• Assemble, install, repair, and maintain elevators, escalators, moving sidewalks, and dumbwaiters, using hand and power tools, and testing devices such as test lamps, ammeters, and voltmeters.
• Test newly installed equipment to ensure that it meets specifications, such as stopping at floors for set amounts of time.
• Locate malfunctions in brakes, motors, switches, and signal and control systems, using test equipment.
• Check that safety regulations and building codes are met, and complete service reports verifying conformance to standards.
• Connect electrical wiring to control panels and electric motors.
• Adjust safety controls, counterweights, door mechanisms, and components such as valves, ratchets, seals, and brake linings.
• Read and interpret blueprints to determine the layout of system components, frameworks, and foundations, and to select installation equipment.
• Inspect wiring connections, control panel hookups, door installations, and alignments and clearances of cars and hoistways to ensure that equipment will operate properly.
• Disassemble defective units, and repair or replace parts such as locks, gears, cables, and electric wiring.
• Maintain log books that detail all repairs and checks performed.
• Participate in additional training to keep skills up to date.
• Attach guide shoes and rollers to minimize the lateral motion of cars as they travel through shafts.
• Connect car frames to counterweights, using steel cables.
• Bolt or weld steel rails to the walls of shafts to guide elevators, working from scaffolding or platforms.
• Assemble elevator cars, installing each car's platform, walls, and doors.
• Install outer doors and door frames at elevator entrances on each floor of a structure.
• Install electrical wires and controls by attaching conduit along shaft walls from floor to floor and pulling plastic-covered wires through the conduit.
• Cut prefabricated sections of framework, rails, and other components to specified dimensions.
