Rocket Crane Service: A Comprehensive Guide

Company History

Rocket Crane Service has its roots dating back to the spring of 1945, founded by Perry B. Hanson. Hanson, who previously worked at Lambert Transfer in Minneapolis, began his venture by purchasing a used auto car tractor and a Fruehauf trailer. He started hauling granite from Cold Spring, MN to Minneapolis, often accompanied by his children, Bernie and Bonnie, on Saturdays.

Following the acquisition of his first new tractor, a 1946 K.B. 11 International with a Tulsa Winch, Hanson expanded the business to include hauling steel culverts, tanks, bar joists, and other building materials across Minnesota. The company’s first cranes were H-3 Bucyrus Erie models equipped with clam shell attachments for digging and setting underground storage tanks.

After Perry Hanson’s untimely death in 1954, his wife Cele and their children took over the operations. By the late 1950s, Rocket had obtained eight state operating authorities, enabling them to haul freight across North Dakota, South Dakota, Minnesota, Kansas, Nebraska, Illinois, Iowa, and Wisconsin. However, by the late 1980s, most of the trucks and accounts were sold, and Rocket Transfer Company was sold in 1983.

A crane makeover to enable rocket science

Crane Makeover to Enable Rocket Science: An In-Depth Guide

Introduction

The German Aerospace Center (DLR), specifically at the Lampoldshausen facilities, is a crucial site for the development of technologies essential for European space travel. One of the key components in this process is the modernization of outdated crane systems to support the testing and development of liquid chemical rocket propulsion systems, such as those used in the Ariane launcher.

The Need for Modernization

The original crane system at the DLR’s Lampoldshausen site, particularly at the height simulation test bench P4, was outdated, dating back to 1964. This crane was critical for moving sensitive components like filters, flaps, and pipes, some weighing over five tons, from truck beds to the building’s door. However, the old system was no longer efficient or safe for the demands of modern rocket science.

Modernization Process

To address these issues, Konecranes undertook a comprehensive modernization of the crane system.

Electrical and Mechanical Upgrades

• The electrical and mechanical systems of the crane were updated to extend its service life and reduce operating costs.
• Frequency-controlled drives replaced the two DC motors on the slewing gear and trolley, allowing for smooth control at optimum speed and precise movement of the system’s parts.

Structural Enhancements

• The crane’s structure was reinforced to handle loads of up to 5 tons with a reach of 15 meters and up to 7.5 tons with a reach of 10.3 meters.
• New protective coatings and a sliding roof were added to shield the control cabinets from extreme weather conditions such as snow, wind, rain, and temperatures ranging from -5°C to +40°C.

Safety Improvements

• Non-slip sheets were installed on the bars and staircases, and a new railing was added to enhance safety.
• These modifications aimed to ensure the crane could endure harsh weather conditions and maintain high safety standards.

Operational Capabilities

The modernized crane system significantly improved the operational capabilities at the DLR’s Lampoldshausen site.

Load Handling

• The crane can now lift and move components weighing up to 5 tons at a reach of 15 meters and up to 7.5 tons at a reach of 10.3 meters.
• This enhanced capacity is crucial for the efficient transportation of heavy and sensitive components.

Weather Resistance

• The new protective measures, including the sliding roof and protective coatings, ensure the crane can operate reliably under various weather conditions.
• This is particularly important given the exposure of the crane on the roof of the P4 building.

Impact on Rocket Science

The modernization of the crane system has a direct impact on the development and testing of rocket propulsion systems.

Testing Conditions

• The height simulation test bench P4, where the crane is used, simulates spacelike conditions for testing rocket engines.
• The precise and safe movement of components by the modernized crane is essential for these tests.

European Space Strategy

• The Ariane program, which includes the Ariane 5 rocket, is a cornerstone of European space strategy.
• Reliable and efficient ground support systems, such as the modernized crane, are vital for the success of these launch vehicles.

Conclusion

The modernization of the crane system at the DLR’s Lampoldshausen site is a testament to the importance of upgrading infrastructure to support cutting-edge scientific and technological endeavors. This project highlights how tailored upgrades can extend the service life of critical equipment, enhance safety, and improve operational efficiency, ultimately contributing to the advancement of rocket science and European space exploration.
