What is the big problem of big booms?

If you have a large-scale project, a concrete pump with big boom would be the best choice. The fact is undeniable that cutting-edge big boom pumps are highly speedy, effective and economical for high rise and horizontal conveying concrete. Therefore these pumps are frequently asked for every kind of big-sized construction projects.

In order to meet this growing demand concrete pump manufacturers have been racing for a bigger boom. Every year or at the construction fairs we hear that a company slightly surpasses its competitor in boom height. It seems that this race is not only for the function of the machine, but also just to say I am the greatest in this field!

Following questions are frequently asked:
-Where does this boom height race end?
-Are these high booms realistic or exemplary for competition?
-We heard about 101 meter, when we expect 102 meter?
-Still standing without any support over 100 meter, as if impossible!
-What is the largest boom size put into practice for daily work at a project?
-Using big boom pumps is a boon or a bane?

In fact, boom manufacturing was a separate specialization from pump producing. In the past, boom work is a different area of ​​expertise with its steel structure and welding technology.
And there were some concrete pump producers in competition
using the same booms from the same manufacturer.

When we come to today, the following questions come to mind;
-How much time and how much area are needed to install big boom pump?
-Big boom means big outriggers?
-How do you prime the big boom and get it back?
-What are the practical problems with these booms in terms of control?
-Is there any difficulties to clean the big booms?
-Whether the double-layer wear-resistant conveying pipe is suitable for big booms?
-Are these big booms for special missions and projects only?

On the other hand, should we need to classify the operators as big (over 60m for projects) and standard (less than 60m for readymix) boom pump operators? Because using huge booms is not an ordinary job and placing concrete at such height is very tough tasks.

A new generation of huge boom pump operators with keen eyes will be required who will constantly observe the concept of balance and see the tip of the boom.

Let’s finish the article with the following questions:
-Whether the pump manufacturers not find another area to compete?
-Have the mechanical, hydraulic, electrical and electronic fields related to the pump and boom been thoroughly scanned?
-As there are several operational problems in practice is it worth to race only with boom.
-The stationary pump + seperate stationary placing boom option, where applicable, cannot be evaluated enough?
-Is it difficult for companies to lay the pipes?

There will be soon a new position to be added to the norm staff in ready-mixed concrete companies!

Considering that one of the existing staff can do the business development task, the norm staff in ready-mixed concrete companies has not radically changed for a long time. But now it seems that we will have to add one more task. This is drone operator…

Drone applications, which quickly entered almost every field, are no longer fantasy and start in daily operations of ready-mixed concrete, too. No, I’ am not yet talking about the concrete delivery with drones, but their use in logistics is just around the corner.

Drones, which have already been on construction sites for a while, are now entering the machinery inventory of concrete companies.

And of course, some questions arise related the operation of drones. Who will use the drones at readymix companies.

After the plant operator, mixer operator and pump operator, drone operator position are now on the field for concrete operations. So what will their job descriptions be and more importantly, who will provide their trainings?

About thirty years ago, I made a great contribution to operator training in the ready mixed concrete association. After holding several meetings to create the system, I also personally gave the first trainings.

Now, as a mechanical engineer, but graduated from the aviation branch and also as a father of aircraft pilot, I would also like to warn the ready-mixed concrete association for this new position.

Of course for small ready-mixed concrete companies having a machine park consisting of one plant, 10-15 mixers and a few pumps, this may seem far away. But large companies should immediately put this issue on their agenda.

At the first glance;

-It can help first inspection of the site and approach roads.

-Can guide drivers on the roads.

-Can assist the dispatcher for logistics

-It can support the safety on the road and at the site

I cannot say it can deliver the lastminute missing concrete yet, but we can say that it can deliver, for example, a necessary part for the pump or a leaking hydraulic or electronic part which may stop the machine, very quickly and just on spot.

In my opinion, the ready mixed concrete association should take action to obtain training accreditation for drone operators, at their earliest convenience!

Training of everybody who are the integral part of the dispatch is a must for team success!

– Are your drivers in the 4×100 flag race or do they run and run like a marathon and run again?

-We see it in the world cup. The team that runs a lot or the team that has the system, technique and talent, who wins?

-Do you motivate your drivers for personal success or team success?

-Are you giving them individual tour bonus? Do you think that this may create unnecessary internal competition and also invite the accidents on roads and at sites.

-Here are some studies prepared by the undersigned for system, techniques and the talent of concrete dispatch in order to work with the same spirit. Without a fundamental and knowing the algorithm of the work, no ERP software or program can bring the expected efficiency.

-Every person in the team should know the basic system in the same way and be able to put it into practice in their own field. If the drivers do not know what the dispatcher wants to know they cannot provide correct feedback. If the dispatcher does not know and feel what is happening in the field, he cannot manage the process well.

-Therefore multi-participant dispatch training for disponents as well as fleet manager, workshop manager and others who are the integral part of the team is a must for the total success!

Please call just to talk about the training…

Understanding Newton’s laws…

If you’re not taught Newton’s laws in rollover protection training, stop listening to stories. Because, in this case you will soon experience your own bad story.

Can there be a truck driver, tipper driver, tanker driver and mixer operator who does not know Newton’s laws?

Safety related trainings on trucks should cover the laws of physics.

There are many natural forces such as gravity, momentum, kinetic and potential energy, friction, centrifugal force etc. which should be clearly explained on a technical basis. Otherwise, the study remains only a motivational meeting.

