RMG Crane vs RTG Crane: Which Is Better for Container Yard Operations?

RMG rail gantry crane and RTG tire gantry crane are the two most widely used core equipment in container yard at present. They have significant differences in operation mode, mobility, automation level and adaptation scenario. Through the comparison of core parameters, the advantages and adaptation scenarios of the two types of equipment are clearly distinguished, providing accurate reference for the selection of yard equipment.

How to Select the Right Gantry Crane for Container Yard Operations

Determine lifting capacity

Hoisting tonnage is the core basic parameter of gantry crane selection, which directly determines whether the equipment can meet the mainstream container operation requirements of the yard. At present, the mainstream operation containers in the industry include 20-ft standard containers, 40-ft standard containers and 45-ft ultra-high and ultra-long containers. The deadweight and load of containers of different specifications are quite different, so it is necessary to match the corresponding lifting capacity of equipment.

Small inland yards are mainly operated by 20ft containers, and medium and small tonnage gantry cranes can be selected. Mainstream ports and logistics yards shall give consideration to 40ft and 45ft container operations, and shall be matched with large-tonnage heavy-duty models. In high-frequency and large-scale operation scenarios, it can give priority to high-configuration equipment for double-container hoisting, complete the hoisting of two standard containers at a time, and greatly improve the operation efficiency. Certain tonnage allowance shall be reserved during type selection to avoid equipment loss caused by long-term full-load operation and ensure long-term stable operation of equipment.

Consider working span and stacking height

Operation span and stacking height directly determine the storage density and operation coverage of the yard, and are the key parameters for optimizing the layout of the yard. The operation span of the gantry crane shall match the width of the single operation area of the storage yard, so as to ensure that the equipment can completely cover the container stacking ranks, reduce the operation blind area and adapt to the overall planning and layout of the storage yard.

The stacking height shall be selected in combination with the land resources, operation requirements and safety specifications of the yard. For the yard with scarce land and pursuing high storage capacity, the model with high stacking height can be selected to maximize the vertical storage capacity. Conventional small and medium-sized storage yards can match standard stacking heights, balancing operating efficiency and equipment costs. Reasonable span and height collocation can maximize and optimize the storage layout of the yard, improve the storage capacity per unit area, and avoid space waste and excess equipment performance.

Evaluate automation features

Intelligent automation configuration is the core consideration factor of modern gantry crane selection, which directly determines the operation efficiency and labor cost of yard. The basic automation configuration includes remote control, intelligent anti-swing and automatic positioning functions, which can greatly reduce the difficulty of manual operation and improve the operation accuracy. The high-equipped intelligent model is equipped with unmanned operation, AI intelligent scheduling, real-time data monitoring, automatic fault warning and other functions, which can seamlessly connect with the intelligent yard management system.

The enterprise shall plan and select the type in combination with its own intelligent upgrading: the basic automation model can be selected for short-term routine operation to meet the demand of efficient operation. Enterprises with long-term layout of smart ports and unmanned storage yards need to give priority to fully automatic models to adapt to the future trend of intelligent and digital operation and complete the upgrading of equipment infrastructure ahead of schedule.

Check reliability and maintenance requirements

Equipment reliability and later operation and maintenance cost are the key factors affecting the long-term operating income of the yard. During model selection, it is required to check the durability of equipment structure, and give priority to equipment with high-strength anti-corrosion steel structure and high-quality core accessories to meet the long-term operation requirements of outdoor heavy load and complex working conditions and reduce the failure rate.

At the same time, attention shall be paid to the universality and availability of equipment accessories, and the models of general standardized accessories in the industry shall be preferred to facilitate rapid replacement in the later period and reduce the procurement cost of accessories. In addition, the after-sales support capability of the manufacturer is very important. Perfect after-sales operation and maintenance system, quick fault response and regular equipment maintenance service can minimize equipment downtime, ensure all-weather stable operation of the yard and reduce long-term operation cost.
