Crane Rebuilding vs. New Purchase

by Richard C. Leonard, NORPAC Engineering, Inc, Seattle, United States,



Document Type: Proceeding Paper

Part of: Ports '92

Abstract:

The dimensional and operational features of a container crane which are deemed desirable, if not necessary, in a modern port terminal are discussed and quantified. Some reasons why a crane owner should consider rebuilding older cranes are offered. A schedule of cost ranges for 18 alteration features is included. A discussion of performance and scheduling for various alteration projects is presented, indicating contract duration and crane out-of-service times for specific tasks. Pitfalls and unexpected interrelations between crane rebuilding and port operations and infrastructure are discussed. It is contended, based upon a history of at least 15 container crane rebuilding design and construction monitoring jobs, that a 20-year-old crane can be rebuilt to modern dimensions and speeds for one-half the price and in one-third the calendar time required for the purchase of a new Panamax container crane.
