What civil works are necessary before installing my elevator?

Check the status of the civil works of your project to be able to install your equipment

JUAN DAVID VERGARA MACANA
Perhaps you have asked yourself the question: What work is necessary to start with the installation of my elevator? Well, we tell you that in order to guarantee a good process and be efficient, you must make adjustments to civil works and electrical works before the elevator contracting company arrives at the building. At GOLD elevators we divide our execution into three phases: the first refers to the civil works adaptations necessary to install the frames, guides and headboards, the second contemplates the electrical works, to place the cabin, the machine and the control; and the last one focuses on the adjustment and completion of the elevator.

Verification of your work

To guarantee safety and efficiency when starting the installation of your elevator, you should check the space where the elevator will be installed. The installation of the elevator consists of 3 phases and for these some requirements are needed according to the progress of the work:

  • 1 phase: installation of door frames (hall) and guides (counterweight and cabin).

  • 2nd phase: installation of the cabin, hoisting of the machine and other electrical and mechanical components of the elevator.

  • 3 Phase: load tests and final adjustments that will give your elevator smoothness and comfort.

First phase

Elevator shaft:

  • Well plastered and painted white: It is important that when doing this work, the measurements provided in the plans of the well are respected. The plaster applies when the well is in masonry.

  • Clean well: Well cleaning, according to NTC 2769-1 Chap. 5, in order to prevent civil works debris from coming into contact with the mechanical and electronic parts of the elevator, causing damage to the equipment.

  • Well with light: Installation of a light system with a minimum intensity of 50 lux according to the NTC 2769-1 Chap. 5, which must go: embedded in the wall, so that it does not obstruct the route or the elevator devices; the lamps (tortoise type) must be located on each floor, additionally on the upper level or machine room and on the lower level (-1.30m); It must have switchable ignition at the beginning and end of the well.

  • Waterproof well: Waterproofing according to NTC 2769-1 Chap. 5, in order to prevent the mechanical and electronic elements from being melted by contact with water by seepage.

  • Safe access: According to the NTC 2769 standard, there must be a suitable place for access to the machine room, for this reason we recommend that the ladder meet the following characteristics: Have a height of less than 4m and a distance of between the wall and the steps greater than 15cm; the width of the ladder greater than 25cm; Provided with a safety mechanism for anchoring people, if the ladder is more than 1.5m, arch protectors must be placed on the back of each step.

  • Door with lock: According to the NTC 2769 standard, it is necessary to install 2 doors: a door for access to perform maintenance on the machine and a trap door to carry out rescue operations. the doors must have a lock and padlock that guarantees the exclusive access of the elevator personnel to the machine room and to the overrun of the shaft in order to avoid accidents due to ignorance.

  • Machine room paneled and painted white. It is important that when doing this work, the measurements provided in the well plans are respected.

  • Machine room with light: Installation of a lamp (tortoise type) with a minimum intensity of 200 lux according to the NTC 2769-1 Chap. 5

  • Machine room plate: Casting of the machine room plate according to measurements provided by a representative of Ascensores Gold System Ltda.


Electrical installation:

  • Three-phase current: Installation of suitable outlets for three-phase and two-phase current (provisional panel) near the pit, 5 meters.


Storage

  • Deposit to store material: Adaptation of a clean, safe, exclusive place on site and with an area proportional to the size of the elevator, where all the installation material will be stored. If we do not have an exclusive space for Ascensores Gold, we cannot guarantee the finishes of the elevator, since the elements would be exposed to the contingencies of a work and will be the responsibility of the builder.

  • Deposit to store installers' tools: Adaptation of a place (waterproofed, clean and safe) for storage of installers' tools and utensils, this item applies in the event that the aforementioned deposit is far from the place where the elevator will be installed.


Second stage

Elevator shaft:
