How Do I Choose A Passenger Lift?

 Elevator installation is a well-established business, however, with office space and energy prices on the rise, change is underway. Most buildings over four stories use traction lifts. A motor at the top of the shaft turns a pulley - basically a sheave - which raises and lowers a cable attached to the car and counterweight. In slower systems, gears connect the motor to the pulleys. Faster lifts are gearless; the pulleys are directly connected.

Either way, these machines usually fill the entire room above or next to the shaft, occupying what may be the main space on the top floor. However, innovation allowed builders to squeeze the equipment at the head of the shaft itself or against a side wall.

At the same time, the manufacturer is using gravity to save energy. The counterweight chosen is comparable to 40 to 45 percent of the car weight at full capacity, which reduces the required motor output. However, when an empty lift has to rise, the fall of the heavier counterweight provides too much energy; the huge resistance dissipates the excess energy as heat. The same resistance is required when a fully loaded car (heavier than the counterweight) descends. However, the new regenerative drive converts the wasted energy into electricity.

Customized Passenger Elevator with High Quality

Improved scheduling technology is improving human efficiency in buildings with multiple shafts. Office buildings are cramming more people into existing floors, but the increase in population slows down lift service. To compensate for this, installers are replacing the 'up' and 'down' buttons in the foyer with numbered displays or touchpads. People who want to take the lift press the number of the floor they want and the computer tells them which lift they should take, grouping people who are going to the same or adjacent floors. The computer schedules the lifts so that each one goes to a small number of nearby floors, rather than travelling randomly above and below. This solution reduces waiting times and energy consumption.

Key factors in choosing a passenger lift

The type of passenger lift required for a busy shopping center is very different from that required to handle vertical traffic in a residential tower. Even though the dimensions and load capacity are identical, the particular combination of features, machinery, and equipment depends on the specific requirements of each project and leads to very different solutions.

 

 Passenger Elevator for Residential Building

Any professional who takes on a project involving the installation of one or more passenger lifts must first analyze the various factors that are key to achieving success.

What type of building are we dealing with? A flat that needs a fast, quiet and efficient lift system? A public building that needs more robust lifts to cope with increased passenger traffic and the wear and tear that comes with it? A factory that needs to be equipped with passenger lifts for goods?

How many lifts are needed to cope with the traffic flow in a given building?

What lift speeds and load capacities are required to effectively handle the vertical traffic in that building?

What specific technologies are best suited to the requirements of a particular project?

Using the knowledge and experience of the companies that actually design and build lift systems is the best way to ensure that good and accurate advice is obtained on the design of the lifts that will eventually be manufactured and installed on the job. Our engineering department's project studies include a detailed assessment of the following factors.

The specific requirements of the project

The number of stops

The distance between floors

Estimated passenger traffic

The required lift car capacity

Number of residents

Estimated lift waiting and travel times.

The final selection of the most suitable passenger lift system for the building resulted in the identification of the specific type of lift required for the building and the number of lifts required to effectively transport the total number of building occupants, whilst minimizing passenger waiting times and ensuring that the system was equipped with all the necessary features to best address the specific vertical transportation requirements of the building in question.

At BDFUJI Elevator, we take great care to ensure that our clients and their consultants stay within budget, complete their work on schedule and maintain the highest possible quality standards. It, therefore, makes sense for us to be closely involved in the planning stage of a lift in order to provide the most suitable solution for the completed project.
