Mechanical Spreaders:
· Early designs requiring manual twistlock operation (common on shipboard cranes)
Semi-automatic Spreaders:
· Hydraulic twistlock systems (e.g., Konecranes' Twistlock technology) compatible with 20'/40'/45' containers
Fully Automatic Spreaders:
· Smart recognition (laser scanning + AI vision, like ZPMC's intelligent spreader)
· Remote control systems (ZPMC's 5G remote spreader with <10ms latency)
