Port Crane Supplier Heavy-Duty Floor Mounted Jib Crane

Product Specification

What is Heavy Duty Port Crane?

A heavy-duty rail-mounted harbor portal crane (also designed around floor mounted jib crane and heavy pedestal crane structural principles) is a heavy-duty material handling solution mounted on ground rails or structural foundation bases at port terminals.

• Working Principle: The crane combines a 360-degree continuous slewing mechanism (1.5 R/min), a variable luffing system (30–50 m/min), and an adjustable-speed hoist to cover working radii from 8.5m up to 50m.

• Main Structure: Built upon a heavy-duty gantry frame with rail traveling mechanisms, a slewing platform, structural lattice or box jib arms, an enclosed operator cabin, a protected machinery housing with pressure vessels, and centralized PLC electrical controls.

Key Features

• Robust Structure: Engineered with heavy-duty structural steel to support dead weights up to 45,026 kg and withstand demanding marine conditions.

• High Safety Performance: Includes integrated limit switches, overload cutoffs, hydraulic pressure vessels, emergency brakes, and storm anchoring systems rated for A5 to A8 work duties.

• Precise Load Control: Driven by advanced PLC systems and variable-speed hoisting for accurate load positioning across large radii up to 50m.

• Easy Maintenance: Ergonomic machinery room layouts with accessible bearings, motors, and gearboxes allow efficient routine servicing.

• Long Service Life: Utilizes corrosion-resistant marine coatings and heavy-duty structural members for continuous outdoor operation.

• Energy Efficiency: Optimized drive motors and efficient luffing mechanisms reduce power consumption during repeated heavy lifting cycles.

Applications

• Harbors & Ports: Designed for dockside breakbulk cargo transfers, heavy container lifting, and rail-to-ship freight distribution.

• Shipyards: Essential for positioning massive hull sections, steel structural beams, and heavy engine components during vessel construction.

• Steel Mills & Heavy Storage Yards: Efficiently handles raw metal materials, steel coils, plates, and scrap materials in high-capacity staging areas.

• Mining Industry: Facilitates bulk mineral offloading and heavy machinery transport at coastal or inland water terminals.

• Warehouses & Freight Logistics: Extends material movement across expansive rail tracks and outdoor storage facilities.

Frequently Asked Questions (FAQ)

Q: What is the lifting capacity and working radius of this harbor portal crane?

A: The Zehua rail-mounted harbor portal crane offers a rated loading capacity ranging from 20 to 100 tons (with standard configurations like 20 Ton, 40t crane, and 70 Ton options) and a wide working radius extending from 8.5m to 50m.

Q: Does the price include installation, commissioning, and operator training?

A: Zehua offers flexible purchasing options. We can provide direct factory equipment supply or full engineering service packages where our technical team is dispatched to your site to handle assembly guidance, commissioning, and operator safety training.

Q: Do you support customizing cranes according to my specific needs?

A: Yes, as an established crane manufacturer, Zehua fully supports custom orders. We adjust parameters such as lifting capacity, max lifting height (0–45m), working radius, rail span, work duty rating (A5–A8), and exterior paint color to match your operational site.

Q: How long does a heavy-duty port crane installation take?

A: On-site installation and testing typically take between 3 to 6 weeks, depending on foundation readiness, track alignment, weather conditions, and site availability of auxiliary lifting equipment.
