Design of Crane Boom Dolley
Miscellaneous Lifting Devices
A local crane company needed a unique design for a crane boom dolly that allowed for storage of the crane's counterweights. A design requirement was to still allow easy access during rig-up.
DAIR designed and certified a number of adjustable lifting devices for handling a range of valve bodies in a production environment.
Design Review of Heavy Haul Trailer
Design Review of Trailerized Substructure
DAIR performed a Design Review of a heavy haul trailer with a capacity of 300,000 lbs.to be used in the transportation of transformers as well as large vessels. The project brought vessels from Lewiston, Washington to Grande Prairie, Alberta
A Design Review was performed and an API Design Binder was prepared for a company pursuing API Certification for their fabrication shop.
We have extensive experience with equipment upgrades and modifications in both machining and fabrication, which translates into upgrades that can be easily incorporated into existing designs.
We can measure and analyze the equipment to determine what has to be reinforced or replaced to meet Code requirements. We will provide a concise and complete set of fabrication and installation drawings.
We will perform an inspection of the modifications and issue a certification for the equipment at the upgraded capacity.
With backgrounds ranging from textiles lasercutters to ultralights to steel building connections to computer mass storage devices, we have a wide background of problem solving. If you have had a challenge that you have not yet overcome and need some engineering and fabrication assistance, we may be able to help.
Please contact us so that we can find out more about your company and how we can help you.
