Rail-mounted container gantry crane

Technical Configuration

Technical configuration is entirely project-specified, meaning capacity, span, and lifting height are engineered to match the customer’s exact container handling demands, typically ranging from 20 tons to 50 tons capacity, spans from 18 meters to 40 meters, and lifting heights from 8 meters to 18 meters. The crane structure is available in non-cantilever, single-cantilever, or double-cantilever configurations, determined by the yard layout and whether the crane must service container trucks or railway cars on one or both sides. The main beam is a box-type welded structure, supported by one rigid leg and one flexible leg to accommodate thermal expansion and rail alignment tolerances. The hoisting mechanism uses a dedicated wire rope hoist with a spreader beam, and the trolley traverses across the main beam. Travel is provided by a cart running mechanism with frequency-controlled motors on standard gauge rails. Electrical systems are built to international standards, with Schneider or Siemens components as optional upgrades, and the control system supports three modes: a fully enclosed operator cabin with HVAC, a wireless remote control for ground-level operation, and a pendant control for maintenance or fine positioning. Safety devices include overload limiters, travel limit switches, anti-collision buffers, rail clamps, and wind speed anemometers for outdoor installations. Optional features can include automatic container identification, remote monitoring systems, and spreader twist-lock automation.

This crane serves a broad range of heavy industries and logistics environments. Primary applications include container terminals and intermodal rail yards for stacking and transferring ISO containers, steel mills for handling coils and slabs in storage bays, large warehouses and distribution centers requiring high-density block stacking, cement and bulk material plants for loading and unloading flatbed trucks, railway freight stations for container-on-flatcar operations, and heavy machinery manufacturing facilities for moving oversized components between assembly and shipping areas. The rail-mounted design ensures precise positioning along a fixed path, making it ideal for operations where wheeled mobile cranes would require excessive turning space or create ground pressure issues.

Buying directly from Chunhua Crane offers a clear cost advantage, with factory pricing typically 30% to 50% below equivalent European-branded equipment, without compromising on structural integrity or performance. All cranes can be supplied with CE certification for European Union projects, CCC certification for Chinese domestic use, and are designed to meet FEM, DIN, CMAA, or GB/T crane standards as specified. Our engineering team provides full custom design, including structural calculations and finite element analysis, and we commit to a 4-hour quotation response time for all technical inquiries. We have shipped cranes to over 60 countries via sea freight, with full documentation for customs clearance, and can arrange optional on-site installation and commissioning by our international service engineers.

The ordering process is straightforward and efficient. Initiate an inquiry via WhatsApp or email with your required capacity, span, lifting height, and any site-specific constraints. Our engineering team responds with a detailed quotation and preliminary CAD drawing within four hours. Upon acceptance, a 30% T/T deposit secures the production slot. Manufacturing takes 30 to 45 days, during which we provide progress photos and test certificates. The remaining 70% balance is due before sea freight shipment. We handle all packing, loading, and shipping documentation, and optional installation supervision can be arranged at the destination port or yard.
