What are the primary operational advantages of a Mobile Harbour Crane (MHC) compared to rail-mounted quay cranes?

For multi-purpose ports and terminals without dedicated rail infrastructure, a Mobile Harbour Crane (MHC) offers unmatched flexibility: Zero Rail Dependency & High Mobility: Built on a multi-axle rubber-tired chassis, an MHC can drive freely across different berths, storage yards, or even move to another quay section as vessel traffic demands. Lower Capital Expenditure (CapEx): Eliminates the huge upfront civil engineering costs required for laying heavy crane rails and strengthening quay edges. Instant Multi-Cargo Adaptability: Effortlessly switches between container handling (single/twin-lift spreaders), bulk discharging (motor hydraulic or mechanical grabs), and heavy-lift breakbulk handling with a simple hook attachment.

How does the multi-axle chassis and outrigger system manage ground bearing pressure on older wharves?

Ground loading is a critical safety constraint for dockside operations:Hydrostatic Equalized Axles: During transit, the multi-wheel steerable chassis distributes the deadweight evenly across dozens of heavy-duty tires to stay within allowable quay surface axle loads.Large-Surface Outrigger Pads: During lifting operations, heavy-duty hydraulic outriggers deploy onto large steel/composite supporting pads. This spreads the working loads safely across a wide area, ensuring compliance with strict wharf load limits (e.g., keeping pressure under $\mathbf{30\text{ to }40\text{ t/m}^2}$).

What drive configurations are available, and how can shore power (E-drive) cut terminal operating costs?

MHCs feature advanced power architecture designed to minimize fuel consumption and carbon footprint:Diesel-Electric / Diesel-Hydraulic Drive: A diesel engine generator set powers electric or hydraulic motors for all main motions (hoisting, slewing, luffing, and travelling), offering high energy efficiency and precise VFD control.Plug-In Shore Power (Zero-Emission E-Drive): Equipped with an automatic cable reel, the crane can plug directly into the terminal's high-voltage shore power grid ($6.6\text{ kV}$ or $11\text{ kV}$). This slashes fuel consumption by up to 60% to 80%, drastically lowers noise levels, and reduces maintenance costs on the diesel generator.

How does the electronic anti-sway control system maintain high productivity during container handling?

To compete with dedicated STS (Ship-to-Shore) container cranes, modern MHCs integrate advanced automated assist systems:Active Anti-Sway PLC Automation: Sensors track rope angle and payload momentum in real time, automatically compensating motor speeds during slewing and luffing to damp out load sway instantly.Rotatable Tower Head & Spreader Control: Allows 360 continuous or fine-tuned angular alignment of containers, enabling operators to achieve fast, precise container positioning inside vessel cell guides even in windy conditions.

PRODUCT INTRODUCTION

The Mobile Harbour Crane (MHC) is a versatile, high-mobility cargo handling solution purpose-built for modern ports. Equipped with a rubber-tyred travelling system, it moves flexibly along the quay and turns on the spot, precisely responding to the demands of different berths. It supports the quick switching of various attachments such as hooks, grabs, and container spreaders, and is widely used for handling containers, bulk materials, general cargo, and heavy project lifts—making it an indispensable core asset for multi-purpose terminals.

FEATURES

Exceptional Mobility: The rubber-tyred undercarriage enables 360° on-the-spot turning and crab steering, allowing the crane to maneuver easily in tight spaces and relocate quickly along the quay.

Quick Spreader Change: The system allows for rapid changeover between hook, grab, and container spreader within minutes, seamlessly adapting to containers, bulk, and general cargo.

Broad Operational Capability: With a working radius of up to 64 meters and lifting capacities reaching hundreds of tons, the crane efficiently serves all major vessel classes—from barges to ultra-large container ships

Precise & Intelligent Control: Equipped with advanced AC variable frequency drives and PLC control, it supports coordinated hoisting, luffing, slewing, and travel motions. Optional intelligent anti-sway, remote monitoring, and condition tracking are also available

Rugged & Safe Durability: The high-strength steel structure, combined with marine-grade corrosion protection, ensures longevity in harsh maritime conditions. Comprehensive safety interlocks and overload systems safeguard intensive operations.
