What reading level is Elevator Service book?
To quickly assess the difficulty of the text, read a short excerpt:
The time occupied by this process is affected by similar condi- tions of alert operation, and of cooperation on the part of pas- sengers as on upper landings ; and it is still more influenced by the proportions of the door-opening through which, at this floor, not merely one or two, but all the passengers must pass both in and out.
Heavy doors, narrow entrances, unfavorably shaped cars, and excessive loads in the car, will retard the ingress and egress of passengers at this stage of the work of... the elevator.
Observations have been made showing that under circum- stances, all of which are favorable, a load of passengers can make their exit at the rate of %o of one second per person, and a new load can enter and take their places in the car at the rate of %o of one second per person, but these figures will be in- creased to double the time when all the circumstances are ad- verse.
The conditions are so rarely fully favorable that a conserva- tive average of two seconds per passenger, that is, iVi second for ingress, and % of one second for egress for each person, should be made, and to this should be made, for the operation of opening and closing the gates at the starting floor, an addi- tion of four seconds.
