Abstract

PURPOSE: To lighten a device for moving a crane operating room by supporting the operating room via a linkage composed of the combination of movable links and parallel links and telescoping the room by means of the extension and contraction of the linkage.
CONSTITUTION: When a telescoping unit 13 is driven, a crane operating room 2 is extended or retracted. Links 10, 11, 12 are connected via pins 17 to operate any of axial and tensile forces thereat. Parallelogram linkages of the links 10 are elevationally combined so that the room 2 is balanced at any position. As a result, the unit 13 may be of a mechanism for generating only a force corresponding to the frictional force produced by the friction at the pin connections of the links to thereby lighten the mechanism. The distance between the crane body 1 and the room 2 can be freely selected merely by increasing the number of the links.
