FAQ – Ship to Shore Container Crane

Q1: What is a Ship to Shore Container Crane?

A1: A Ship to Shore (STS) container crane is a large quay crane used at container terminals to load and unload containers between vessels and the quay. It is one of the most important pieces of equipment in modern port operations.

Q2: What is the lifting capacity of an STS crane?

A2: The rated lifting capacity typically ranges from 40 des tonnes à 120 tonnes, depending on the design and whether the crane is handling single, twin, or tandem containers.

Q3: Can STS cranes be customized?

A3: Yes. Parameters such as outreach, lifting height, portée, lifting speed, and automation features can be customized to meet the specific needs of a port or shipping terminal.

Q9: What is the difference between STS cranes and RTG/RMG cranes?

A4:

STS Cranes: Used on the quay to transfer containers between ships and shore.
RTG (Rubber Tyred Gantry) & RMG (Rail Mounted Gantry) Cranes: Used in the container yard for stacking and moving containers.
