A tilting device for a cabin of construction machinery is provided to make the tilting movement of a cabin possible without a separate hydraulic or pneumatic driving device, to improve safety with a safety lever by preventing a cabin from dropping even if a tilting device gets out of order and to improve the ascending and descending speed of a cabin, and to improve durability by supplying lubricating oil to a screw thread of a screw. A tilting device for a cabin of construction machinery, for tilting a cabin installed on a frame to be able to tilt, comprises a screw(340) installed to the cabin to be rotatable, a moving member(360) installed on the cabin to make a rectilinear motion possible, and coupled to the screw to make a rectilinear motion in one direction or the other direction according to the rotating direction of the screw, a rotation lever(370) whose one end is connected on the frame to be rotatable and the other end is connected to the moving member to be rotatable to ascend and to descend the cabin according to the moving direction of the moving member, a guide shaft(350) installed parallel to the screw on the cabin and coupled to the moving member to guide the rectilinear motion of the moving member, a hanger pin(380b) installed on the frame, a safety bar(380) whose one end is connected to the cabin to be rotatable and the other end is provided with a hanger portion(380a) to insert the hanger pin selectively to support the cabin to the frame, and an oil feed nipple formed on the moving member to supply lubricating oil to the screw. |
