Abstract
A cabinet assembly is disclosed. The cabinet assembly includes a scissors lift mountable to a utility pole and including a plurality of linkages. The scissors lift is moveable between extended and retracted positions. The scissors lift includes a drive mechanism interfaced with the linkages and configured to move the scissors lift between the extended and retracted positions. The cabinet assembly further includes a cabinet mounted to the scissors lift and moveable between raised and lowered positions.
Claims18
A cabinet assembly comprising:
- (a) a scissors lift mountable to a utility pole and moveable between extended and retracted positions, the scissors lift including:
- a plurality of linkages;
- a plurality of guide blocks located along the plurality of linkages;
- a sleeve fixedly attached to the cabinet and configured to slideably attach to one or more of the guide blocks;
- and
- a drive mechanism interfaced with the plurality of linkages and configured to move the scissors lift between the extended and retracted positions;
- and
- (b) a cabinet mounted to the scissors lift and moveable between raised and lowered positions.
A telecommunications cabinet assembly comprising:
- (a) a scissors lift capable of being fastened to a utility pole at a raised position and including a plurality of linkages, a plurality of guide blocks located along the plurality of linkages, a sleeve fixedly attached to the telecommunications cabinet and configured to slidably attach to one or more of the guide blocks, and a drive mechanism, the scissors lift oriented downwardly and moveable between extended and retracted positions;
- (b) a telecommunications cabinet mounted to the scissors lift and moveable between the raised position and a lowered position by extending the scissors lift from the retracted position to the extended position.
A method of accessing a telecommunications cabinet, the method comprising:
- extending a scissors lift to move a telecommunications cabinet from a raised position to a lowered position, the scissors lift including a plurality of linkages, a plurality of guide blocks located along the plurality of linkages, and a sleeve fixedly attached to the telecommunications cabinet and configured to slidably attach to one or more of the guide blocks;
- accessing the interior of the telecommunications cabinet;
- retracting the scissors lift to move the telecommunications cabinet from the lowered position to the raised position.
A scissors lift for a telecommunications cabinet, comprising:
- (a) a mount mountable to a utility pole;
- (b) a plurality of scissors linkages;
- (c) a drive mechanism interfaced with the plurality of scissors linkages and configured to move the linkages between extended and retracted positions;
- wherein the drive mechanism includes a screw drive engageable by a drive bar and a plurality of support bands affixed to the plurality of scissors linkages, wherein the screw drive is oriented parallel to a direction of extension of the scissors linkages and one of the support bands includes a threaded interior configured to interlock with the screw drive, the remaining support bands having an unthreaded interior and sized to extend onto the drive bar when the linkages are in the extended position.
