Double Main Girders

Two parallel steel beams that form the crane bridge.

Provide high structural strength and stability.

Designed based on required span, load, and application.

 

Gantry Legs

Vertical or inclined supports connecting the main girders to the ground-travel system.

Types include:

A-frame

Box-type

U-frame

Designed to support the crane's structure under dynamic loads.

‌‌

Cab: ‌The frame is made of section steel, ‌the outer shell is made of thin steel plates welded to the frame, and ‌adopts a folded closed design. The electrical appliances, power distribution cabinets and circuits of the control mechanism are generally located in the driver's cab.

‌‌

Hoisting Mechanism (Trolley)

Mounted on top of the girders.

Houses the motor, gearbox, drum, wire rope or chain, and hook/grab/spreader/magnet.

Moves horizontally along the girders to position the load.

Can be customized for speed, load capacity, and control sensitivity.

Advantages of Customized Driven Double Girder Gantry Crane

1. High Load Capacity & Structural Strength

The double girder design supports heavier loads and longer spans compared to single girder models.

Ideal for lifting oversized and heavy objects in industries like steel, shipbuilding, and construction.

2. Tailored Performance

Customized drive systems (motors, gearboxes, frequency drives) allow the crane to match exact operational requirements.

Offers precise control over lifting speed, travel speed, and positioning.

3. Enhanced Operational Efficiency

Drives and components are optimized for fast, smooth, and energy-efficient operation.

Minimizes cycle times and increases material handling throughput.

4. Adaptability to Complex Work Environments

Can be custom-designed for unique site constraints, such as irregular layouts, specific height restrictions, or extreme conditions (e.g., high temperature, corrosive environments).

Suitable for both indoor and outdoor use.

5. Improved Safety and Reliability

Integrated with advanced safety features:

Overload protection

Anti-collision systems

Limit switches

Emergency stop functions

Optional automated control systems reduce human error.

6. Automation and Smart Features

Can be equipped with PLC, HMI, sensors, and remote diagnostics for intelligent control.

Optional semi- or fully-automated modes reduce labor dependency and enhance precision.

7. Longer Service Life

Made from durable, industrial-grade materials with corrosion-resistant finishes.

Custom engineering reduces wear and tear by optimizing performance for actual usage conditions.

8. Flexible Control Options

Multiple control methods:

Cabin control

Wireless remote

Pendant control

Improves operator convenience and safety.

9. Easy Maintenance and Upgradability

Modular design allows easy access for inspection and repair.

Custom systems can be upgraded or integrated with future technologies.

Material Inspection

Quality Inspection: Strict quality inspection is carried out on the purchased raw materials to ensure that they meet the design requirements and national standards.

Material Storage: Qualified materials are stored according to classification to prevent corrosion or damage.

Cutting and Forming

Steel Cutting: Use plasma cutting, laser cutting or flame cutting and other technologies to cut the steel according to the size of the design drawing.

Forming Processing: Form the steel plate through bending, rolling, welding and other processes to manufacture the main beam, end beam and other structural parts.

Welding

Component Welding: The cut and formed steel parts are welded into the main structures such as the main beam, end beam and trolley. The welding process needs to be strictly controlled to ensure the structural strength and welding quality.

Weld Inspection: Use non-destructive testing technology (such as ultrasonic testing, radiographic testing) to inspect the welds to ensure that there are no cracks or other defects.

Machining

Precision Machining: Precision machining is performed on the key components of the crane, such as wheel sets, bearing seats, pulleys, etc., to ensure their dimensional accuracy and surface quality.

Assembly of the whole machine

General assembly: On the basis of pre-assembly, the overall assembly of the crane is carried out, including the final installation of the main beam, end beam, lifting mechanism, walking mechanism, etc.

Commissioning and testing

Under dynamic conditions, the operating performance of the crane is tested, including the testing of lifting, walking, steering and other functions. The overall size of the assembled bridge crane is checked to ensure that all dimensions meet the design requirements.

Spraying and anti-corrosion treatment

Surface treatment Rust removal: Rust removal on the surface of the crane, common methods include sandblasting, pickling, etc. Primer spraying: Spray anti-corrosion primer on the treated surface to prevent metal oxidation and corrosion. Topcoat spraying Color spraying: Spray topcoat according to customer requirements or industry standards to give the crane a protective and decorative effect. Marking: After spraying, mark the crane's identification information in accordance with the specifications, such as model, rated load, etc.

Factory and installation

Packaging and transportation

Packaging protection: Protectively package the key components of the crane to prevent damage during transportation. Transportation arrangement: According to the equipment size and transportation conditions, select a suitable transportation method to transport the crane to the customer's site.

Acceptance and delivery

Customer acceptance

On-site acceptance: The customer conducts on-site acceptance of the crane according to the contract requirements and technical specifications to check the performance and quality of the equipment.

Problem rectification: If any problems are found, the manufacturer needs to rectify them in time to ensure that the equipment fully meets the customer's requirements. Delivery and use Operation training: The manufacturer usually trains the customer's operators to ensure that they can operate the crane correctly and safely.
