Carpenter Crane has designed and built test weights for clean room testing as well as standard test weights. Clean room test weights need to meet the cleanliness requirements for the environment. Our weights come with casters and a handle for easy transport on site. Many of the test weights available are left from the Naval Shipyard where we are located.
Many of the components CCD builds requires a pull test to verify the capacity of the part. Many times pulling a part to destruction tells if the required safety factor has been designed into the part. In our facility, there is a pull tested that will pull to 300,000 lbs. At another Carpenter location we can pull to a load of 1.2 million pounds.
Many of the components and assemblies that we design need to meet a specific level of cleanliness. In our clean room we have an isolation chamber specifically for particle testing giving us a zero back ground environment for testing.
Lifting Beam Testing
Lifting beams are one of the many under the hook devises that CCH builds. Being part of The Carpenter Group gives a lot of opportunity to design and build lifting beams for the other companies in the group. CCH found a need for a tester to easily test the beams we build. CCH designed a beam tester to test beams to 25 ton and 30’ long.
Samsung Austin Semiconductor
Samsung need a crane to service the equipment in a more efficient way. CCH designed a crane to mount onto their equipment. The crane was to operate in a class 10 environment. CCH used a crane made by one of our suppliers. We had to first test to see how clean the crane was. We then needed to modify the crane to make it clean enough to meet the requirement. Once the changes were made we then were able to verify that the crane meets the clean room requirement.
