The ME Type Double Girder Gantry Crane is a special structural variant of double-girder gantry cranes. Its most prominent feature is the equipping of two independent hoisting trolleys, enabling functions such as independent operation of a single trolley, cooperative lifting by two trolleys, overturning of large components, and simultaneous hoisting of two loads. It is commonly used in scenarios with high requirements for lifting coordination or total lifting capacity, including hoisting of road and bridge precast components, installation of large structural members, shipbuilding, heavy equipment hoisting, and port/terminal operations.

Technical Parameters

Lifting Capacity	Typically ranges from 5 to 500 tons; metallurgical models can reach over 800 tons.
Lifting Height	12 to 50 meters, with port models typically exceeding 30 meters.
Span	18–50 meters, customizable up to 60 meters for non-standard applications.
Work class	A5–A7, metallurgy models A7–A8.
Travel speed	20–60 m/min (variable frequency), with optional precise positioning ±5 mm.
Control method	Ground handle/remote control/cab, configured according to requirements.
Power voltage	Customizable according to requirements.

ME TYPE GANTRY CRANE PARTS

Double Main Girders: The main girders consist of either double box girders or double truss girders. Box girders offer high rigidity but slightly greater wind resistance. Truss girders are lighter in weight, have a smaller frontal area facing the wind, and are easier to dismantle and transport. The two main girders are arranged in parallel, forming a stable "double-girder bridge" structure.

Double Supporting Legs: There is one pair of supporting legs on each side, or four independent rigid legs. The legs are connected to the main girders either rigidly or via hinges. The lower parts connect to the end carriages (sills), on which the long travel wheel assemblies are mounted.

Double Trolleys on the Same Track: Two hoisting trolleys share the same pair of main girder tracks, operating in a parallel translation mode on the same rail. They can run independently or be synchronized for coordinated or relative movement, enabling complex operations such as tandem lifting, load turning, and precise positioning.

Product advantages
