The system consists of two pairs of travellers linked in tandem that can be separated, if necessary, into independent units. These are fitted to a metal track rail which allows the travellers to glide along it. There is the option of having more than one traveller on the rail. The rails and travellers should be maintained and cleaned to prevent any damage of the system, and furthermore any accident.
