, reduce energy costs, and improve crane availability—without compromising operational continuity.

Our consultation services cover the full modernization lifecycle, from feasibility studies to commissioning support. We specialise in electrical, mechanical, and control system upgrades, ensuring seamless integration with existing crane structures and terminal infrastructure.

Key areas include:

• DC to AC motor replacement
• DC drive to AC drive migration
• VFD selection, tuning, and master–slave configuration
• Hoist, trolley, and gantry motion optimization
• Motor replacement and efficiency upgrades

All solutions are engineered to comply with ISO standards, FEM crane classifications, and relevant port authority technical requirements.

Portcrane.sg supports ports transitioning to E-RTG and hybrid RTG systems through advanced energy management and smart grid consultation. We optimize power distribution, regenerative braking, peak demand control, and grid interaction to reduce operational costs and support sustainability goals.

Our approach aligns with:

• ISO energy management principles
• Grid code and utility interface requirements
• Port electrification and decarbonization programs

We provide advanced condition monitoring and machine health analysis for RTG and STS cranes, enabling predictive maintenance and reduced unplanned downtime.

Services include:

• Static and dynamic vibration analysis on cranes
• RTG and STS frame monitoring and fatigue assessment
• Structural and mechanical health evaluation
• Drive, motor, and gearbox condition diagnostics

These assessments are performed in accordance with ISO vibration standards, FEM structural guidelines, and port safety regulations.

Accurate hoist calculations are critical when upgrading drives or replacing motors. Our engineers perform detailed torque, load spectrum, braking, and thermal calculations to ensure safe and compliant crane operation—especially during DC to AC conversions and high-duty STS applications.

We also support:

• Performance validation and acceptance testing
• Test kit selection and commissioning procedures
• Documentation for audits and authority approvals

Every Portcrane.sg consultation is delivered with a strong focus on:

• ISO, FEM, and local port authority compliance
• Improved safety and operational reliability
• Reduced lifecycle and energy costs
• Minimal disruption during retrofit and modernisation
