Inquiry (采购产品): help please! I know this is a strange request-but having trouble finding info anywhere else. This is for a school science project which includes an explanation of how a hydraulic ladder works (the technical side or mechanics of it). If you have any information or diagrams that you can send to me I would really appreciate it. Thank you again, Avonna **** Hidden Message ***** Avonna Formalejo 9825 N70th St. 220 Scottsdale, AZ 85253 USA Company: No company Phone: 480 991 7701 Fax: 480 361 3624 E-mail: vallon1@aol.com **** Hidden Message ***** vallon1@aol.com
