CONNECTION STRUCTURE BETWEEN LIFTING DEVICE AND BODY TO BE LIFTED

摘要

PROBLEM TO BE SOLVED: To enhance working efficiency and stability in a connection structure between a lifting device and a body to be lifted for connecting each side part of the body to be lifted to a pair of lifting bodies lifted on both right and left sides of the body to be lifted.;SOLUTION: A holding means 3 for holding a lifting arm part 20d of each lifting body 20 installed on each side of the body to be lifted 1 comprises a first holding piece 31 swingably connected to a base frame 30 and a second holding piece 32 swingably connected to the first holding piece 31. With the lifting arm part 20d separated from the body to be lifted 1, the first holding piece 31 is positioned outside the vertical projecting space of the lifting art part 20d, the holding part 32d is positioned inside the vertical projecting space of the lifting arm part 20d, and the lifting arm part 20d pushes up the second holding piece 32 by raising the lifting arm part 20d. Since the first holding piece 31 is pulled up through the second holding piece 32, the holding part 31a is brought into contact with the lifting arm part 20d from the lower side.;COPYRIGHT: (C)2009,JPO&INPIT
