Mobile Portal Crane for Port Container & Heavy Industrial Cargo

Product Introduction

Zehua’s mobile MQ port pedestal crane is a heavy-duty material handling system engineered for port terminals, docks, and industrial yards. Designed in accordance with international FEM, DIN, and IEC standards, this versatile mobile portal crane integrates alongside dock crane units, rail mounted gantry crane lines, floor mounted jib crane installations, and shipping container gantry crane setups. Available in single-jib and four-bar linkage options, our mobile portal crane ensures reliable, smooth cargo handling.

What is Mobile MQ Port Pedestal Crane?

The Mobile MQ Port Pedestal Crane is a rail-traveling mobile portal crane built upon an elevated pedestal portal frame. It provides multi-purpose material handling across marine docks, container yards, and metallurgical logistics zones.

• Working Principle: Driven along ground-level tracks, this mobile portal crane utilizes a 360-degree slewing mechanism, variable-speed luffing, and motor-driven hoisting to transfer cargo between ships, railcars, and trucks across lifting heights up to 45 meters.

• Jib Structural Options:

  • Single-Jib Mobile Portal Crane: Features a simplified structural design with reduced deadweight and high strength, serving as a cost-effective choice for general freight and breakbulk lifting.

  • Four-Bar Linkage Mobile Portal Crane: Uses a combined lever arm mechanism that keeps cargo moving horizontally during luffing. This minimizes elevation shifts, prevents load sway, and lowers motor power consumption during continuous heavy duty.

• Core Assemblies: Constructed with a high-strength gantry portal frame, slewing turntable, lattice or box jib boom, enclosed operator cabin, and a machinery room housing Schneider electrical components, PLC, gearboxes, motors, pressure vessels, and pumps.

Key Features

• Robust Structure: High-strength steel portal frame rated for A4 work duty and maximum wheel loads of 180–300 kN, supporting deadweights up to 30,000 kg.

• High Safety Performance: Equipped with overload limit switches, storm rail clamps, emergency stops, pressure vessel safety valves, and anti-collision monitoring.

• Precise Load Control: Powered by Schneider electrical systems and PLC automation for micro-speed positioning of heavy loads.

• Easy Maintenance: Ergonomic machinery deck layout with accessible gearboxes, pumps, motors, and centralized lubrication points.

• Long Service Life: Applied with marine-grade anti-corrosion coatings and durable gear trains built to operate reliably in temperatures from 20°C to 40°C.

• Energy Efficiency: Four-bar linkage luffing minimizes vertical load displacement, reducing overall electrical power usage during continuous operation.

Technical Specifications

Applications

• Ports & Docks: Handles container transfers, breakbulk offloading, and heavy equipment loading along quay runways.

• Steel Mills & Metallurgy Fields: Moves heavy steel slabs, coils, billets, and raw scrap metal under demanding outdoor conditions.

• Shipyards: Supports hull block positioning, heavy steel plate handling, and vessel repairs along drydocks.

• Manufacturing Plants: Transports heavy machinery, large castings, and pre-fabricated structural modules.

• Warehouses & Logistics Hubs: Connects rail sidings with open storage yards to accelerate heavy inventory distribution.

• Power Plants & Mining Industry: Offloads massive turbines, industrial boilers, generators, and bulk minerals at waterfront terminals.

Frequently Asked Questions (FAQ)

Q: What lifting capacities are available for a Zehua mobile portal crane?

A: Zehua manufactures mobile portal crane units with rated lifting capacities ranging from 10 tons to 100 tons, including standard 25t, 35t, and 40t models tailored for port, dock, and metallurgical field operations.

Q: How does a single-jib mobile portal crane compare to a four-bar linkage mobile portal crane?

A: Single-jib mobile portal crane models offer a simpler structure, lighter deadweight, and high cost-efficiency. Four-bar linkage mobile portal crane models maintain a horizontal cargo trajectory during luffing, minimizing height fluctuations and energy usage during continuous heavy duty.

Q: Does Zehua dispatch engineers overseas for installation and after-sales service?

A: Yes. As a direct crane manufacturer, Zehua provides comprehensive technical support. Our qualified engineers are available to service machinery overseas, assisting with assembly guidance, commissioning, and operator training.

Q: Can Zehua customize the mobile portal crane to match our existing track and power supply?

A: Yes, we provide full OEM customization. We can adjust the wheel load (180–300 kN), rail gauge, boom reach, lifting height (up to 45m), and electrical setup to integrate smoothly into your terminal infrastructure.
