Abstract
A connector for coupling a plurality of underground roof supports, each roof support including a canopy. The connector includes a guide configured to be coupled to one of the roof supports, and an actuator having a bore and a rod at least partially positioned in the bore. An end of the rod is slidably coupled to the guide. A cable has a first end coupled to the end of the rod and a second end adapted for connection to another of the roof supports.

A connector for coupling a plurality of underground roof supports, each roof support including a canopy, the connector comprising:
- a guide configured to be coupled to one of the roof supports, the one of the roof supports moveable in a direction of advance;
- an actuator including a bore and a rod at least partially positioned in the bore, a first end of the rod being slidably coupled to the guide, a second end of the rod opposite the first end positioned in the bore, an axis of the rod extending through the first end and the second end, the actuator positioned relative to the one of the roof supports such that the axis is oriented transverse to the direction of advance;
- and
- a cable having a first end coupled to the first end of the rod and a second end adapted for connection to another of the roof supports.
A connector for coupling a plurality of underground roof supports, each roof support including a canopy, the connector comprising:
- an actuator including a cylinder including a bore and a rod at least partially positioned in the bore, the actuator adapted for coupling to the canopy of one of the roof supports, each roof support moveable in a direction of advance;
- and
- a cable having a first end coupled to an end of the rod and a second end adapted for connection to another of the other roof supports, extension of the rod relative to the cylinder increasing a tensile force exerted in a lateral direction relative to the direction of advance by the cable on the other roof support.
A canopy for an underground mine roof support, the canopy comprising:
- a canopy body including a surface, the canopy body defining a longitudinal axis, the roof support moveable in a direction of advance along the longitudinal axis;
- an actuator coupled to the surface, the actuator having a cylinder including a bore and a rod at least partially positioned in the bore, the bore extending along a center axis, and the actuator positioned on the canopy body such that the center axis is oriented transverse to the longitudinal axis;
- and
- a cable having a first end coupled to an end of the rod and a second end adapted for connection to another roof support,
- extension of the rod relative to the cylinder increasing a tensile force exerted by the cable on the other roof support.
