Advantages of L-Type Single Girder Gantry Crane

1. Strong & Space-Saving Design

Box-Shaped Gantry Structure: Makes the crane durable and stable for heavy lifting.
L-Shaped Legs: Give more lifting space and strong spanning ability, helping move goods smoothly from the span to under the jib.
Single-Girder Bias Track: Lighter weight but still strong, good for loads ≤50t and spans ≤35m.

2. Flexible & Safe Operation

Multiple Control Options: Can be operated from a cabin, remote control, or pendant line.
Optimized Crab Movement:

Vertical reaction wheel (for loads <20t)
Horizontal reaction wheel (for loads >20t)

Precise Hook Speed Control: Ensures safe and efficient work area coverage.

3. Comfort & Safety for Operators

Closed Cab with Ergonomic Design: Includes an adjustable seat, insulated flooring, and toughened glass.
Optional Add-Ons: Air conditioning, alarms, fire extinguishers, and intercoms for extra safety.

4. Low Cost & Easy to Install

Simpler Structure: Lighter than double-girder cranes, reducing manufacturing and shipping costs.
Quick Assembly: Uses bolt-on sill beams and legs; main girder is placed on hang beams with hoist under slot steel.

5. Wide Range of Uses

Works well for steel ladles, long tubes, and bulky materials because of the L-shaped legs, which allow easy trolley movement and cargo overturning.
Common in warehouses, workshops, and construction sites due to its compact size and high capacity.

Key Features

✅ Overload & Low-Voltage Protection – Improves safety.
✅ Pendant + Remote Control – Flexible operation.
✅ Easy Maintenance – Low downtime and upkeep costs.
✅ Strong Spanning Ability – Handles materials well in tight spaces.

Why Choose This Crane?

Compared to double-girder cranes, the L-Type Single Girder Gantry Crane is lighter and more cost-effective but still performs well. It is perfect for medium-duty lifting with good maneuverability and space-saving design.

More Details

The L-Type Single Girder Gantry Crane uses the space under the main girder efficiently. It is widely used outdoors for loading and unloading materials. It has two control options: ground control and cabin control. It can also be equipped with grabs, electromagnetic chucks, or special trays, customized for different needs.

Applications

With hooks: Used in open storage or rail-side areas for general loading and material handling.
Industries:

Granite
Cement pipes
Shipyards
Steel plants
Storage yards
Construction

Safety Features

Overload Protection: Sounds an alarm if the load is too heavy.
Limit Switches: Prevent the hook from going too high or too low.
Polyurethane Buffers: Durable and long-lasting.
Two Control Modes: Cabin or remote control.
Low-Voltage Protection.
Emergency Stop: Stops the crane quickly in emergencies.
Overcurrent Protection.

Structure & Design

The crane includes a main beam, legs, lower beam, trolley, electric hoist, limit switches, and control system. The gantry can have double cantilevers, single cantilevers, or no cantilevers.

For outdoor use, it has rail clamps and anchoring devices for wind protection. The main beam is a box-type structure, lighter but slightly less rigid than double-girder cranes.

Product Features

Easy to make and install, with good stress distribution.
Lightweight but with slightly less cargo space past the legs.
Simple manufacturing process.
Includes emergency stop, short-circuit protection, and phase-sequence protection.
Independent control for lifting, trolley, and gantry movements.
Adjustable trolley limit switches.
Built-in cable slide system for power supply.
Equipped with overload limiter and limit switches.

Best Uses

Ideal for long or bulky materials, allowing flexible loading positions. Often used for lighter loads and less frequent operations.

The L-Type Single Girder Gantry Crane is a key part of modern machinery. Its design focuses on stiffness, stability, and strength, with three main steps:

Estimate structure size and check stiffness, stability, and strength.
Select materials and create the design.
Verify the gantry’s stiffness and strength.

APPLICATION SCENARIO

Where to Use L-Type Single Girder Gantry Crane

The L-Type Single Girder Gantry Crane works well in many places. It has strong L-shaped legs and an electric hoist. It can lift heavy loads easily.

1. Outdoor Work

Storage Yards & Open Areas: Moves steel, machines, and raw materials.
Train Stations & Ports: Loads and unloads cargo, containers, and pipes.
Docks & Shipyards: Handles heavy equipment near water.

2. Warehouses & Factories

Large Warehouses: Carries heavy pallets and materials.
Workshops: Lifts steel, pipes, and building supplies with care.

3. Construction & Heavy Work

Building Sites: Helps put up steel beams and concrete parts.
Scrap Yards: Moves metal waste and big junk.

4. Special Jobs

Long Items: The L-shape lets it carry pipes, wood, and girders easily.
Tight Spaces: Fits where bigger cranes cannot work.

Why Pick This Crane?

✔ Saves Space: The L-shape helps move goods smoothly.
✔ Easy Control: Use a cabin, remote, or pendant.
✔ Strong & Safe: Works well even outside in bad weather.
✔ Cost Less: Cheaper than double-girder cranes.

More About This Crane

This crane is good for open yards and train tracks. It moves long items better than double-girder cranes. The L-shape makes it shorter, saving money. It also weighs less and has low wheel pressure. Our cranes lift 5 to 50 tons.

The name comes from the "L" shape between the legs and beam. It works well in ports, shipyards, and open areas. It can move goods over the legs and past the track.

5 Key Features

Strong & Easy to Use: Made for fast setup and wide use.
Big Lifting Space: The box-shaped frame moves goods from inside to outside the track.
Safe: Has overload and low-voltage protection. The cabin is closed with strong glass and insulated floors.
Runs Smoothly: Uses top-quality steel, lasts long, and rarely breaks.
Lifts Heavy Loads: Handles 3 to 100 tons with spans up to 12m.
