Single girder gantry cranes feature simple structures, flexible operation, and cost-effective pricing. They are primarily used for material loading, unloading, handling, and short-distance transportation in various settings, including indoor workshops, open-air warehouses, storage yards, and port terminals.
A single girder gantry crane is composed of several key components, each carefully designed to ensure strength, stability, and reliable operation under various working conditions.
♦Box Girder (Main Beam): The main girder adopts a box-type cross-sectional structure, which provides high rigidity and excellent bending resistance. It is typically manufactured from high-strength steel plates such as Q345B or Q235B to guarantee sufficient mechanical performance. Advanced welding processes are used to ensure overall structural integrity, while reinforcement ribs are added at critical stress points to enhance torsional strength and load-bearing capacity.
♦Drive Mechanism: The traveling mechanism of the single girder gantry crane uses a compact three-in-one drive unit that integrates the motor, reducer, and brake into a single system. This design improves operational reliability and safety while reducing maintenance requirements. A three-phase AC variable frequency motor ensures smooth acceleration and deceleration, while the hard-tooth surface reducer delivers stable torque transmission. The electromagnetic brake is equipped with asbestos-free brake pads for safe and environmentally friendly operation.
♦Electrical System: The electrical control system is equipped with frequency converters, allowing flexible adjustment of running speed, micro-speed, and dual-speed operation. This ensures smooth lifting and traveling with low inertia and minimal impact. The control cabinet features a rational layout for easy inspection and maintenance, with a high protection rating up to IP55 to suit harsh environments. Multiple power supply options are available to meet different site requirements.
♦Wheel Assembly: The wheels are made from high-quality alloy steel such as 40Cr or 42CrMo and undergo overall heat treatment for high hardness and excellent wear resistance. Self-aligning bearings are used to improve stability and extend service life of the single girder gantry crane. The modular wheel design, combined with buffer devices, allows customization for various tracks and working conditions.
When selecting a single girder gantry crane, it is important to evaluate both your operational needs and long-term performance expectations. Below are practical purchasing guidelines to help you make an informed decision.
♦Clarify Application Requirements: Start by defining the working environment and usage frequency. Consider the maximum load weight, required span, lifting height, and travel distance based on the materials being handled and the available site space. For high-frequency or continuous operations, a higher duty classification should be selected to ensure durability and stable performance.
♦Focus on Cost–Performance Balance: Rather than choosing the lowest-priced option, assess the overall value of the crane. A well-designed 10 ton single girder gantry crane should offer reliable performance, efficient operation, and reasonable energy consumption. Balancing initial investment with long-term operating and maintenance costs will result in better economic returns.
♦Choose a Reliable Manufacturer: Quality assurance is critical. Select a manufacturer with proven experience, complete certifications, and a strong track record in gantry crane production. Reputable suppliers typically apply strict quality control standards and use certified components, ensuring safety and service life.
♦Evaluate After-Sales Support: Comprehensive after-sales service is essential for smooth operation. Ensure the supplier can provide installation guidance, operator training, regular maintenance support, and fast access to spare parts. Strong technical support minimizes downtime and extends the 10 ton single girder gantry crane lifespan.
♦Customization Capability: Single girder gantry cranes can be customized to match specific load capacities, spans, lifting heights, and functional requirements. For precise technical solutions and model selection, consulting the supplier’s engineering team is highly recommended.
