Category: Cranes: Procurement and New Development

This presentation discusses Liftech’s structural engineering design services for a variety of colossal cranes and includes some of the basic design issues associated with these cranes.

This presentation discusses single hoist tandem 40 (SHT40) and dual hoist tandem 40 (DHT40) cranes. These cranes pick up two or more containers with a single trolley running on a conventional runway.

This presentation discusses two variations of Floaterm concepts: midstream and ship-in-a-slip operations. Engineering calculations have been prepared to verify the technical feasibility of the concepts, but are not included here.

This paper provides port owners with information to be considered before purchasing DHT40 cranes.

This presentation discusses emerging tandem 40 dual hoist systems being developed to reduce the vessel time at the berth, and addresses some considerations at the crane-yard interface.

This presentation discusses two of the many systems being developed to reduce the vessel berth time—the use of Tandem 40 dual hoist cranes and Floaterm, a scheme to service vessels midstream.

This presentation examines the environmental impact of the ever-increasing size of dockside container cranes on neighboring communities and presents potential solutions to reduce the impact.

Jumbo Cranes—cranes with outreaches of 60 meters or more, lifts above the crane rail of 46 meters, and capacities of 60, 80, 100, and 120 tons—are already built or being built. Why?

This paper discusses the factors affecting lateral boom vibration, what vibrations are acceptable, and provides recommendations to reduce lateral boom vibrations.

This presentation examines some crane types and sizes, the visual impact study for the Port of Los Angeles, and, finally, the proposed 22-wide low profile crane.
