If the equipment is outdated, proceed with the project to upgrade it to ARMQC (Auto Rail Mounted Quay Crane). Specification: • The RMQC (Rail Mounted Quay Crane), installed on the quay of the container terminal, consists of the hoist, trolley, gantry, and boom. Each motion is driven by vector inverters, and power for these drives is supplied through an ALM (DC converter). The control system is based on a Siemens S7-1500 PLC, along with various auxiliary devices and components. - Rated Load: Single spreader: 50 tons, Twin spreader: 65 tons - Speed: Hoist 90 m/min (with load), 180 m/min (without load), Trolley 300 m/min, Gantry 45 m/min, Boom: 5 min - Motor inverter and PLC maker: Siemens, ABB • To upgrade the automation of the RMQC, hardware components such as the PLC system, main drive system, operator cabin, and other control panels will be modernized. Additionally, control technologies related to crane safety—such as normal stop, emergency stop, brake control, and output regulation—will be upgraded to meet the latest standards. • Operator Console: The crane’s local operator cabin and wireless remote controllers will be upgraded. Recently, to improve the working environment for crane operators, reduce fatigue, and prevent safety incidents, remote operator consoles have been installed in remote operation rooms. These systems utilize ultra-high-speed, high-definition cameras and 5G communications technology to enable remote crane operation. • Automatic Operation: In automatic operation, job instructions are issued from the Terminal Operation System (TOS) and received by the Remote Manager. The Remote Manager then relays these commands to the designated crane. The instructions include details such as crane ID, operation type (loading or unloading), target position, and container information. Upon completion of the task, the crane reports the completion status to the Remote Manager, who then updates the TOS and awaits the next job. • Crane Specification Requirements for Automatic Operation: To enable automatic operation, the system incorporates technologies such as position-detecting encoders, 3D laser scanners, GPS, and cameras. These devices work together to support precise and efficient crane automation. - APIS (Automatic Position Indication System) - SPSS (Stack Profile Scanning System) - SPCS (Spreader Position Control System) - CNRS (Container Number Recognition System) - CAS (Chassis Alignment System) - CLPS (Chassis Lift Prevention System) - LCMS, RCMS (Crang Monitoring System) - TOS, Remote Manager Domestic Track Records Main Client HMM PCTC Sunkwang Overseas Track Records Client (Country) Singapore Hyosung Supplier Information • SEAH S.A.

Blade types include airfoil or flat blades, with parallel or opposed blade operation, depending on airflow requirements. It is available in various sizes and configurations, suitable for low to high-pressure systems. The damper can be equipped with electric or pneumatic actuators, and offers options for leakage class ratings, low-pressure drop, and seamless integration with HVAC automation systems. Product Description: This damper is activated by heat during a fire event. When the temperature rises and reaches the melting point of the fusible link (UL Listed 165°F), the damper blade drops like a curtain due to the force of a stainless steel spring and the blade’s self-weight. This design enables rapid fire compartmentalization in air duct systems. The damper is tested and certified in accordance with UL 555, the standard for fire dampers, which evaluates closure reliability, operation during elevated temperatures, dynamic airflow conditions, up to 3 hours of fire resistance. The FD-EL series provides dependable protection in both static and dynamic systems. Specification: The FD-EL and SD-EL series dampers are UL 555 and UL 555S certified, with 3-hour fire resistance and low smoke leakage performance. Frames and blades are made of galvanized or stainless steel, and are closed using a stainless steel spring and gravity drop. FD-EL uses a 165°F UL-listed fusible link, and SD-EL includes an electric thermal link activated by smoke or heat. Installation is possible both horizontally and vertically, and smoke dampers include a manual reset handle. All models comply with NFPA 90A, 80, and 105 standards.
