This document compares different types of container terminal handling equipment, including ship-to-shore gantry cranes (STS), rubber tired gantry cranes (RTG), rail mounted gantry cranes (RMG), container lift trucks (CCTI), reach stackers (RS), and straddle carriers. It provides details on the productivity, transfer capabilities, stacking density and selectivity, roadway requirements, and labor costs for each type of equipment.
2. (STS)SHIP-TO-SHORE GANTRY CRANES
•Productivity is 24 per hour
•1 STS transfer to 1.7 RTG
•1 STS work with 6 terminal truck
•1 STS transfer to 1 reach stacker
•Single Lift
•20’ / 40’ / 45’ manual
•20’ / 40’ / 45’ telescopic
•Twin Lift
•• 2 x 20’ units per lift
•Often limited to handling MT containers
•Needs appropriate stows on vessel
3. (RTG) RUBBER TIRED GANTRY CRANES
•Productivity 18 per hour
•2 RTG transfer from 1 STS
•1 RTG work with 4 terminal truck
•High density stacking – selectivity issues for
•random import delivery
•Narrow roadways – sufficient for trucks and ITVs
•Needs ITVs – labor cost impact
•Can be semi-automated / automated
•Reduce demand for truck waiting areas at gate
4. RAIL MOUNTED GANTRY CRANES
(RMG)
•Productivity 30 per hour
•1RMG transfer from 1 STS
•Working in lane can't shifting
•Can work in two sides lift and right
•Work with 6 terminal truck
•High density stacking – selectivity issues for
•random import delivery
•Narrow roadways – sufficient for trucks and ITVs
•Needs ITVs – labor cost impact
•Can be semi-automated / automated
•Reduce demand for truck waiting areas at gate
5. (CCTI) CONTAINER LIFT TRUCKS
•Productivity 18 per hour
•1 CCTI transfer from 1 STS
•1CCTI work with 6 terminal truck
•Work with empty container only
•Work in MT container area
•Wide roadways – requires largest area
•Moderate density stacking
•Poor selectivity
6. REACH STACKER (RS)
•Productivity 20 per hour
•1RS can transfer from 1 STS
•1 RS work with 6 terminal truck
•Wide roadways – requires largest area
•Moderate density stacking
•Poor selectivity
7. STRADDLE CARRIERS
•Productivity 20 per hour
•Working as handling and transfer equipment
•Medium density stacking – good selectivity issues for
•random import delivery
•No roadways but needs interchange areas
•Lifts, carries, drops – no need for ITVs – labor cost
•Can be semi-automated / automated (Patrick's)
•Imports and exports can be mixed in stacks
•Increases area required for truck waiting at gate (less
•trucks in the CY)
