The invention mentions to the complex of concrete spreader (A) and the crane
tower (B), including:
concrete pump (1), concrete tank (2), to be placed on the ground, sections of
tremie pipes (4), (11), (20) and
ball bearing (23) are fitted inside the
tower sections (12) for use those sections (12) to support
tremie pipe sections (11) to stand steadily in the crane
tower (B), steel sections (27), (29) are fitted in the lower side of suspension arm (25) and
tremie pipe sections (37a), (37b), (37c), (37d) and (37e) are inter-assembled at the lower side of
steel bar (29), and
steel bar (29) is used for making a guide way for these sleeve sections moving, the tremie
pipe sections (77), (82), (84) are fitted with
ball bearing (83) and steel hoop (85), the latch structure (88) is fitted in the front and back head of these sleeve sections, the
tensile structure of moving sections (37e), (37d), (37c) and (37b) is included an electrical hoist (107), to be fitted into suspension arm (25), cable branches (108a), pulleys (110), (111), (112), (113) are fitted in suspension arm (25) for pulling of sleeve sections (37e), (37d), (37c) and (37b) to be lengthened or shortened at concrete positions, the slanting structure of sections (82), (84) is included steel section (114),
oil pump (129),
oil tank (133) for
piston cylinder (122) to push, pull sections (82), (84) to be inclined backward and ahead at the shortest and longest concrete reach.
