Abstract
A drilling and bolting rig for performing drilling and bolting operations. The drilling and bolting rig includes a magazine for storing a consumable, a feed supporting a drill head for movement relative to a work surface, and a loader configured to retrieve the consumable from the magazine and load the consumable into the drill head. The loader includes an arm operable to engage the consumable. The arm is supported for both rotational and translational movement.
Claims13
A drilling and bolting rig comprising:
- a drill head for driving a consumable into a work surface;
- a feed supporting the drill head for movement relative to the work surface;
- and
- a hydraulic circuit including,
- at least one auxiliary flow control valve for selectively controlling flow of pressurized fluid to one of a first hydraulic component and a second hydraulic component, and
- a main flow control valve for controlling flow of pressurized fluid to the at least one auxiliary flow control valve, the at least one auxiliary flow control valve and the main flow control valve being movable between a first configuration and a second configuration, pressurized fluid being provided to operate the first hydraulic component while the at least one auxiliary flow control valve and the main flow control valve are in the first configuration, pressurized fluid being provided to operate the second hydraulic component while the at least one auxiliary flow control valve and the main flow control valve are in the second configuration.
