Ship-to-shore container crane

Structure and operating principle

A quayside crane transfers containers between ships and the landside handling area.

The quayside crane moves a spreader between the ship’s container positions and the landside handover area. Boom, trolley, hoist and crane travel have interacting clearance limits around the vessel and quay.

Application and selection

For planned ship-to-shore container operations coordinated with vessel and terminal personnel. Vessel geometry, tide or movement, lashing status and the landside traffic plan are part of each working arrangement.

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 operating bay and lashing clearance, engage and verify the spreader, then transfer only after the container is free. Land at the authorised receiving point and release after support is confirmed; coordinate boom movement separately.

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

Maintain clearance from ship structures and personnel. Follow crane-specific wind warnings, shutdown and securing procedures; do not use one generic wind speed for every boom position or load condition.

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.
