Double Girder Workshop Gantry Crane
Product Introduction
A Double Girder Workshop Gantry Crane is a type of heavy-duty lifting equipment designed for indoor or semi-outdoor industrial applications, particularly in manufacturing workshops, assembly lines, warehouses, and maintenance areas. It features two parallel girders that provide enhanced strength and stability, making it suitable for lifting and moving heavy loads over large spans.
Key Features:
High Load Capacity: With dual girders, these cranes can support significantly heavier loads compared to single girder models, typically ranging from 5 tons to over 100 tons.
Stable Structure: The dual girder design offers increased rigidity and reduces deflection, ensuring safer and more precise handling of materials.
Flexible Configuration: Can be customized with various lifting mechanisms such as wire rope hoists or electric winches, and integrated with advanced control systems.
Optimized for Indoor Use: Ideal for workshops with limited space where overhead cranes are impractical or where structural support is insufficient for overhead rail systems.
Adjustable Span and Height: Designed to fit a range of workshop dimensions, including adjustable leg heights for uneven ground or varying workspace requirements.
Ease of Installation and Mobility: Often mounted on rails or equipped with rubber tires for mobility within a confined area.
Applications:
Heavy manufacturing
Mechanical assembly
Steel fabrication
Equipment maintenance
Large part storage and handling
Double girder workshop gantry cranes are a reliable solution for industries that require efficient, safe, and high-capacity material handling within a confined or partially covered space.

Pictures & Components
Double Girders (Main Beams)
These are the two parallel horizontal beams forming the primary load-bearing structure.
Designed for maximum strength and minimal deflection under heavy loads.
Usually fabricated from welded box-type structures or I-beams
Support Legs
Vertical structures that connect the girders to the traveling mechanism (wheels or bogies).
May be of equal or different heights, depending on the workshop's design.
Provide overall stability to the gantry frame.
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.
Lifting Mechanism (Hoist or Winch)
Positioned on a trolley that runs along the girders.
Can include:
Wire rope hoist for standard lifting.
Electric winch for heavy-duty or precise operations.
The lifting mechanism includes a motor, gearbox, drum, wire rope, and hook.

Advantages
Advantages of Double Girder Workshop Gantry Crane
High Load Capacity
Capable of lifting and transporting much heavier loads than single girder models.
Ideal for handling large, bulky, or heavy equipment and materials.
Greater Stability and Rigidity
The dual girder structure offers superior rigidity and minimal beam deflection.
Ensures safe, stable, and precise material handling, even under full load.
Longer Spans
Suitable for workshops with wide working areas.
Can span larger distances without compromising strength or performance.
Efficient Use of Workshop Space
Frees up floor space beneath the crane for other operations.
Can operate in areas where overhead crane systems cannot be installed due to structural limitations.
Customized Design Options
Tailored to specific workshop dimensions and load requirements.
Can include variable leg heights, cantilever arms, or rotating hoists for flexible handling.
Multiple Control Options
Supports pendant, remote, or cabin control, increasing operational safety and convenience.
Advanced control systems can reduce human error and improve productivity.
High Lifting Height
Offers greater lifting height due to hoist placement between or on top of the girders.
Allows for better handling of tall loads or working in high-ceiling environments.
Durability and Long Service Life
Built from high-strength steel with robust welds and quality components.
Designed to withstand continuous heavy-duty usage in industrial settings.
Enhanced Safety Features
Equipped with multiple safety systems, including limit switches, overload protection, and emergency stops.
Minimizes risk of accidents and equipment damage.

Crane production procedure
Workshop view
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.
