MHE double hoist gantry crane

Technical Configuration

Technically, the MHE double hoist gantry crane is built to project-specified parameters, with capacity, span, and lifting height all determined by the buyer’s operational needs. The crane features a single-girder box structure, typically fabricated from Q235B or Q345B steel per GB/T 3811 crane design standards, with the option of single-end outrigger cantilever or no-cantilever configurations. The two electric hoists travel along the bottom flange of the main girder, each powered by a separate motor and control system. Standard electrical components are from leading Chinese suppliers, with Schneider or Siemens electrics available as an upgrade for buyers requiring European-grade reliability. Power supply is three-phase AC 50Hz, 380V (other voltages available on request), and the working environment temperature range is -20°C to +40°C. Control options include cabin operation, wireless remote control, or pendant control, depending on site conditions and operator preference. Safety devices include overload limiters, travel limit switches, emergency stop buttons, and anti-collision buffers between the two hoists. Optional features include variable frequency drives (VFD) for smooth acceleration and deceleration, corrosion-resistant paint for coastal environments, and explosion-proof hoist configurations for hazardous zones (excluding flammable or explosive materials).

This crane serves a broad range of heavy industries. In steel mills, it handles coils, billets, and scrap metal with the dual hoists distributing weight across long spans. Port and intermodal yards use it for container and bulk cargo transfer, where the two hoists can lift unevenly loaded containers or pallets. Precast concrete plants rely on the MHE for lifting molds, rebar cages, and finished segments, with the independent hoists allowing precise alignment during assembly. Warehouses and logistics centers with high-density storage benefit from the crane’s ability to simultaneously lift and move multiple loads, reducing handling time. Energy sector applications include wind turbine component assembly and transformer handling in substations. The machine is also common in shipbuilding for plate and section handling, where the dual hoists provide the stability needed for long, heavy materials.

Buying directly from Chunhua Crane offers significant commercial advantages. As a manufacturer founded in 2003 with in-house engineering and fabrication, we provide factory-direct pricing typically 30 to 50 percent below equivalent European brands, with no intermediary markup. The MHE double hoist gantry crane can be supplied with CE certification for European markets or CCC certification for Chinese projects, and all designs comply with FEM, DIN, or CMAA standards as requested. Our engineering team provides custom structural calculations and CAD drawings within four hours of receiving your inquiry, ensuring the crane fits your exact span, lifting height, and site constraints. We have exported to over 60 countries across Asia, Africa, the Middle East, Europe, and the Americas, with sea freight arranged from major Chinese ports including Shanghai, Ningbo, and Shenzhen. Optional on-site installation and commissioning services are available for buyers who require turnkey delivery.

The ordering process is straightforward and designed for international buyers. Initiate your inquiry via WhatsApp or email with your required capacity, span, lifting height, and control preference. Our sales engineers respond with a detailed quotation and preliminary CAD drawing within four hours. Upon acceptance, we require a 30 percent T/T deposit to begin production. Manufacturing takes 30 to 45 days, depending on customization complexity, during which we provide weekly progress updates. After completion, the crane is disassembled, loaded into containers or onto flat racks, and shipped via sea freight. Full documentation, including packing list, bill of lading, and certificates, is provided. Optional installation supervision by a Chunhua technician can be arranged at the buyer’s site.
