Hello. Legal analysis: three situations can not be installed elevators:

1) Buildings that have been identified as C and D by the housing safety appraisal agency cannot be installed; (2) Buildings without pile foundations, structural columns, ring beams, and floor slabs with perforated slabs (floor slabs are perforated slabs, but pile foundations, columns and ring beams can be included) cannot be installed; (3) The elevator is to be installed in the location of the building, which has been buried with septic tanks and other pipelines (chain nets) that cannot be moved, only the oak can not be installed; (4) Buildings without legal ownership certificates cannot be installed; (5) Buildings on collective land cannot be retrofitted;

Legal infiltration of the shed basis: The "Guiding Opinions on Comprehensively Promoting the Renovation of Old Urban Communities" stipulates that the project of adding and installing elevators in old communities supports residents to withdraw housing provident funds.

Since the elevator installation is a kind of high-altitude operation, in order to facilitate the installation personnel to carry out construction operations in the hoistway, the general contractor should cooperate with the needs of the elevator installation, build scaffolding in the appropriate part, the hoistway should be dedicated to the elevator, and the hoistway shall not be installed with equipment and cables unrelated to the elevator.

There should be good anti-seepage and anti-leakage protection in the pit, there shall be no water accumulation in the pit, and each floor should have a horizontal datum mark, and the safety protection of the elevator mouth should be done before the elevator is installed.

According to the location of the machine room, the elevator of the machine room at the top of the hoistway (upper machine room), the elevator of the machine room next to the bottom of the hoistway, and the elevator of the machine room inside the hoistway (without machine room).

Elevator classification.

Button control elevator: It is a simple automatic control elevator, with automatic leveling function, and there are two common control modes: button control outside the car and button control inside the car.

Parallel control elevator: the control lines of 2 3 elevators are connected in parallel for logic control, and the summoning button outside the landing station is shared, and the elevator itself has the function of selecting the front cluster.

Before the elevator is installed, the construction unit shall submit a notice of commencement to the local Bureau of Quality and Technical Supervision.

Then go to the testing department for installation supervision and inspection and submit the corresponding qualification certificates (such as: the slow branch production license of the ladder, the type test certificate of the whole disturbance and the components, the installation, transformation and maintenance license, the construction personnel certificate, the order and installation contract, the speed limiter and the safety gear debugging copy, etc.).

Pay a fee. The user unit provides the elevator management personnel certificate, the elevator use rules and regulations, and the elevator maintenance contract.

After the elevator is installed, the construction unit shall calibrate and debug the elevator in accordance with the requirements of the safety technical specifications, and issue a self-inspection report after the end. The elevator draft inspection department (special inspection institute or research institute under the Technical Supervision Bureau) conducts acceptance inspection of the elevator on the basis of the self-inspection of the construction unit.

It can be put into use only after passing the test.
