	Operationally, consideration should be given to the speed of the machine, any client requirements in the area, and also to how the machine operates. Modern machines have the ability to slow down and stop after periods of non-use and have a traffic light and sensor arrangement fitted to each end to start-up the machine when approached by a user. The timings and settings for this operation need to be agreed during the design stage as the number of starts and stops each machine can make in an hour has a bearing on the duty of the machine and therefore size, loadings and cost. Also to consider here is that of the emergency stop arrangements, if the machine is to be installed in a location that is not supervised (railway station, shopping centre perhaps) then there are options for automatic re-start in the event of an emergency stop activation. These systems are complex and costly but again need to be defined during design to ensure the machine is designed in line with the client requirements.

−	Robustness is another consideration especially for machines fitted in harsh areas such as railway stations, car parks and shopping centres. These units need to be of a suitable construction to withstand the rigours and high volume of users associated with the installation and often can include the ability to withstand the impact of inclement weather (rain, wind, etc.).	+	Robustness is another consideration especially for machines fitted in harsh areas such as railway stations, car parks and shopping centres.

	* Tank switches: if the safety switches on the floor plates at each end are not set correctly then this can cause the machine to cut out, this happens especially in situations where users are using trollies or suitcases and the additional weight at the entry or exit points causes the electrical limit switch to ‘bounce’ and thus stop the machine.		* Tank switches: if the safety switches on the floor plates at each end are not set correctly then this can cause the machine to cut out, this happens especially in situations where users are using trollies or suitcases and the additional weight at the entry or exit points causes the electrical limit switch to ‘bounce’ and thus stop the machine.

	For new installations, the architect is generally accountable for ensuring the building has been designed with adequate consideration to the fitment and placement of the lift shaft, whether it be steel or concrete construction. It’s imperative that the architect engages with the chosen lift supplier to agree and include the lift shaft dimension and requirements. To support this activity, it is the lift supplier’s role to provide lift shaft layout drawings for the architect to incorporate into the overall building design (see Figure 3).
