- 3 Power Options – Diesel / Cable Reel / Battery
- 5-25T – Right-Sized for Standard Industrial Loads
The DTL Series is a single girder rubber tyred gantry crane designed for light to medium capacity industrial handling, with typical applications involving standardized loads and repetitive lifting operations. Its optimized structure helps reduce equipment weight and initial investment, while its simplified electric drive system and standardized components help keep operating and maintenance costs predictable.
Optimized DTL Design for Lower Initial Investment
The DTL Series rubber tyred gantry crane reduces initial investment through three practical design features: a single-girder structure that reduces equipment weight, rubber-tyred operation that eliminates permanent rail infrastructure, and modular construction that simplifies transportation and installation.
Optimized Single Girder Structure for Lower Equipment Investment
- Efficient Structural Design: The DTL adopts an FEM-based box girder design with controlled pre-cambering to optimize load distribution and ensure structural stability during lifting operations.
- Optimized Structural Weight: The single girder configuration reduces steel consumption and overall equipment weight while maintaining the required strength and rigidity for standard industrial handling tasks. The reduced structural weight helps lower manufacturing, transportation, and installation costs.
Rubber-Tyred Design Without Rail Infrastructure
- Reduced Infrastructure Requirements: Operating on heavy-duty engineering tyres, the DTL does not require permanent rails or runway foundations. This reduces civil construction requirements and lowers site preparation costs.
- Flexible Site Deployment: The DTL can operate on prepared concrete, asphalt, or compacted yard surfaces, making it suitable for existing facilities, temporary yards, and expanding industrial sites without major infrastructure modifications.
Modular Design for Simplified Transportation and Installation
- Modular Configuration: The DTL is built in modular sections for easier transportation and on-site assembly, reducing installation labor and auxiliary equipment requirements.
Reliable Systems for Lower Operating Costs
Beyond initial investment, daily operating costs determine the long-term value of industrial handling equipment. The DTL Series adopts a reliable electric drive system with standardized components and practical engineering solutions, helping operators simplify maintenance, reduce downtime, and achieve predictable lifecycle costs.
Standard Electric Drive System for Easier Maintenance
The DTL uses mature electric drive technology for hoisting, trolley travel, and gantry movement, providing a reliable and maintainable solution for standard industrial handling applications.
Widely Available Electrical ComponentsThe use of standardized motors, gear reducers, control systems, and frequency converters improves spare parts availability and simplifies long-term maintenance planning.
Reliable Power Supply for Trolley MovementThe trolley uses a C-rail festoon cable system to provide stable power transmission. The organized cable arrangement improves operational reliability, reduces cable damage risks, and keeps the equipment structure clean and easy to maintain.
Simplified TroubleshootingIndustrial aviation quick-connect plugs are used for key electrical connections, reducing field wiring requirements, minimizing connection errors, and making installation, inspection, and fault diagnosis more efficient.
VFD Control for Smooth and Efficient Operation
The DTL integrates variable frequency drive (VFD) technology to improve motion control and reduce mechanical impact during operation.
Smooth Acceleration and BrakingVFD control enables gradual speed changes during starting and stopping, reducing sudden loads on the structure, drive system, and tyres.
Precise Load PositioningAdjustable travel and hoisting speeds allow operators to achieve accurate positioning during material handling operations.
Reduced Mechanical StressSmooth motion control helps reduce wear on mechanical components and supports longer service life.
Reliable Hoisting System for Daily Industrial Operations
The DTL is equipped with a robust electric hoisting mechanism designed for frequent handling cycles.
Durable Hoisting ComponentsHigh-strength galvanized wire rope, forged hooks, and wear-resistant transmission components provide reliable performance under continuous industrial use.
Stable Lifting PerformanceDual-speed or VFD hoisting control enables smooth lifting and lowering, reducing load impact and improving operator control.
Long Service Life DesignOptimized lifting components and proper lubrication systems reduce maintenance frequency and support consistent operation.
Designed for Standard Loads with Predictable Handling Requirements
The DTL Series is a practical rubber-tyred gantry crane designed for efficient handling of standard industrial loads. With an optimized single-girder configuration, DTL delivers reliable lifting performance and flexible yard operation without unnecessary system complexity.
DTL is best suited for facilities where:
- Lifting requirements are within light to medium capacity ranges.
- Loads have predictable dimensions and defined lifting methods.
- Handling frequency is high but load complexity is limited.
Typical applications include:
Precast Concrete Components: Standard slabs, wall panels, beams, and other precast products with defined lifting points, transferred between production and storage areas.
Steel Products: Plates, profiles, pipe bundles, and fabricated components handled through regular manufacturing, storage, and loading operations.
Industrial Modules and Equipment: Machinery bases, equipment frames, and modular units with standardized lifting arrangements and predictable handling requirements.
