Why confirm the quantity of turnstiles?

With the development of society and the increasing demand for security, more and more places need to install all kinds of turnstile gates. Before that, you need to calculate how many turnstiles do I need? This is a very important problem for your project or turnstile security solutions.

According to my experience in chatting with many clients, Many people still encounter a problem when choosing the turnstile gate, they don’t know how to judge how many turnstile gates do they need. How many turnstiles do I need?

Some turnstile manufacturers often hope that the more security turnstiles customers can choose, the better in order to create more sales performance. Therefore, if you can’t make the right choice or the most appropriate choice about how many turnstiles do I need, Sometimes, they not only spend more money but also take up a lot of space.

In fact, if consumers can make their own right judgments, if they can choose the correct types of turnstiles (tripod turnstile, swing turnstile, flap barrier turnstile, sliding turnstile, speed gate turnstile, full height turnstile)and the correct quantity of turnstiles, they can avoid spending more money and achieve the expected purpose of installing the security turnstile gate. If you don’t know what kind of turnstile do you need, please check our another article: How to choose a turnstile?

How many turnstiles do I need?

Generally speaking, this is a very simple and easy thing, and there is no need for specific or complex formulas to calculate. This will make many customers more confused. After complex calculation formulas, they still don’t know how many turnstiles do I need.

In general, for full height turnstiles and tripod turnstiles, if the required style type is determined, we only need to determine the number of turnstiles required based on the size of the installation site. Below, we mainly focus on flap barrier turnstile, swing turnstile, and speed gate turnstile, which may require installation of multiple channels on site to provide a simple explanation of how many turnstiles do I need.

Do you know how to determine the installation quantity of the turnstile gate? Let’s illustrate based on a specific case. The turnstile machine is divided into single-core and dual-core, which means it can be combined arbitrarily. Firstly, you can determine the installation quantity of the turnstile machine based on a specific installation size on site. Secondly, you can determine the required quantity for installation based on a specific requirement.

For example, if a customer’s installation site requires two directions of entry and exit, there are three solutions with different quantities of turnstiles. The first solution is to install a combination channel of three turnstile gates, two single-core and one dual-core. The second solution is to install a channel of two single-core types if the on-site size is not enough. Of course, if the pedestrian flow is high, This selection method may result in congestion of personnel entering and exiting. The third solution is to install two channels of two single-core types, which need four turnstiles. This way, it is more suitable for entering and exiting from different locations.

Two single-core turnstiles form a passage channel, while one double-core turnstile and two single-core turnstiles form two passage channels. Two dual-core and two single-core turnstiles form three passage channels, and so on; If an installation site is designed in this way, it can save budget costs. However, if it is installed at two entrances and exits in the same office location and requires two channels, four single-core turnstiles will have to be used, and a combination of two single-core turnstile channels will be used.

What factors determine the quantity of turnstiles

The installation quantity of turnstiles is crucial for ensuring orderly access control management and the safety of the premises. The following factors will affect the installation quantity of turnstiles we need.

1. Channel width:

This is the decisive factor in determining the installation quantities of turnstiles, directly determining the type of turnstile used and the number of products installed. The channel must ensure that there is sufficient space to install a certain number of turnstiles and ensure their good operation.

2. Traffic:

The traffic at the installation site also determines how many turnstiles do i need to install. If there is a high pedestrian flow in a place, it is necessary to install a sufficient number of turnstiles to ensure the orderly passage of personnel and the safety of the place. So we need to understand the average pedestrian flow at the installation site, what is the peak pedestrian flow, and the potential increase in pedestrian flow in the future, and then make corresponding adjustments to the number of turnstiles.

3. Type of product:

The type of turnstile directly affects the required number of turnstiles. Because different types of turnstiles have different sizes. We need to determine the type of turnstile to be installed based on the actual installation site, in order to determine the number of turnstiles to be installed.

4. Security level:

The security level required for the installation site also directly affects the number of turnstiles required. The types and quantities of turnstiles required for places with high safety levels need to be adjusted accordingly to ensure the safety of the place.

