MDG L-Type Gantry Crane

For yards and ports handling long loads or loads that must rotate through the leg area, where L-shaped legs provide more usable passage than a conventional closed leg layout.

The MDG L-type gantry crane is a single-main-girder gantry crane with a winch hoisting mechanism and L-shaped legs. The source publishes rated capacity of 5–50 t and span of 18–35 m for the product family and positions it for outdoor loading and unloading in yards and ports.

For procurement, the buyer should start with the load length and turning envelope. L-type geometry is most valuable when the suspended load must pass the legs or rotate at a large angle. Cantilever coverage, runway length and outdoor wind conditions then determine the practical yard layout.

Product Overview

Single-main-girder structure with L-shaped legs.

Winch hoisting mechanism.

Source-rated capacity 5–50 t.

Any capacity, span, speed, synchronization accuracy, wind limit, temperature limit, throughput or other contractual value that is not explicitly published by the source should be engineered from the actual project and written into the technical agreement.

Why Choose MDG L-Type Gantry Crane?

Better Long-Load Clearance

L-shaped legs reduce obstruction when beams, pipes or fabricated structures pass the gantry legs.

Published Capacity / Span Range

The source provides 5–50 t and 18–35 m for this product family.

Winch Hoisting

Suitable where a winch-based lifting system is preferred over an electric-hoist arrangement.

Flexible Operator Control

Ground, remote and cabin modes are source-listed.

Smooth Gantry Travel

Three-in-one VFD travel supports smoother start/stop behavior.

Application Scenarios

How to Select the Right MDG L-Type Gantry Crane

1. Provide Load Length and Width

The largest load envelope determines whether the L-leg layout is justified.

2. Define Rotation Requirement

Show the load orientation at pickup, travel and set-down.

3. Confirm Source Range Fit

If the required capacity or span is outside 5–50 t / 18–35 m, request a project-specific review.

4. Define Cantilever / Outside Reach

State any truck or storage position beyond the rail line.

5. Define Outdoor Conditions

Provide wind, rain, temperature and corrosion conditions.

L-Type Layout: What Buyers Should Check

Safety & Control: What Buyers Should Confirm

Installation & Maintenance

Before manufacture, confirm rail center distance, runway length, rail elevation, foundation or building-runway capacity, available lifting height, process clearances, power supply and erection access. Outdoor projects should include wind, rain, temperature, corrosion and anchoring conditions.

Maintenance should follow the final supplied crane manual and actual duty. In addition to hoisting, brakes, ropes, wheels, drives, rails, limits and electrical systems, inspect product-specific devices such as grabs, magnets, gantry hooks, gate equipment, tipping mechanisms, encoders, cameras or automation hardware.

Frequently Asked Questions

How is final crane capacity selected?

Use the complete suspended load, including the load plus grab, magnet, gantry hook, lifting beam, rigging or any other below-the-hook equipment.

Can span and lifting height be customized?

Yes. Unless the source publishes a range, these are project-specific and should be selected from the rail layout and working envelope.

What site drawing should I send?

Send a plan and cross-section showing rails, foundations or building runway, loading positions, obstacles, travel length and available clearances.

Can control or automation be customized?

Where the source supports VFD, PLC, linked operation, cameras, access control or other functions, the final scope should be defined from the buyer's process and acceptance requirements.

How should source-reported performance numbers be used?

Treat them as source product data. If a value is contract-critical for a new project, define the test conditions and acceptance method in the technical agreement.
