Product Introduction

A 40 ton gantry crane is a heavy-duty material handling system engineered for large-scale maritime and industrial environments. Functioning as a high-capacity Portal Crane, it efficiently transfers massive logistical loads. By bridging the operational gap between a rail mounted gantry crane and a floor mounted jib crane, this specialized dock crane provides a highly reliable crane harbour solution for intensive global B2B lifting operations.

What is the Portal Gantry Crane?

Our portal crane is specifically configured as a four-bar linkage system operating on precision ground tracks with a 10.5m span. The specialized four-bar linkage mechanism guarantees that the payload travels in a strictly horizontal path during luffing motions. This advanced structural geometry significantly lowers operating power consumption, minimizes dangerous pendulum swing, and maintains exceptional stability when handling maximum capacities at a 10.5-35m working radius.

Key Features

• Robust Structure: Engineered to support a 510,000 kg total equipment weight, effectively resisting dynamic maritime winds and continuous operational stress.

• High Safety Performance: Equipped with premium Schneider electrical parts and strict overload protection limiters for secure daily operations.

• Precise Load Control: Advanced cabin control systems ensure exact positioning and smooth deceleration during heavy cargo transfers.

• Easy Maintenance: The modular arrangement of the core engine, PLC, and gearbox allows rapid technical access and troubleshooting.

• Long Service Life: Heavy-duty industrial components are integrated to withstand continuous daily usage in harsh seaport conditions.

• Energy Efficiency: The optimized four-bar linkage system minimizes luffing resistance, conserving substantial power across the electrical grid.

FAQ Module

Q: What are the lifting speeds of this 40 ton gantry crane?

A: This lifting system delivers highly efficient operation, achieving lifting speeds of 50m/min when fully loaded and up to 70m/min without a load.

Q: Does this equipment support operations in automated container logistic yards?

A: Yes, equipped with premium Schneider electrical components and advanced PLC systems, it integrates seamlessly into modernized, high-frequency terminal setups.

Q: What makes the four-bar linkage design superior for port applications?

A: The four-bar linkage mechanism keeps the load perfectly horizontal during luffing at speeds of 55m/min. This significantly reduces motor strain and completely eliminates load pendulum effects.

Q: Can this heavy machinery operate on standard industrial power grids?

A: It is engineered to accommodate standard 3 Phase AC 380V 50HZ grids or specific high-voltage power supplies, depending entirely on your terminal's infrastructure.
