2D laser scanners, be sure not to slam!

Automation and safety in warehouses are managed by various tools. For years, Tamarri has put safety at the center of its business, thanks to the safety first paradigm! Today we want to introduce you to a truly cutting-edge product: 2D LiDAR sensors (also 2D laser scanners) suitable for surface measurement and detection functions.

How the 2D laser scanner works

Based on the principle of light propagation time measurement, compact devices scan the surrounding environment and measure distances. Thanks to the integrated rotating mirror, a two-dimensional monitoring of protected areas is generated, which are individually definable.

The new sensor-based, rear collision avoidance system of the latest generation is enclosed in a very strong 5mm-thick metal stand easy to install even on the ballast of the truck.

Our SS61K kit consists of:

– 2D LiDAR sensor with mounting bracket

– 12-24vDC relay box

– Led lamp with buzzer

– Connection cables

Regardless of the angle at which they are placed, SICK’s 2D LiDAR sensors always work reliably and accurately, both indoors and outdoors. For navigation, surveying or measurement, 2D LiDAR sensors provide reliable measurement data in numerous applications: from warehouses to manufacturing and from port areas to construction sites.

 

Two different intercept areas can be set, each managed by a separate digital output, adjustable in scan amplitude from 0 to 120°, in obstacle detection distance from 20/800cm.

The sensor performs a two-dimensional “2D” scan and detects both people and stationery or moving obstacles with an accuracy of 5 cm, with an almost immmediate responsiveness to the obstacle on the outputs.  However, it is necessary to define the mounting position of the sensor on the vehicle, with special attention to ‘height, depending on the use needed by the customer.

Warehouse operation

The most common application of the sensor is on the rear ballast of the truck at about 40 cm height, so that the sensor is able to intercept even obstacles on the ground.

Settings of two different detection areas:

– Area 1, with 120° scan depth 6..7m first slowdown (orange area);

– Area 2, again scanning at 120° depth 2..3m second slowdown (green area).

The two digital outputs coming from the sensor are sent to the relay board ( 3 relays CO.NC.NA ) to which the supplied led lamp is connected, which transmits the danger status to the operator in the form of color and acoustic signal; in addition, it is possible to configure the slowing down of the vehicle.

– No obstacle, green light and no acoustic signal

– Obstacle in area 1, orange light with intermittent acoustic signal

– Obstacle in area 2, orange light with continuous acoustic signal

 

In some applications, the lamp is used as the only hazard warning, without intervening in the slowing down of the vehicle, making it easier and faster to apply the kit.

SICK safety laser scanners combine know-how and experience with excellent performance.

Tamars, automation and safety! 😉

Brakes maintenance

Brake maintenance. Brakes  and all related components represent one of the most importantl systems for the safety of any vehicle. What is their function and how to comply with adequate maintenance?

Brake maintenance. How do the brakes work and how is adequate maintenance complied with?

Brakes and attachments are fundamental components for moving vehicles. Their main aim is to convert the physical pressure exerted by the user on the brake pedal.

One of the fundamental components of the brake “system” is the master cylinder. It is easy to understand how much the quality of the brake pump is of primary importance to guarantee the best performance of the vehicle. The material with which a brake master cylinder is produced must be resistant to wear,  must be safe and must guarantee very high standard levels.

In this regard, the use of cast iron and steel ensure the seal of the component over time. Aluminium could also be used, which make brake pumps lighter, but still resistant and able to guarantee the same performance.

Brake maintenance. How is security maintained

Tamarri S.r.l has always been involved in forklift safety. More and more frequently there are reports of accidents at work due to poor and “distracted” maintenance. Too often we are informed of accidents because maintenance has not been expected  by competent and specialized personnel.

Regarding this, it is essential to do a regular and accurate monitoring the operation of the vehicle. A detailed analysis follows and the subsequent replacement of the worn part with the new one. To ensure that the analysis is always timely, many companies have already specialized in predictive analysis of the medium.

In the field of safety, why are the brake pumps of a forklift truck a fundamental element?

The brake pumps are very important, not only for the performance of the vehicle, but above all to safely manage the various activities.

