ABSTRACT:
An extensible and retractable telescopic chute for delivery of bulk materials includes a plurality of nestable chute segments, namely, an uppermost segment adapted to be attached to the discharge end of a bulk material handling machine, a lowermost chute segment and a plurality of intermediate chute segments therebetween. A yoke member surrounds the lowermost chute segment and is attached thereto. A pair of sheave support posts upwardly extend on opposed sides of the yoke member. Each of the posts carry a rotatable sheave wheel which are respectively adapted to operably engage a wire rope of the hoist mechanism of the material handling machine. The yoke member bears the loading weight of the nested chute segments as the telescopic chute is retracted so as to avoid sidewall deformation of the lowermost segment. The vertically extending sheave support posts locate the sheave wheels well above a center of gravity of the nested chute segments to stabilize the chute assembly above a vertical axis.
