PRODUCT INTRODUCTION

The Four Link Portal Crane is a mobile, full-revolving harbor crane featuring a balanced four-bar combined jib system. Its main steel structures include the jib, A-frame, slewing platform, and gantry frame—available in cylinder or four-outrigger configurations. The crane integrates hoisting, luffing, slewing, and travel mechanisms, and supports multiple spreader types including grab, container spreader, hook, and electromagnetic disc.Designed for long-reach operations and larger vessels, this crane delivers reliable, durable performance with easy maintenance. It is an optimal solution for comprehensive, multi-cargo port operations. Applicable Standards: GB17495, GB6067, GB3811, ISO, FEM, JIS.

FEATURES

Four-Mechanism Coordination: Equipped with hoisting, luffing, slewing, and traveling mechanisms that can operate independently or in coordination, significantly improving handling efficiency

Level Luffing Technology: The core advantage lies in the four-bar jib system, which ensures the hook follows a near-horizontal trajectory during luffing, resulting in stable load movement and low energy consumption.

Quick Spreader Change: Features a standard quick-change interface, allowing seamless switching between hook, grab, and container spreader within 3-5 minutes, adapting to various cargo types

Wide Operating Range: The jib can rotate 360°, covering the entire quayside area. Its design accommodates various ship sizes and handles bulk, general, and containerized cargo

Automation & Intelligence: Can be equipped with a CMS intelligent monitoring system for real-time status tracking, alongside automated features like grab auto-cycle, anti-sway control, and jib anti-collision systems.

Energy-Efficient & Eco-Friendly: Utilizes AC frequency control for smooth starts and energy savings. An optional active inverter technology can feed braking energy back into the power grid.
