Rail-mounted container gantry crane

Structure and operating principle

A rail-mounted gantry moves containers across a defined container-yard working area.

A container gantry combines a travelling lifting trolley with a spreader and its locking system. The chassis runs on rails or tyres according to the model, affecting route control, positioning and parking arrangements.

Application and selection

For container-yard stacking and transfers to the designated landside transport lane. Container dimensions, gross mass, stack geometry and the spreader mode must match the approved operating configuration.

Working method

1. Before work, authorised personnel confirm the load and its centre of gravity, the permitted machine configuration, the route and receiving position. Complete the checks specified for the equipment, verify protective functions by the approved method and stop if a defect affects safe operation.

2. Confirm the correct container and release of external restraints, align the spreader and verify engagement before lifting. Travel with the required clearances, land fully and confirm load support before unlocking.

3. After the task, place the load on stable supports and leave the equipment in its prescribed safe state. Record faults and abnormal events. Maintenance or jam clearance requires secure isolation of relevant energy, including stored hydraulic, pneumatic and gravitational energy.

Precautions and maintenance

Do not lift a container still secured to a vehicle, ship or adjacent container. Protect handover lanes and use the machine’s wind, storm-securing and emergency-lowering instructions; spreader indication faults require stopping and investigation.

Inspection frequency, wear/discard criteria, lubrication, brake adjustment and replacement parts follow the supplied instructions and applicable local requirements. Only competent personnel may maintain the equipment; return to service follows the prescribed checks.

Configuration and standards

This is an equipment-selection and operating-principle overview, not a complete operator manual, lift plan or certificate. Verify rated load, duty, geometry, environment and protective functions against the nameplate, approved drawings and delivered instructions. Do not combine separate series maxima into one promised configuration.

Requirements follow the destination and installation, not the website language. China: determine the applicable GB/T references and statutory equipment obligations. EAEU destinations: check the applicable TR CU/EAEU regulations, amendments and conformity documents. English-speaking markets: select the relevant national rules; US OSHA and UK HSE references are not universal law. EU projects require their own applicable conformity assessment.
