A connection device for suspending a monorail beam includes a top anchor integrated with or attachable to a roof bolt and a clamping device for connection to the monorail beam. The clamping device has a housing attachable to the monorail beam. The housing includes a central recess with an opening configured such that the top anchor is movable into and out of the central recess along a first axis through the opening. The clamping device has a plurality of locking members radially movable into and out of the central recess with respect to the first axis between an inner locking position in which the locking members prevent the top anchor from moving out of the central recess, and an outer open position in which the top anchor is free to move past the locking members, each respective locking member being provided in a respective radial guide recess of the housing.

An assembly and method for removably installing a round linear track to a floor is provided. The assembly includes a track guide having a plurality of curved bearing surfaces to support a round track segment and a clamp to removably capture the round track in the track guide. The method includes placing a segment of round track on a lead portion of the track guide; moving the segment of track into a supporting portion of the track guide; and capturing the segment of round track in the track guide with a clamp.