Anyone who has had anything to do with forklifts will have noticed that. As time passes, there is less and less precise braking of the forklift. This is due to the loss of tightness of the internal rubber pads.

But why do the rubbers tend to decrease their hold? In several years, it is normal for the rubber pads to undergo normal wear. Furthermore, their duration is closely linked to the operator’s driving style.

For example, the habit of abruptly braking or the tendency to keep the foot lightly resting on the brake pedal, are all attitudes that represent a threat to the life of the rubber pads. If the grommets are worn out by some bad practice, the pump itself will also suffer the consequences.

Brake maintenance. What are the alarm bells for noticing brake wear?

It is not difficult to notice that the brakes are starting to wear out. Just keep an eye and monitor the vehicle often in order to check it. The punctuality of the forklift braking takes place in a decidedly less efficient way.

When the problem gets worse, you will notice that the brake pedal goes down empty. At this point the situation is worrying and the forklift is no longer safe: all that can be done is to stop it and ask for help from technical assistance.

How can the problem be solved?

It is essential not to underestimate the signs of malfunction and to know how to promptly remedy this malfunction. To prevent an inconvenience from turning into a serious risk for the operator and pedestrians, it is essential to resort to a specialized technician.

If the technician deems it necessary to replace the brake master cylinder, he will intervene directly at the customer’s site. In fact, the sealing rubbers are not easily replaceable by anyone because they are located within the single central block. Therefore it is an operation that requires about 2 or 3 hours of specialized work of a competent technician.

Forklift maintenance: a commitment to safety

Monitoring the operation of the forklift means making a daily commitment to ensure safety at work.

If you are looking for spare parts for the entire braking system, made to ensure resistance over time, excellent quality and delivered in a very short time (24/48 hours), Tamarri S.r.l is the company for you!

Industrial IoT: five objectives to achieve within 2021 by elaborating datas in a comptetent way

Industrial IoT: Let’s clarify the data reading

Often due to the difficult interpretation, some entrepreneurs do not fully exploit what can be obtained from data and the value they can generate. A value often not clearly identifiable. Let’s try to clarify.

We assume that data is increasingly a strategic asset for any business. So it is clear that knowing how to decode them, understand them is important to be able to activate an entrepreneurial policy that takes into account their forecasts, which will make the difference.

Let’s analyze five aspects that are able to make the company competitive. These are extremely concrete aspects that can be achieved during the year. How? With a correct and competent analysis of the data generated by machinery through Industrial IoT solutions.

Five objectives for a competitive company

1. Ordinary maintenance

OEMs, i.e. Original Equipment Manufacturers (original equipment manufacturers) play a key role right now. To concretely assist their customers by encouraging rigorous and constant maintenance.

How? They Decline their know-how to the analysis of diagnostic data collected over time. This activity, which should become a real program, will produce value over time that will lead to an increasingly predictive, precise and effective analysis.

2. Know your customers

The analysis of data from IoT is a fundamental tool in order to learn about the machine life. Through the data it is possible to understand if the operators are using them correctly and how and when maintenance is done

This is how you can understand if there is room to use them even better to achieve maximum efficiency and therefore full customer satisfaction.

3.  Predictive problem analysis

Accessing the data allows greater proactivity towards the customer because it allows you to act before the assistance channels are activated.

How? By equipping the after-sales service with the tool able to monitor the connected machines. By doing so, it is possible to identify in time critical and alarming situations, unsafe working conditions or major failures

4. To Understand concretely how to improve the machines

Thanks to the correct use of analytical data it becomes less complex to understand how to improve the product in terms of mechanics and engineering. The technical and R&D department itself can also benefit from this.

5. Be more proactive towards the final customer

For every company is foundamental the need of manufacturers, which is to capitalize on product know-how effectively, thus improving knowledge of the machinery.

Only by doing so it will be possible to be closer to customers, with the common aim to increase and finalize the productivity and competitiveness levels.

To achieve this virtuous circle, an effective paradigm is to offer training on maintenance and process optimization, offering the possibility of remote diagnostic assistance and new methods of guarantees.

Tamarri S.r.l. is able to provide a complete solution in this area: discover our SMARTPASS 4.0 EVO platform for the complete management of the vehicle in  cloud.