5. Engineering budget:

The customer’s project budget also directly determines the number of turnstiles that can be installed. If the customer’s budget is high, they can install a larger number of turnstiles and turnstile types with higher safety levels. If the budget is low, they can only install a smaller number of turnstiles with lower safety levels.

Therefore, we must provide each customer with detailed instructions for use and installation. Every customer who cooperates with us never needs to worry about any problems. Mairsturnstile provides professional technical support and after-sales service to every customer.

Next, Mairs will make a brief introduction about how many turnstiles do I need, in this way, most customers can clearly know how many turnstiles do I need for the access control projects or turnstile security solutions? There are two aspects to consider how many turnstiles do I need?

Judge the quantity by the flow of people:

Judge and confirm the quantity of turnstiles according to the flow of people.

To judge the quantity of turnstile gates, we should first confirm according to the actual number of people. For places with a relatively fixed number of people, such as office buildings and large factories, it is simple and easy to confirm the number of passages. For example, if the total number of people in a factory is 1000, We should consider not only how long it took for all personnel to pass, but also how long it would take to evacuate the crowd in case of an emergency to measure the number of passages.

If 1000 people need to escape in case of an emergency, 60 people can pass through the emergency passage every minute, so it takes at least 4 passages to evacuate 1000 people within 5 minutes.

Therefore, According to the actual number and situation, the turnstile gate manufacturer will probably recommend that the factory install 4-5 passages, so that congestion will not occur in a short time during normal commuting hours, because most ordinary employees who work normally will clock in in a fixed period of time. If the number of passages is too small, they are likely to be late, Therefore, when considering the number of passages, we have to consider many factors. We need to take all kinds of uncertain factors into account so that we can finally make the right choice.

Because of this, we can’t calculate how many turnstiles do I need through a simple formula. We must make a decision in combination with the actual situation. The number of passages determines the quantity of turnstiles, so we have the basis for judgment.

In some special cases, the estimate of the number of people will not be very accurate. For example, in scenic spots, subway stations, and other places, the number of people may increase sharply on weekends or holidays, but usually, the number of people is not too many. Maybe 2-3 channels are OK. However, we should consider the situation of a large number of people on holidays, because any scenic spots receive tens of thousands of people on holidays. 

If there are only 2-3 passages, we may not be able to enter the scenic area in a row for a day during holidays. In case of an emergency, we can’t evacuate the crowd, which is a very dangerous thing. We install pedestrian turnstile gates for safer and better protection, rather than becoming our shackles in case of danger. Therefore, professional turnstile gate manufacturers will suggest that more than 8 passages should be selected for the entrance of scenic spots and subways, especially in densely populated areas. 2-3 passages can be opened in normal time, and all passages can be opened in holidays to avoid congestion and affect the travel experience.

Through the examples of scenic spots turnstile and subway turnstile above, it is easier for us to understand that the quantity of turnstile must be determined according to the actual environment and actual demand, rather than just calculated by a simple formula, the number of passages determines the quantity of turnstiles, so we can easily get the answer of how many turnstiles do I need.

Judge the quantity by the passage width:

Judge and confirm the quantity of turnstiles according to the passage width. Each type of turnstile needs a different space. Let’s introduce them respectively.

Tripod turnstile gate:

composed of three rods, the standard length of the rod is 51cm, and the length of the bars can only accommodate one person. It is suitable for one-way or two-way control of pedestrian flow, and the traffic speed is ordinary. The body of the standard bridge-type tripod turnstile gate is 28cm. Therefore, the road width required for a passage is 83cm.

The tripod turnstile is widely used in the simple dissuasion level access control of the public channels. It is commonly used in the attendance system of enterprise, office building, the consumption system of supermarket, shopping arcade, the security access control system of smart residential, the ticket checking management of subway station, train station, scenic spots and other venues, and the palm-shaped system management of construction sites.

With all kinds of different configurations, it can be applied to all construction sites or other environments and can solve all the control issues of security access control management. The turnstile gate adopts the arms drop mode. If there is an emergency, cut off the power, the horizontal arm will fall down, then it can form a barrier-free pedestrian passage, which is convenient for personnel evacuation in an emergency and provides a guarantee for traffic safety.

