Abstract
A mounting assembly is provided for mounting a sheave roller to a ladder-type cable tray. The cable cables can be laid on the cable tray for routing through a building. The mounting assembly includes first and second housing parts which are moveable relative to each other. The housing parts are attached to respective rungs of the cable tray. A lock prevents the relative movement of the housing parts relative to each other once the mounting assembly is engaged with the cable tray. The sheave roller is rotatably attached to the one housing part. This quickly and easily installs the sheave roller on the cable tray.
Claims24
In combination, a mounting assembly and a sheave roller, the mounting assembly configured to attach the sheave roller to a ladder-type cable tray having a plurality of spaced apart rungs, the combination comprising:
- the sheave roller;
- and
- the mounting assembly comprising a first housing part, said sheave roller being rotatably attached to said first housing part, said first housing part comprising a base and an arm extending from said base, said first housing part capable of being engaged with a rung of the cable tray, a second housing part configured to be slideable relative to said first housing part, said second housing part comprising a base and an arm extending from said base of the second housing part, said second housing part capable of being engaged with another one of the rungs of the cable tray, and a lock capable of being engaged with the first and second housing parts thereby preventing all movement between the first and second housing parts and capable of being disengaged to allow sliding movement between the first and second housing parts.
A combination comprising:
- a cable tray comprising a pair of rails and a plurality of spaced apart rungs extending between said rails, each rung defining a first surface upon which cables can be laid for routing through a building, each rung having a second surface which is opposite to the first surface;
- a sheave roller;
- a mounting assembly configured to mount the sheave roller onto the rungs of the cable tray, said mounting assembly comprising a first housing part, said sheave roller rotatably attached to said first housing part, said first housing part capable being engaged with a rung of the cable tray, a second housing part configured to be slideable relative to said first housing part, said second housing part capable of being engaged with another one of the rungs of the cable tray, and a lock capable of being engaged with the first and second housing parts thereby preventing all movement between the first and second housing parts and capable of being disengaged to allow sliding movement between the first and second housing parts.
In combination, a mounting assembly and a sheave roller, the mounting assembly configured to attach the sheave roller to a ladder-type cable tray having a plurality of spaced apart rungs, the combination comprising:
- the sheave roller;
- and
- the mounting assembly comprising a first housing part, the sheave roller being rotatably attached to the first housing part, the first housing part comprising a planar base having an upper surface and a lower surface, an arm extending from the lower surface of the base, and an aperture provided through the base, the first housing part capable of being engaged with a rung of the cable tray, a second housing part configured to be slideable relative to the first housing part, the second housing part comprising a base having an upper surface and a lower surface and an arm extending from the lower surface of the base of the second housing part, the lower surface of the base of the second housing part being positioned above the upper surface of the base of the first housing part, the second housing part capable of being engaged with another one of the rungs of the cable tray, and a lock capable of being engaged through the aperture and with the second housing part thereby preventing the relative movement of the first and second housing parts and capable of being disengaged to allow the relative movement of the first and second housing parts.
