Question 1: Could you please tell me the OEM / Crane Manufacturer for this crane and also the Manufacturer’s Crane Serial Number? (This information is typically found on the crane nameplate displayed on the crane sign or found in the O&M Manual).

Answer: The Manufacturer is Crane Hoist Engineering Corp., Los Angeles California. The crane was designed specifically for ERDC in 1960 and has a Specification No. of 1656 from the Manufacturer. The crane does not have one specific serial number, but rather each individual part has a serial number from the manufacturer which Crane Hoist Engineering Corp. sourced the part from.

Over the years, as the crane was serviced and repaired, parts have been replaced with new ones without being recorded. Additionally, some of the original serial numbers have been lost and or damaged beyond recognition during regular use of the crane.
