摘要： A mine roof support has a leg alignment device in the form of a resilient steady which extends from a baseplate and is connected at its upper end with the leg through a variable length device. The variable length device is an eccentric in the form of a pin on a plate rotatable and lockable on the top of the steady. The pin is connected by a connecting rod to the leg.

摘要： A cradle for placing a support in a mine. The cradle includes a housing for holding the mine support. The cradle includes an arm mechanism rotatably attached to the housing which has an open position that allows the support to enter the housing and a closed position which prevents the support from leaving the housing. The cradle includes an attachment mechanism connected to the housing for rotatably attaching the housing to a platform of a mechanism for moving the mine support. The attachment mechanism maintains the housing in the horizontal position or a vertical position. A method for placing a support in a mine. The method includes the steps of moving a support from a platform to a cradle. Then there is the step of rotating the cradle until the support is in a vertical position relative to ground. Next there is the step of placing the support on the ground. Then there is the step of separating the support from the cradle. Next there is the step of tensioning the support with the mine roof.

摘要： An arrangement for erecting a columnar supporting element of a hardenable flowable material, for a roof of an underground excavation, has a hollow casing for filling with a hardenable flowable material and is composed of two telescopable casing portions each composed of two open-end semi-circular sections, an element for holding the upper casing portion in contact with the roof of an underground excavation and arranged adjacent to the casing, and elements for connecting the semi-circular sections of at least the lower prop casing portions with one another so as to be pivotable about a longitudinal pivot axis which is parallel to the longitudinal axis of the prop casing, and locking the same with one another.
