01 / PROJECT CONTEXT

The project and its handling task.

Henan Mine Crane supplied a 750 t double-girder gantry crane for a Zhejiang project, where it entered use. The structure and travel arrangement were customized to the site’s heavy-handling conditions.

One side uses a double-rail design to reduce wheel pressure. PLC and inverter communication control coordinate multiple lifting points with automatic balance adjustment. High-strength special steel supports the structure, while 10 kV power and energy recovery during lowering form part of the electrical configuration.

02 / HANDLING REQUIREMENTS

Move extremely heavy assemblies while managing runway pressure.

A 750 t yard lift can challenge wheel loads, travel control and power supply before the first component is moved.

Full assembly and rigging mass

Calculate assembly, rigging and support loads at each pickup point.

Civil and wheel-load limits

Balance lifting points and control gantry travel over the chosen rail layout.

Lift-point spacing and route

Monitor load distribution and movement through final placement.

Electrical supply and recovery plan

Monitor load distribution and movement through final placement.

06 / PROJECT OUTCOME

In operation.

The 750 t gantry entered operation at the Zhejiang project. Its rail and synchronized-lifting arrangements respond to site loading and heavy component handling requirements.

For a similar project, coordinate the gantry, runway and supply system as one package. Multi-point synchronized lifting, monitored travel, a site-specific dual-rail arrangement and regenerative power are evaluated against the real lifting cycle.

07 / PLAN A SIMILAR PROJECT

Prepare a comparable crane quotation.

Share the load schedule and site drawings. Coordinate the gantry, runway and supply system as one package. Multi-point synchronized lifting, monitored travel, a site-specific dual-rail arrangement and regenerative power are evaluated against the real lifting cycle.

We can quote a single crane or a coordinated fleet. The offer sets out the destination standards, required certificates and inspection records, manufacturing programme after drawing approval, shipment, installation support and agreed acceptance scope.

BUYER QUESTIONS

Questions before specifying a similar crane.

Can the same project crane be supplied for my site?

We customize the capacity, span, lifting height, attachment and controls to the load, building or yard layout and operating cycle. Full assembly and rigging mass is one of the inputs to review before final equipment selection.

How are certification, quantity and lead time agreed?

Single-crane and fleet enquiries are welcome. Define the destination and required standards in the enquiry. The project offer confirms certification and inspection documents, the quantity, drawing approval and manufacturing schedule, with the shipping and site-service boundaries.

What should acceptance and after-sales support include?

Agree the inspection plan, representative load and functional tests, operator training, maintenance instructions, spare-parts scope and fault-recovery procedures. For this application, include electrical supply and recovery plan in the technical review.
