Abstract

Swing type construction machinery, wherein a lower side lateral plate (23) and an upper side lateral plate (24) are provided between a left vertical plate (19) and a right vertical plate (20) of a swing frame (17), a hose inserting hole (26) is provided in the right vertical plate (20) on the upper surface side of the upper side lateral plate (24), and a soil and sand passage (25) through which to pass sand and soil falling from the upper side is formed between the lower side lateral plate (23) and the upper side lateral plate (24), whereby a hydraulic hose (37) comprising a hydraulic hose (37E) for offset, a hydraulic hose (37F) for bucket, and a hydraulic hose (37G) for arm is taken out from the hose inserting hole (26) for easier handling of the hydraulic hose (37), and the soil and sand passage (25) allows the fallen soil and sand to be discharged to the outside of an upper swing structure (2) to prevent soil and sand from accumulating around the hydraulic hose (37).
