Different types of STS - Cranes
•
•
•
•
•
•
lifting capacity under spreader from 30 to 70 tons
hoist speed with full load from 45 to 90 m/min
hoist speed without load from 120 to 200 m/min
trolley speed from 150 to 240 m/min
gantry speed from 30 to 60 m/min
boom hoisting time 4...5 minutes
 Rope Towed Trolley ( RTT) and semi-rope trolley crane / the most commonly used
• throughput up to 30 containers (lifting)/hour (working cycle 2 min for main hoist and trolley)
 Machinery On Trolley (MOT) crane
• used when a slewing trolley and cab is needed
• lifting capacity and trolley speed lower than those of rope trolley cranes
• trolley slew 180 degree in 30 seconds
 Dual Hoist Crane ( DHC)
• used when high container handling capacity is needed
• throughput up to 50 containers (lifting)/hour
