Product Beschrijving

The Portal Boom Crane is a heavy-duty lifting device featuring a portal frame base, offering robust stability and flexible rotating boom functionality. It is equipped with lifting, rotating, boom extension, and travel capabilities, specifically designed for applications requiring precise lifting over a wide range, with a maximum lifting capacity of 300 tons. It is primarily used in applications such as port container handling, shipyard section lifting, hydroelectric dam construction, and railway logistics transshipment. Its gantry structure allows vehicles to pass through, enabling efficient collaborative operations, making it a core material handling solution in the heavy industrial sector.

portal crane parts​

Portal Crane mainly consists of a metal structure, hoisting mechanism, rotating mechanism, boom adjustment mechanism, traveling mechanism, boom system, operator cab, and electrical system. Below are the functional characteristics of each component:

• Metal Structure: Includes the gantry frame and upper rotating platform, providing overall support and stability.
• Hoisting Mechanism: Responsible for vertical lifting of cargo, typically equipped with a winch and steel wire rope, featuring multi-speed adjustment functionality.
• Rotation mechanism: Enables the upper part of the crane to rotate 360 degrees, using large bearings or a rotating column structure to ensure smooth operation.
• Boom adjustment mechanism: Adjusts the boom angle, using a horizontal boom adjustment system to ensure the load moves along a trajectory close to horizontal.
• Travel mechanism: Drives the crane along the track, typically comprising a motor, wheels, and a braking system.
• Boom system: Includes single booms or combined booms to accommodate different working radii and load capacities.
• Operator cab: Equipped with a control panel and viewing windows to ensure precise control of crane operations by the operator.
• Electrical system: Includes PLC control, safety devices (such as a moment limiter), and a power supply system to ensure operational safety and efficiency.

Voordelen

• Wide coverage: Gantry structure + rotating boom design enables 360° rotation and wide-area coverage, suitable for open sites such as ports and shipyards.
• High load capacity: Maximum lifting capacity of over 300 tons, meeting the needs of large component lifting.
• Precise positioning: Equipped with variable frequency speed control and PLC control systems, lifting positioning accuracy reaches ±5mm, suitable for precision assembly scenarios.
• High-efficiency accessibility: Vehicles or tracks can pass beneath the gantry, enabling simultaneous “lifting + transportation” operations to enhance logistics efficiency.
• Strong environmental adaptability: Features wind-resistant anchoring devices and corrosion-resistant coatings, designed to withstand harsh port conditions such as high salt fog and dust.
• Modular maintenance: Key components (such as slewing bearings and steel wires) feature quick-release designs to minimize maintenance downtime.

Types of Portal Boom Crane

Based on structural characteristics, Portal Boom Cranes are primarily categorized into the following three types:

Full Portal Crane: Both sides of the portal frame are supported by ground tracks, forming a complete portal structure, suitable for standard track layouts. Primarily used in ports, yards, and other locations requiring large spans and high stability for loading and unloading operations.

Semi-Portal Crane: One side of the legs is supported on ground tracks, while the other side is supported on elevated tracks or buildings, making it suitable for sites with limited space. It is commonly used in railway freight yards, shipyard outfitting areas, and other environments with single-side restrictions.

Tower-Type Portal Crane: The rotating section is connected to the portal frame via columns, featuring a compact structure. It is suitable for terminals requiring coordinated operations by multiple cranes. It is primarily used in container terminals and other locations requiring high-density crane layouts.
