Introduction to Mobile Portal Cranes

Definition and Purpose

Mobile portal cranes are versatile, heavy-duty lifting solutions designed for various cargo handling tasks in ports, terminals, and other industrial settings. They are characterized by their ability to move along a track or on wheels, providing a wide range of motion and flexibility.

Types of Mobile Portal Cranes

• Mobile Harbor Cranes: These cranes are specifically designed for port operations, handling containers, general cargo, project cargo, and bulk cargo[1][5].
• Portable Gantry Cranes: These are lighter, more compact cranes used for smaller-scale lifting operations and can be easily assembled and disassembled[2][3].

Key Features and Specifications

Lifting Capacities

Mobile portal cranes can have lifting capacities ranging from a few tons to over 100 tons. For example, the ESP.7 mobile harbor crane can lift up to 125 tons, while portable gantry cranes may have capacities up to 11,000 pounds (approximately 5 tons)[1][3].

Working Radii and Heights

The working radius of these cranes can vary significantly. Mobile harbor cranes can have a maximum radius of up to 51 meters, while portable gantry cranes typically have shorter spans, often up to 15-20 meters[1][3].

Traveling and Hoisting Speeds

Mobile harbor cranes can travel at speeds of up to 80 meters per minute and hoist at speeds of up to 120 meters per minute. Portable gantry cranes are generally slower but still offer efficient movement and lifting capabilities[1][3].

Chassis and Proping Base

Mobile portal cranes often have a robust chassis with multiple axles for stability. The propping base ensures the crane remains stable during operations, with dimensions that can vary depending on the crane model[1].

Applications

Container Handling

Mobile harbor cranes are optimized for loading and unloading fully laden containers from post-Panamax class vessels. They can perform single-lift operations up to the 16th row and twin-lift operations up to the 12th row[1].

General Cargo Handling

These cranes are designed for fast and efficient handling of all types of general cargo, with powerful lifting capacities and high-speed operations[1].

Project Cargo Handling

For precise handling of bulky and heavy project cargo, mobile harbor cranes offer high lifting capacities at shorter radii, ensuring safe and precise operations[1].

Bulk Cargo Handling

Mobile harbor cranes are also used for high-performance bulk handling on large vessels, with specific grab load curves for different classifications[1].

Technical and Design Aspects

Pedestals and Mounting Options

Mobile harbor cranes can be mounted on pedestals directly on the terminal floor, which is particularly useful for terminals with limited quay area[1].

Customization and Configurability

Portable gantry cranes, such as the PORTA GANTRY, offer high customization with various A-frame height configurations and beam lengths available to meet specific needs[3].

Safety and Compliance

OSHA and ANSI Compliance

Portable gantry cranes, like the PORTA GANTRY, are designed to be OSHA and ANSI compliant, ensuring safety standards are met for goods and personnel lifting, as well as fall protection applications[3].

Fall Protection Features

These cranes often include features for fall protection, such as overhead anchor points, and can support multiple users for fall protection applications[3].
