Elevator guide rails are components of elevator systems that define the path along which the elevators ride. An elevator should not be expected to operate regularly and safely on guide rails that do not possess the minimum quality standards and that are not installed properly. Data receivers which transmit to the control system the information about the position of elevators, doors, door locks and safety brakes are designed on the assumption that guide rails will follow certain paths. Guide rails are manufactured in fully equipped factories possessing high-quality measurement systems. However, guide rails manufactured in these factories may be installed into poorly built elevator wells at construction sites. The quality level expected of elevators can be achieved only if the manufacturing and installing processes are coordinated successfully. Consequently, we have allocated more room for practical information herein which might be handy for a field technician rather than information on manufacturing processes and calculation methods and techniques.
