The installation of home office elevators in the factory premises is necessary and ensures the safety of users. The elevator installation must comply with safety standards before it is accepted and put into operation.
The installation of home office elevators in the factory premises is necessary and ensures the safety of users. The elevator installation must comply with safety standards before it is accepted and put into operation.
Before the elevator is installed, the technical staff to install the stairs of the supplier and the investor need to know the work and the process of installing the entire elevator. This article will help users visualize the work when installing elevators.
Safety preparations when installing elevators
- Elevator pit doors must be carefully covered during construction
- Elevator wells must be arranged with enough light
- Installation operations must be performed in accordance with technical standards such as electric welding, pulling heavy objects must not cause danger to elevator users.
- Prepare safety helmets during installation
- Safety cables must be dropped along the pit and used
- Absolutely follow the safety rules
- Check and supervise the good implementation of requirements on occupational safety
Standard elevator installation process
Step 1: Receive and check the quality of elevator components and materials. Prepare the necessary equipment and tools.
The quality of elevator components plays an important role, it directly affects the stable, smooth, durable and safe operation of the elevator.
Before the witness of the investor, the contractor, the materials staff handed over all the components for the elevator installation.
In charge of the project receiving tools and equipment:
+ Survey to prepare the power source for construction to meet the standards
The location of the power source ensures convenience during installation
+ Power source capacity meets construction standards
+ Prepare electrical connection equipment for welding machines and other tools
+ Equipment for lighting pits
+ Close the installation operation rig
+ Close the construction rig
+ Drag the equipment to the engine room
Step 2: Construction warning system on floors where vertical lifts are installed with fixed truss frame
Release the seat belt to transport the control cabinet motor to the engine room
To ensure the safety of users, it is necessary to have danger signs and install barriers at the construction site
Ensure accuracy during the installation of the elevator that needs to be calibrated and measured accurately.
Use Plan to transport the motor, cable control cabinet to the engine room.
Step 3: Install the working platform
The working floor is the place where elevator engineers will directly manipulate and install the elevator. Installation of the working floor must ensure the electrical safety and structural safety of the floor.
Install the top standard floor: the top standard floor will be installed on the top floor (below the engine room floor).
Install the lower standard floor: The lower standard floor will be installed in the pit.
Step 4: Install the overspeed controller and install the tractor, control cabinet.
Install a safety brake system under the elevator cabin frame and the overspeed elevator controller, test the stable and safe operation of the system.
Special attention is paid to safety devices when installing elevators, ensuring safety in the process of using the elevator's speed controller so that the elevator's speed will operate within a safe limit. .
If the elevator runs above the allowed speed, this part will work to bring the elevator back to the allowable safe speed.
Determine the location to install the tractor, the control cabinet based on the construction design drawing of the elevator.
Installation of the machine room includes the installation of the tractor, the installation of the electrical cabinet, the corrugated iron of the machine room.
Using a hoist to put the motor, control cabinet, load cable, cover sheet to the machine room, install it according to the design drawings. Install and set parameters for control cabinets.
Step 5: Install the rails
Focus on immediately transporting the guide to the Thang well area
Use the cabin floor frame that has been installed with a safety brake system to install the remaining guide lines.
Guide rails will be installed one by one with the method of using electric hoist to pull the guide wires into the correct position.
The guide rail ensures that the cabin and counterweight are always lying and moving in the correct position designed in the well. This job requires absolute precision so that the elevator can operate stably and smoothly, most durable, safest. Install the first two guide wires for the Car and CWT, using the scaffold to position the bracket.
Step 6: Install counterweight
The counterweight has a role to help the cabin operate stably in both up and down directions in 2 modes with load and no load, the counterweight moves co-planar with the cabin but in the opposite direction.
Installing counterweights is a key step in the elevator installation process
Installing counterweights is a key step in the elevator installation process
Step 7: Install the elevator cabin
The process of installing the elevator cabin is done inside the elevator well.
Install the cabin floor frame (with safety brake).

Step 8: Release the steel cable and adjust the cable
Cable traction system of elevator cabin
The counterweight frame is located on the bottom floor, the cabin frame is on the top floor and will be fixed by the Pole until the load cable installation and adjustment is completed.
Step 9: Install the floor door
Installation of elevator landing doors is done at the final stage
All floor door equipment will be delivered in front of each floor door
After installing the load cable, we use the cabin floor to install the landing door.
Install each door and in sequence from the top down to the lowest floor door.
Step 10: Install the wiring
Install the power cord for the tractor assembly
Install the control wire on the machine room
Using the cabin frame, install the control wire in the well in the order from top to bottom
Install signal devices at the landing door
Installing dynamic cables in wells
Step 11: Install the cabin wall, cabin door and control panel in the cabin
The cabin floor is located on the lowest floor
Clean the elevator
Install cabin wall, cabin roof
Installation of cabin doors and door operating systems
Mount the control panel in the cabin
Wiring system connection
Step 12: Check, adjust
Check and calibrate the operation specifications of the elevator
Before the test run of the elevator, it is necessary to conduct the final measurement and inspection with measuring devices to eliminate all possible abnormalities even the smallest.
Use the most modern equipment to test and measure technical parameters.
Adjust the technical parameters of the ladder to ensure the most stable, smooth, safe and durable operation of the ladder.
It is strictly forbidden for people who are not supposed to test the elevator during operation.
Step 13: Check the elevator inspection
The process of elevator inspection and maintenance is extremely necessary, this appraisal will be conducted by the state inspector of occupational safety of the Ministry of Labor, War Invalids and Social Affairs.
Quality inspection is an indispensable step in the elevator installation process
Quality inspection is an indispensable step in the elevator installation process
Step 14: Acceptance and handover to customers to put the ladder into operation
Before handing over the elevator to the investor and putting it into actual use, the elevator must be inspected by a state agency and granted a license to use the elevator.
Step 15: Handing over the elevator
Perform final cleaning, test run, and align specifications if necessary. Prepare completion documents, handover elevators to customers.
