Platform and ladder interface for variable slope vibrating screens

摘要

A compact mobile variable angle vibrating screen with climbing and access systems configured to accommodate variable angles and exhibit increased ease and safety for users. The system comprises a stationary ladder and ladder top platform positioned adjacent to a variable angle walkway platform, such that stepping between the platforms is a lateral step when the angle of inclination of the screen is at a halfway point between minimum and maximum inclination.

主权项

1. A variable slope vibrating screen for material processing comprising:
a base frame; a variable position vibrating screen, having a longitudinal axis and being pivotably coupled to said base frame and configured for sorting aggregate by size, said variable position vibrating screen being accessed at variable positions by a walkway platform which remains parallel to the variable position vibrating screen, despite changes in position; a single climbing structure coupled to one of said base frame and said screen for providing access from a lower position to said walkway platform; said single climbing structure being stationary with respect to said base frame; said base frame and said variable position vibrating screen being free of any other climbing structures configured for providing access from a lower position to said walkway platform; and a single climbing structure top platform disposed at the top of said single climbing structure and being coupled to said base frame for providing access from the single climbing structure to said walkway platform; said single climbing structure top platform being stationary with respect to said base frame.
