Assemble, install, repair, or maintain electric or hydraulic freight or passenger elevators, escalators, or dumbwaiters.

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

Mechanical -- Knowledge of machines and tools, including their designs, uses, repair, and maintenance. Building and Construction -- Knowledge of materials, methods, and the tools involved in the construction or repair of houses, buildings, or other structures such as highways and roads. Engineering and Technology -- Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services. Se

Repairing -- Repairing machines or systems using the needed tools. Installation -- Installing equipment, machines, wiring, or programs to meet specifications. Quality Control Analysis -- Conducting tests and inspections of products, services, or processes to evaluate quality or performance. Equipment Maintenance -- Performing routine maintenance on equipment and determining when and what kind of maintenance is needed. Troubleshooting -- Determining causes of operating errors and deciding what to do about it. Operation Monitoring -- Watching gauges, dials, or other indicators to make sure a machine is working properly. Equipment Selection -- Determining the kind of tools and equipment needed to do a job. Operation and Control -- Controlling operations of equipment or systems. Reading Comprehension -- Understanding written sentences and paragraphs in work related documents. Judgment and Decision Making -- Considering the relative costs and benefits of potential actions to choose the most appropriate one.

Wrist-Finger Speed -- The ability to make fast, simple, repeated movements of the fingers, hands, and wrists. Deductive Reasoning -- The ability to apply general rules to specific problems to produce answers that make sense. Problem Sensitivity -- The ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem. Near Vision -- The ability to see details at close range (within a few feet of the observer). Manual Dexterity -- The ability to quickly move your hand, your hand together with your arm, or your two hands to grasp, manipulate, or assemble objects. Information Ordering -- The ability to arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations).

Repairing and Maintaining Mechanical Equipment -- Servicing, repairing, adjusting, and testing machines, devices, moving parts, and equipment that operate primarily on the basis of mechanical (not electronic) principles. Inspecting Equipment, Structures, or Material -- Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects. Handling and Moving Objects -- Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things. Getting Information -- Observing, receiving, and otherwise obtaining information from all relevant sources. Repairing and Maintaining Electronic Equipment -- Servicing, repairing, calibrating, regulating, fine-tuning, or testing machines, devices, and equipment that operate primarily on the basis of electrical or electronic (not mechanical) principles. Performing General Physical Activities -- Performing physical activities that require considerable use of your arms and legs and moving your whole body, such as climbing, lifting, balancing, walking, stooping, and handling of materials. Evaluating Information to Determine Compliance with Standards -- Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards. Identifying Objects, Actions, and Events -- Identifying information by categorizing, estimating, recognizing differences or similarities, and detecting changes in circumstances or events. Controlling Machines and Processes -- Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles). Documenting/Recording Information -- Entering, transcribing, recording, storing, or maintaining information in written or electronic/magnetic form.