Flap barrier gate:

It is suitable for one-way or two-way control of pedestrian flow, and the traffic speed is fast. It is commonly used for personnel access control management; it has the advantages of a fast opening, safety, and convenience, and is a perfect management and dredging equipment for a large flow of pedestrian access; it has been widely used in airports, subway stations, train stations, wharves, scenic spots, parks, unit pedestrian passages, etc., which can cooperate with smart cards to realize off-model ticketing management system function and form unattended management of personnel access.

it is composed of at least two lanes. The width of the passage is generally less than 55cm( some are 60cm). The standard casing width is 28cm( some are 30cm). So for one lane, it will need 111cm space. If there is more than one lane, the middle one will be double core. For two lanes, it will need at least 194cm. The flap barrier turnstile gates need more space than the tripod turnstile.

There are also double retractable turnstile gate, handicap turnstile, which is used for the handicapped. The lane width is 900mm. The casing is 35cm.

Swing turnstile gate:

The swing turnstile gate has the largest passage width among all pedestrian turnstile gates. The length of the swing arm can be customized. The standard length of single-lane width is 60cm, and the maximum length is 900cm. The casing width of the swing turnstile gates is various. For the common swing turnstile gate, it is 28cm as standard. For a slim swing turnstile gate, it is 18cm. The fast lane speed gate is 12cm. The standard lane width is 60cm. It can be customized to 150cm if comes with a servo motor.

It is suitable for one-way or two-way control of pedestrian flow and vehicle flow (electric vehicle and tricycle). The speed in general. It is mainly used for the management of passageway entrance and exit, Generally, only people are allowed to pass through the application site or people with luggage, and people with disabilities can pass through. Considering that the swing turnstile gate can achieve wider passage characteristics than the flap barrier gate. Most of the swing turnstile gates can be mixed with pedestrians, bicycles, mopeds, disabled vehicles, and other non-motorized vehicles.

Sliding turnstile gate:

A sliding turnstile gate, also known as a full-height flap barrier gate, is an upgrade product of an ordinary flap barrier gate. It is called a sliding gate turnstile, full-height sliding turnstile, prison flap barrier gate, etc. There is no special term in the industry, and the general name is full height sliding turnstile gate. A full-height sliding turnstile gate is a special mechanical device for personnel access control. The standard lane width is 60cm. Now there are options for 90cm. The casing width is normally 35cm. It is like the flap barrier turnstile. There should be at least 2gates to be one lane. So the road width required will be 130cm. If two lanes, at least 225cm needed.

Full height turnstile gate:

In the rotary operation, the passage width is generally 65cm, suitable for one-way or two-way control of pedestrian flow, and the traffic speed is slow. Turnstiles are mainly used in prisons, military administrative areas, and factories with strict access control (such as chemical plants, construction sites, etc.). The inside turnstile mechanism of the security turnstile contains an emergency control device. When the power is off, the central rotating arm can rotate freely to ensure the passage is unobstructed; when it is powered on, it is automatically locked. The width of a standard single-channel full height gate is 163cm and that of a double channel is 230cm. The size can be customized based on requirements.

In short, if the road is not wide enough, you can choose a single tripod turnstile gate, which can save space and cost. If there are requirements for the passage of the disabled or luggage, you can choose the swing turnstile gate. There are various styles of swing turnstile gates. The width of the passage can also be customized. Different choices can be made on different occasions. The width of the swing turnstile gate can be increased by 900mm, which can meet the needs of a wheelchair or luggage. The double flap barrier turnstile can also be considered, which will cost more than the ordinary flap barrier.

The passage speed of the flap barrier gate is relatively fast, and the space required is relatively large. The space required by the sliding turnstile gate is larger than that of the flap barrier gate, and the passage can also be wider than that of the flap barrier turnstile. The full height turnstile gate occupies the most space in all access control turnstile gates, and its safety performance is also the highest. The most suitable turnstile gate can be selected according to different road widths and different places.

The quantity of turnstiles to install should refer to the emergency situation and our actual needs at ordinary times. We should not blindly confirm the number and necessity of passages, or even do not know how many passages to select. Of course, we also need to refer to the reasonable suggestions given by the turnstile gate manufacturer, so as to achieve a better use effect of turnstile gate.
