PROBLEM TO BE SOLVED: To provide a device capable of efficiently bringing a long material into a narrow pit without subdividing the long material. SOLUTION: A front end part of a truck body 2 loaded with rails A is provided with landing wheels 26, 27, the truck body 2 lifted down into the pit 100 is landed on rails 3 by the landing wheels 26, 27, an attitude of the truck body 2 is gradually approximated to a horizontal state with advancing the front end part of the truck body 2 on the rails 3 by the landing wheels 26, 27, and travel wheels 26, 27 of the truck body 2 are placed on the rails 3. Otherwise, a hanger 60 for hanging a cast iron pipe P is suspended by a suspension mechanism 70 at different two points along the longitudinal direction such that a tilt attitude of the hanger 60 can be freely adjusted. In the latter method, a chain 71 cannot function in case of the narrow pit 100. For the purpose of solving this problem, the former method is devised.
