Abstract
An adustable cap unit for a mine support frame including a main cap, an adjustable cap connected to the main cap with a hinge-type connection, an adjusting cylinder mechanism extending within the widths of the main cap and the adjustable cap, and a guide for guiding a portion of the adjusting cylinder mechanism in a restrictive manner. The adjusting cylinder mechanism is provided either in the main cap or in the adjustable cap and an end portion of the adjusting cylinder mechanism is hinged to a bearing member provided at the bottom edges of the main cap or the adjustable cap adjacent the hinge-type connection. The adjustable cap unit can be used in extremely small seam thicknesses of as little as approximately 500 mm, while the contact pressure available at the front end of the adjustable cap is sufficient.
