Joint Army/Navy Rider Block Tagline System Test. Preliminary Report.

摘要

The objectives of the Rider Block Tagline Test were to: demonstrate the feasibility of the rider block tagline concept as an effective means of load control in a dynamic environment; obtain engineering data for evaluation of the rider block tagline system (RBTS) design and operational characteristics; and evaluate the capability of the RBTS to enhance cargo operations at sea. The prototype RBTS was installed on a Bucyrus-Erie BE-38B crane and was tested under conditions of limited sea state. Of particular significance was the demonstration that the RBTS can be retrofitted on a standard commercially available, mobile crane. Stress in the boom due to ride loading, a major limiting factor in the use of cranes afloat, were significantly reduced by the RBTS as indicated by strain gage data, and the RBTS provided an increased level of load control in a dynamic environment. It is recommended that a full scale RBTS be built, installed and tested on a container capable crane. (Author)
