I forgot to mention I also have an EQ6 adaptor which can be included with the pier if needed (in preference to the HEQ5 adaptor). The pier also includes a set of castors for wheeling an assembled rig over concrete/pavers.
Pictures added below.
For a description of the pier, see the following website:
