Lift Technician Course

Lesson 1 • Safety Culture and Regulatory Framework

Introduces safety-first mindset and the regulatory bodies governing elevator work. Establishes compliance awareness required throughout the entire course.

Lesson 2 • Elevator Types and Classifications

Differentiates traction, hydraulic, and machine-room-less systems by application. Builds classification skills needed for all subsequent technical chapters.

Lesson 3 • Technician Roles and Career Paths

Defines installer, adjuster, mechanic, and inspector roles within the trade. Clarifies licensing tiers and apprenticeship progression expectations.

Lesson 1 • DC and AC Circuit Theory

Covers voltage, current, resistance, and power relationships in both circuit types. Provides the theoretical base for understanding elevator control and drive circuits.

Lesson 2 • Electrical Test Instruments

Trains safe use of multimeters, clamp meters, and megohmmeters on elevator circuits. Accurate measurement skills are prerequisite for all diagnostic work ahead.

Lesson 3 • Elevator Schematic Reading

Decodes ladder diagrams, wiring diagrams, and connection schematics used in the field. Schematic literacy is applied in every subsequent troubleshooting chapter.

Lesson 4 • Motors and Transformers

Explains single-phase and three-phase motor operation and transformer voltage ratios. Directly supports understanding of traction machine and control power circuits.

Lesson 1 • Guide Rails and Roller Guides

Covers rail alignment, bracket spacing, and roller guide adjustment procedures. Proper guiding prevents vibration, noise, and safety device misalignment.

Lesson 2 • Traction Machine and Gearbox

Examines geared and gearless machine assemblies, bearings, and lubrication needs. Machine condition affects ride quality, energy use, and brake performance.

Lesson 3 • Hoisting Ropes and Sheaves

Covers wire rope construction, groove profiles, and traction principles. Rope and sheave condition directly determines safe load transfer in traction elevators.

Lesson 4 • Counterweight and Compensation

Explains counterweight sizing, compensation rope/chain use, and balance calculations. Correct balance reduces motor load and improves energy efficiency.

Lesson 1 • Hydraulic Principles and Fluid

Reviews Pascal's Law, flow rate, and pressure relationships in hydraulic circuits. Fluid properties directly affect valve response and cylinder performance.

Lesson 2 • Control Valves and Leveling

Explains up-valve, down-valve, and lowering-valve adjustment for smooth operation. Valve calibration directly determines floor-level accuracy and ride comfort.

Lesson 3 • Hydraulic Safety Devices

Details rupture valves, pressure relief valves, and low-oil protection systems. These devices prevent uncontrolled descent and overpressure damage.

Lesson 4 • Cylinders and Jacks

Covers single-stage, telescoping, and roped-hydraulic cylinder configurations. Cylinder selection and condition affect travel, leveling accuracy, and leak prevention.

Lesson 1 • Microprocessor Control Boards

Explains CPU, memory, and I/O architecture of modern elevator controllers. Board-level knowledge enables parameter programming and fault code interpretation.

Lesson 2 • Variable Frequency Drives

Details VFD operation, motor speed control, and regenerative braking functions. VFD tuning directly affects ride quality, leveling, and energy recovery.

Lesson 3 • Relay and Solid-State Logic

Traces the evolution from relay panels to solid-state logic boards in elevator controls. Understanding relay logic is essential for diagnosing older installed equipment.

Lesson 4 • Dispatching and Group Control

Covers single-car, duplex, and group dispatching algorithms and traffic analysis. Dispatching configuration determines passenger wait times and system efficiency.

Lesson 1 • Hoistway Layout and Surveying

Covers plumb line setup, template use, and tolerance verification for hoistway layout. Accurate layout prevents misalignment of rails, sills, and machine room equipment.

Lesson 2 • Wiring and Final Commissioning

Covers traveling cable routing, controller wiring, and initial run-in procedures. Commissioning confirms all systems operate correctly before acceptance testing begins.

Lesson 3 • Rail and Bracket Installation

Details bracket anchoring, rail splicing, and alignment procedures for car and counterweight rails. Rail quality directly affects ride quality and safety device function.

Lesson 4 • Car and Counterweight Assembly

Guides sling assembly, platform installation, and counterweight frame loading. Proper assembly ensures structural integrity and correct balance factor.

Lesson 1 • Acceptance Testing and Inspection

Guides students through full acceptance test sequences and documentation requirements. Proper test records are required for regulatory approval before public use.

Lesson 2 • Pit and Overhead Safety Features

Reviews pit stop switches, runby clearances, overhead refuge space, and car top guards. These features protect technicians working in confined hoistway spaces.

Lesson 3 • Door Safety and Interlocks

Details door operator mechanics, interlock contacts, and reopening device testing. Door system integrity prevents entrapment and shear hazards at every landing.

Lesson 4 • Buffers and Terminal Devices

Covers oil and spring buffer types, stroke requirements, and terminal slowdown switches. Buffers and terminals prevent overtravel damage at pit and overhead limits.

Lesson 1 • Mechanical Fault Diagnosis

Identifies worn ropes, brake slippage, guide noise, and machine bearing failures. Mechanical diagnosis requires combining visual inspection with measurement data.

Lesson 2 • Systematic Troubleshooting Methods

Applies divide-and-conquer and symptom-based diagnostic logic to elevator faults. A structured approach reduces diagnostic time and prevents misdiagnosis.

Lesson 3 • Preventive Maintenance Programs

Establishes monthly, quarterly, and annual maintenance task schedules for elevators. Structured PM programmes reduce callbacks, extend component life, and ensure compliance.

Lesson 4 • Callback Reduction and Root Cause

Analyses repeat failure patterns to identify root causes and implement permanent fixes. Reducing callbacks improves customer satisfaction and technician productivity.
