Why is the MG Gantry Crane the “Top Choice” for Ports and Warehouses?

The MG universal double-girder gantry crane is widely used in open-air storage yards, freight yards, railway stations, and port terminals.It is designed for material handling, loading, unloading, and equipment installation.With stable structure, strong load capacity, and wide working range, it is ideal for medium- and heavy-duty lifting operations.

MG Gantry Crane1

Main Structure

Main Girder

Adopts a double-box structure with high rigidity and excellent resistance to deformation.Standard spans range from 18 to 35 meters (customized larger spans available).

Cantilever

Extends the cranes working range beyond the rails.Options: single-sided, double-sided, or non-cantilever, depending on site needs.

Legs (Gantry Legs)

Available in rigid or flexible types to ensure stable operation on rails.Leg height can be customized to suit different working environments.

Hoisting Mechanism

Includes motor, reducer, brake, drum, wire rope, and hook.Standard lifting capacity: 550 tons (larger tonnage available).Optional dual-hook system (main + auxiliary) for enhanced flexibility.

Travel Mechanism

  • Crane traveling: entire crane moves longitudinally on ground rails, usually with four-wheel drive for stability.
  • Trolley traveling: hoisting trolley moves transversely along the main girder to maximize coverage.

Electrical Control System

Equipped with frequency control or PLC system for smooth starting and precise positioning.Includes limit switches, overload protection, emergency braking, and complies with GB/T 14406 standards.

Selection Guidelines

Capacity & Span:

  • Choose tonnage and span based on real demand.

Working Environment:

  • Outdoor use requires windproof, rainproof, and anti-corrosion design.
  • Extreme temperature requires special customization.

Rail Requirements:

  • Rails must comply with GB/T 3811 standards.
  • Ensure smoothness and reliable grounding.

Operation Modes:

  • Options include cabin operation, remote control, or pendant control.

BMG Double-Girder Semi-Gantry Crane

When heavy loads, large spans, and full ground coverage are required, the MG crane is the best choice.However, when space is limited (such as wall-side operations, across railways, or obstructed by plant columns), the traditional full-gantry may not apply.The BMG semi-gantry crane with one high leg and one low/no leg design solves these issues.It retains the strong load capacity of a double-girder crane (5–100 tons) while adapting to restricted sites.Offering an ideal balance between space efficiency and lifting performance.

Double-Girder Gantry Crane with Electric Hoist

The MG gantry crane is preferred in heavy industries, ports, and railway freight.For lighter applications such as medium-scale material handling, warehouses, and light assembly, the double-girder electric hoist gantry crane is more economical and flexible.

Comparison Item

MG Universal Gantry Crane

Electric Hoist Gantry Crane

Capacity 5–200 tons (heavy loads) 1–20 tons (light to medium)
Span Range 18–35 m (large) 10–30 m (medium)
Lifting Height 10–16 m (customizable) 6–20 m (standard)
Hoisting Mechanism Winch with wire rope + pulley Electric hoist (CD/MD type)
Duty Class A5/A6 (heavy duty, frequent use) A3–A5 (medium frequency)
Drive System Independent motors for crane & trolley Integrated drive in hoist
Speed 20–30 m/min (VFD control) 8–20 m/min (economical)
Structure Double-box girder, high rigidity Double-girder box/truss, lighter

Compared with MG cranes, electric hoist double-girder gantry cranes are more compact, lighter, cost-effective, and easy to maintain.They are especially suitable for 1–20 ton loads with 10–30 m spans in mid-scale operations.
