Product Description

Portal cranes are widely used in cargo loading and unloading at ports and docks, construction and installation at shipyards, and construction of large hydropower stations. Portal cranes generally adopt single-arm wire rope luffing, single-arm rack luffing or four-link arm rack luffing structure, and are equipped with hooks or grabs to load and unload cargo. The crane's rotating mechanism is installed on the machine base, and the gantry machine base is actually the load-bearing part of the crane. There is a running mechanism under the gantry machine base, which can travel on the track set on the ground. The arm and luffing mechanism of the lifting mechanism are also installed above the rotating mechanism. The four mechanisms work together to complete the installation of equipment or ship sections, or to carry out cargo loading and unloading operations.

Characteristics

  • Level Luffing Mechanism: The system that ensures the load remains level while the boom angle is adjusted;

    Boom: The angled arm or beam that can be adjusted to different angles (luffing) while maintaining the load level;

    Hoist: The mechanism used for lifting and lowering loads.

  • Gantry Frame: The main structural framework that supports the crane, consisting of two or more legs and a bridge beam.

    Trolley: The component that moves along the bridge beam and supports the hoist and load.

    Control System: Includes the controls for operating the crane, typically via a pendant, remote control, or operator cabin.

Advantages

  • 1 Precise Load Handling: Keeps the load level during luffing, which is essential for accurate positioning.
  • 2 Increased Safety: Reduces the risk of load swinging and instability.
  • 3 Efficiency: Facilitates quicker and more efficient operations by minimizing the need for additional adjustments.
  • 4 Versatility: Suitable for various applications that require precise load handling.
  • 5 Improved Operator Control: Allows for better control over the load position, enhancing operational efficiency.

Application

  • 1 Ports and Harbors: Loading and unloading ships with precision, especially useful for handling containers and bulk materials.
  • 2 Shipyards: Assembling and moving large ship components with accuracy.
  • 3 Construction Sites: Positioning heavy construction materials and equipment accurately.
  • 4 Industrial Facilities: Handling heavy machinery and materials where precise positioning is critical.
  • 5 Power Plants: Moving large components during construction and maintenance operations.
