A building containing one or more mechanical elevators, especí- ally a warehouse for the storage of grain; a hoisting apparatus; a lift; a car or cage for lifting and lowering passengers or freight in a hoistway. Cent. Dict. An elevator is a platform, car, cab, or cage, propelled vertically in a hoistway, hatchway, or shaft, by cables, moved gen- erally by either hydraulic pressure, elec- tricity, steam, or compressed air. In its upward and downward course it is usually conducted by a motorman on board, who stops and starts it at will. In comparatively recent years the elevator has come into gen- eral use in the factory, mill, warehouse, mercantile and office building, and apart- ment house. It may be constructed and used for the carriage of passengers, or freight, or both. 10 A. & E. Ency. 2nd ed., 945. A passenger elevator is not a device dan- gerous, to life, per se; 90 Wis. 497. A landlord who runs an elevator for the use of his tenants and their visitors thereby becomes a common carrier; 41 Minn. 207; and is charged with the highest degree of care which human foresight can suggest, both as to the machinery and the conduct of his servants; 54 Fed. Rep. 637; 80 Cal. 595. A carrier of passengers by elevator is not an insurer, but is required to exercise the highest degree of care; 62 Fed. Rep. 139; 114 N. Y. 812; 159 Mass. 26. In con- structing an elevator the utmost care must be exercised; 41 Minn. 209; competent workmen must be employed and suitable material used; 20 Col. 292. In case of a casualty, it is not enough to show that the elevator is one of a kind in ordinary use; 50 Mo. 390; 136 III. 170. But the absence of safety appliances is said not to be con- clusive evidence of negligence: 142 Mass. 83. An elevator is not supposed to be a place of danger, to be approached with great caution; but when the door is opened a passenger may enter it without stopping to make a special examination; 114 N. Y. 318. One who habitually rides on a freight elevator, in contravention of a posted no- tice, does so at his own risk; 156 Mass. 511. See as to injury to passengers, 25 L. R. A. 33, as to freight id. 34. The business of elevating grain is a busi- ness charged with a public interest, and those who carry it on occupy a relation to the community analogous to that of a com- mon carrier, and may be controlled by pub- lic legislation for the common good; Munn. v. Illinois, 94 U. S. 113; 143 U. S. 517. For liability of owners of buildings for accidents at elevator shafts, see 9 Lawy. Rep. Ann. 640, n. See, generally, Webb, Elevators; L. R. 12 Q. B. Div. 30. Operators of Elevators. The proprietor or operator of an elevator is a carrier. Id.; 62 Fed. Rep. 139, et al. A carrier by elevator of passengers, is not an insurer, but is required to exercise the highest degree of care in everything calculated to insure the safety of his passengers. There is no distine- tion in law between the duties and liabilities of a carrier by elevator and one by railroad. Id.
