Inquiry (采购产品): Screw Jacks We have a 700 man camp located in the Canadian Arctic. The units are ATCO trailers that require leveling at least twice per year. Presently, they are leveled by shimming them between the frames and the blocks they are sitting on. This is time consuming and presents a number of safety risks. I am looking for some sort of manually operated screw jacks to replace the current system. The trailers weigh 30,000 lbs each and must be jacked in 6 locations each. **** Hidden Message ***** Terry Bradburn PO Box 1046, 107 Berry St. Yellowknife, NT X1A 2P8 CAN Company: Diavik Diamond Mines Inc Title: Project Manager Phone: 867-766-5452 E-mail: terry.bradburn@diavik.com **** Hidden Message ***** terry.bradburn@diavik.com
