MECHANICAL Electrical Instrumentation & Control Chemical Engineering Service & Maintenance RMQC & ARMQC Product Description: The control panels installed in the RMQC (Rail Mounted Quay Crane), which is used as a port crane. If the equipment is outdated, proceed with the project to upgrade it to ARMQC (Auto Rail Mounted Quay Crane).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.
