1.2SUMMARY

Service elevators are elevators that are used both for passenger service and for moving freight. They are passenger elevators, even though car finishes may be similar to freight elevators. The term "freight elevator" is defined in ASMEA17.1/CSAB44 to mean elevators used primarily for carrying freight and inaccessible to the general public. ASMEA17.1/CSAB44 does not have the same requirements for freight elevators as for passenger elevators, so using the proper terminology is important.
