Gantry crane for subway

Technical Configuration

Technical configuration of the subway gantry crane is fully customizable to project specifications, with capacity, span, and lifting height all determined by the buyer’s site requirements. The crane can be designed as a single-girder or double-girder structure depending on load demands and operational clearance. The trolley is equipped with a hydraulic turning mechanism comprising a dedicated hydraulic workstation and a slag turning hook, allowing for 180-degree rotation of soil containers. A central hook on the hanging beam handles general lifting tasks such as tunnel segments, rebar cages, and equipment. The main electrical system can be specified with Schneider or Siemens components for reliable performance and global serviceability. Control options include cabin operation for direct visibility, radio remote control for operator mobility, or pendant control for simple on-site commands. Safety devices are comprehensive: overload limiters, emergency stop systems, travel limit switches, anti-collision buffers, and wind speed anemometers for outdoor use. Optional features include variable frequency drives for smooth acceleration, anti-sway technology for precise load positioning, and corrosion-resistant coatings for humid underground environments. The crane is designed and manufactured in accordance with GB/T crane standards, with optional compliance to FEM, DIN, or CMAA standards upon request.

This gantry crane serves a range of heavy industries beyond subway construction. It is widely used in steel mills for handling scrap metal and finished coils, in ports and rail yards for container and bulk cargo transfer, in precast concrete plants for moving heavy molds and segments, in warehouse and logistics centers for large-scale inventory management, in mining operations for ore and equipment handling, and in general manufacturing facilities requiring reliable overhead lifting. The hydraulic turning feature makes it particularly valuable in any application where controlled rotation of heavy loads is necessary, such as in foundries and scrap processing yards.

Buying directly from Chunhua Crane delivers significant cost advantages, with factory pricing typically 30 to 50 percent below equivalent European brands while maintaining comparable quality and performance. All cranes are available with CE certification for European markets and CCC certification for Chinese domestic projects. Our in-house engineering team provides custom design services to adapt the crane to specific site constraints, including limited headroom, narrow gauge, or extreme ambient conditions. We respond to technical inquiries and provide preliminary CAD drawings within four hours of receiving your request. With over two decades of export experience, we have shipped cranes to more than 60 countries, and our logistics partners offer competitive sea freight rates for worldwide delivery.

The ordering process is straightforward and efficient. Begin by contacting us via WhatsApp or email with your project requirements, including capacity, span, lifting height, and any site-specific constraints. Our engineering team will respond with a detailed quotation and preliminary CAD layout within four hours. Upon acceptance, a 30 percent T/T deposit is required to initiate production. Manufacturing typically takes 30 to 45 days, depending on customization complexity. After production, we arrange sea freight to your designated port, and optional on-site installation and commissioning services can be provided by our experienced field engineers.
