Lift installation is a complex process that includes construction, mechanical, electrical, and commissioning works, after which the equipment undergoes inspection, testing, and technical examination.
Installing a lift in an apartment building requires coordinated work between the designer, general contractor, installation company, equipment supplier, and the client’s technical supervision team.
Errors during lift installation can lead not only to noise, vibration, and uneven cabin movement, but also to improper operation of doors, braking systems, and safety devices.
Lift installation from scratch does not begin with installing the cabin. The first stage is checking the design documentation and confirming that the construction works are ready for installation.
Before work begins, it is necessary to verify that the shaft, pit, openings, embedded elements, machine room, and power supply comply with the design requirements and the manufacturer’s documentation.
The installation of lift equipment includes fitting the guide rails, shaft doors, cabin, counterweight, drive system, ropes, overspeed governor, electrical equipment, and control system. After mechanical assembly, lift adjustment, electrical circuit checks, and commissioning works are carried out.
Preparation of the lift shaft directly affects the quality of the subsequent installation. Before handing over the work area, specialists check the dimensions and geometry of the shaft, wall verticality, position of openings, depth and condition of the pit, location of embedded elements, and safe access for installers.
Construction of the lift shaft forms part of the building works, so its parameters must comply with the approved design.
If the shaft has already been constructed, its geometry is checked and the actual dimensions are compared with the equipment supplier’s requirements. Even small deviations can be critical, as they may complicate alignment of the lift guide rails, installation of doors, and achievement of the required clearances.
Lift shaft requirements depend on the equipment model, load capacity, travel speed, drive system, and intended use of the building.
The lift installation procedure is determined by the Work Execution Plan and the manufacturer’s instructions, but usually includes six stages:
The lift installation method must ensure the precise positioning of all components relative to each other. For example, installation of lift guide rails requires checking their vertical alignment and the distance between working surfaces, while installation of shaft doors requires checking levels, clearances, interlocks, and alignment with cabin stopping positions.
Passenger lift installation and freight lift installation follow a similar sequence, but the requirements for the equipment differ.
When installing a freight lift, the rated load capacity, cabin and doorway dimensions, type of goods being transported, and expected intensity of operation must be taken into account.
Installing a lift in an apartment building requires particular attention to stopping accuracy, door operation, noise levels, dispatcher communication, and the possibility of safe passenger evacuation.
Regardless of the type of equipment, lift installation must comply with the design solutions, manufacturer’s documentation, and applicable safety requirements.
Quality control during lift installation should be carried out at each stage rather than only after all works have been completed.
At the early stages, specialists check the construction readiness of the shaft, followed by the position of the guide rails, quality of fixings, installation of the cabin, counterweight, doors, and machinery.
After the electrical systems are connected, grounding, interlocks, lighting, communication, controls, and lift operation under normal and emergency conditions are checked.
Technical supervision of lift installation helps the client independently verify the quality of the installation contractor’s work, confirm that the installed equipment corresponds to the certificates, and ensure that identified deficiencies are corrected.
General technical supervision in construction also checks whether the construction part of the lift shaft complies with the design and whether the facility is ready for installation works.
Typical lift installation defects include misaligned guide rails, incorrect door clearances, insufficient equipment fixation, discrepancies between the installed components and the approved design, and errors in connecting safety devices.
After the equipment has been installed, lift adjustment is carried out. Specialists adjust the drive, brakes, doors, sensors, cabin stopping accuracy, and control system.
The lift is then tested in the operating modes specified for the equipment. Safety device testing includes the safety gear, overspeed governor, shaft door locks, and other components that affect safe operation.
The General Technical Regulation on Lift Safety requires separate verification of safety components, while compliance testing with the requirements of the regulation is carried out by an accredited testing laboratory.
Testing a lift after installation should not be limited to several trips with an empty cabin. The equipment must be checked under the required load, including stopping accuracy, braking, door operation, communication systems, emergency modes, and operation of protective devices.
An initial technical inspection of the lift is carried out before newly installed equipment is put into operation.
Before this, the installation contractor and general contractor inspect and test the lift. If the results are satisfactory, a technical readiness certificate is issued.
Based on the results of the technical inspection, the commission prepares a lift acceptance certificate. In practice, this may also be referred to as a lift commissioning certificate.
In cases provided for by the applicable regulation, test results obtained during certification may, subject to approval by the authorised body, be accepted as the initial technical inspection.
After the lift has been put into operation, technical inspections must be carried out by a specialised organisation at least once every 12 months, with the results recorded in the equipment passport.
Documents required for lift acceptance must confirm the origin of the equipment, quality of installation, test results, and readiness for safe operation.
The documentation package usually includes the lift passport, certificates, design and manufacturer’s documentation, technical readiness certificate, lift test reports, completed work certificates, and documents confirming inspection of safety devices.
Installation and commissioning works must also be reflected in the as-built documentation. The documents must correspond to the equipment actually installed rather than only to the original specification.
A lift may only be put into operation after all required inspections, technical examinations, and mandatory documentation have been completed.
Who accepts the lift for operation and who is included in the acceptance commission is determined by the applicable technical regulation and the characteristics of the equipment.
Acceptance of the lift after installation confirms that it complies with safety requirements and may be used for its intended purpose.
However, signing the documents does not eliminate the need to verify the actual quality of the installation.
It is particularly important to compare the equipment passport, certificates, test reports, and acceptance documents with the components actually installed.
Lift installation is a sequential process in which the quality of every stage affects the safety and service life of the equipment.
Proper lift installation begins with preparation of the shaft, continues with precise installation of the equipment, and ends with adjustment, testing, technical inspection, and acceptance.
Independent supervision helps identify defects before the equipment is put into operation, assess the quality of the installation contractor’s work, and ensure that the documentation corresponds to the works actually completed.
