Evaluation of Selected Commercial Construction Equipment for Bomb Damage Repair

摘要

Three pieces of commercial equipment, a loader, an excavator, and a combination loader/backhoe, were evaluated for use in rapid repair of damaged airfields. The equipment was evaluated for their ability to remove damaged, upheaved concrete from around bomb craters. The actual force required to remove damaged concrete was also measured on an explosively formed crater. The force required was found to be in the 20,000-25,000 lb range. Of the three pieces of equipment evaluated the most capable was the large front-end loader; however, it was found to be too large for the smaller craters. The hydraulic excavator would be the best machine for the job if it had at least 25,000 pounds of breakout force.