-Why is tipping not a surprise for trucks?

-What does dynamic load mean for a truck?

-How affect the centrifugal force?

-Why the mixer trucks rollover easily?

-What is the cam circle, how does it affect the rollover

Adequate understanding of Newton laws will help the drivers to control the vehicle in bends and turns, decelerating and stopping, as well as other conditions encountered during the driving process.

Well, how can you explain Newton to a prospective drivers who has never taken physics lessons in his life?

Do not worry and think about it. Over the past 30 years it is my duty.

What should you do, just a call…

Could this song be describing the state of mixer drivers?

Mixer drivers are responsible for loading, transporting and unloading concrete on site and cleaning the drum and must always be in good physical condition to perform these duties.

Daily maintenance and, if in case, flat tire replacement can be added to these tasks. They also do not have to use any assistant as pump operators, to do these jobs. Mixer drivers have to do all the work alone.

Work can usually start at six in the morning and last until midnight.

Is it possible for the drivers to return home after such a job and spend time with his family, rest and socialize?

It’s obvious that a lot of effort is required from the mixer drivers, but that’s just the physical part of the job. On the other hand, since a mixer driver is always at the bottom hierarchically throughout his work, he is sometimes humiliated and insulted by the plant operator, foreman, dispatcher and site supervisors, and his efforts for these works are ignored.

I wonder if the mixer drivers really have no complaints about their position? In fact, truck drivers are proud of their profession and to be on the road. Mixer drivers are no different. They may even be glad that they are always helping to do something new as houses and buildings, unlike cargo trucks. I feel that they just as happy with their lives as in the song?

English translation:

-I have to go to the construction site.

-When I got up this morning.

-And the sun won’t come out today.

-I sit down for breakfast.

-My stomach is sick!

-That’s what my grandpa used to say.

-But now I have no more timework is calling.

-I have to go now.

-All I bring is concrete.

-I love driving.

-Give me concrete.

-Concrete.

-I can’t do anything else.

-Give me concrete.

-Give me…

-And when I’m sitting on the mixer truck.

-What a pleasure it is.

-I drive back and forth to many construction sites.

-Concrete this is my life.

-I’d like to bring you concrete.

-If you need anything then call me.

-I’ve had enough of this.

-All I bring is concrete.

-I love driving.

-All I bring is concrete.

-All I can do is concrete.

-I love driving.

-All I bring is concrete.

-Concrete.

Can taking a nap in the cab count as a rest period?

There is an old training set for mixer drivers which is disparate among the others by drawing attention to the working hours.

-How many hours can a mixer driver work in a day?

-How long can a mixer driver be at the wheel?

-Should the waiting times be counted as off-working?

-Can it be considered as a rest period while taking a nap in the cab?

Concrete operations can take 2-3 days and none-stop pouring lasts hours. People those who spend a long time in this industry know that the mixer drivers sleep standing these times.

Unlike other truck drivers, mixer drivers work in and outside the vehicle on roads and construction sites in all weather conditions. In this case, how can be applied the fatigue situation at the steering wheel to the mixer drivers.

Typical daily work of mixer drivers:

30 min.    Pretrip inspection and refueling

90 min.    Load at plant x 3 times

120 min.  Drive to job x 3 times

180 min.  At the plant x 3 times

120 min.  Drive to plant x 3 times

30 min.    On-duty lunch

30 min.    Washing and cleaning

—————————————–

600 min. (10 hours) Total working time

240 min. (4 hours) Total driving time.

If we add another tour as overtime which many companies apply and majority of mixer drivers prefer, we will get a 14 hours of total working time and 5.5 hours of driving time.

There is still not contrary to the restriction of not drive more than 4.5 hours in a total of 9 hours in a daily work for all commercial trucks.

However are the mixer drivers not tired and feel fatigue during 14 hours of working every day. How sustainable is such a working style and is this not a big risk for occupational safety?

There are some research in related subject and the findings as follows:

-Results of studies on over-the-road driver fatigue and alertness indicate that hours worked don’t necessarily translate into fatigue.

-Hours of driving (time-on-task) was neither a strong nor consistent predictor of fatigue.

-Time of day when driving took place was more important than the length of the trip.

-Fatigue was most likely to occur between midnight and dawn.

-Studies revealed that drivers could not judge their alertness.

-Researchers measured drivers’ brain-wave activity and eye movements and videotaped their facial expressions to determine when fatigue set in.

-Additionally, truck-mounted equipment recorded lane tracking, steering-wheel movements and vehicle speed data to determine when fatigue caused erratic driving.

-Driver fatigue was not as widespread as some speculated.

These studies indicate large differences in levels of alertness and performance among drivers. Also clearly demonstrates the importance of continues educating all drivers about the fatigue and dangers of drowsy driving and the warning signs of tirediness as well as all all other safety issues.

If you want to look at this topic together and supply an safety training for your mixer drivers, do not hesitate to call in order to come together.

Do you clean inside of the drum with or w/o loto.

-In the concrete industry, for some reason, hazardous energy control is carried out exceptionally for stationary facilities. Near-miss events seem to be only a matter of cement factories. It is also usually for electrical energy.

-We can see some measures in batch plants but for only central mixers. However there are bant conveyors, elevators etc in motion.

-On the other hand, there are so many precautions to be taken for the cleaning of the concrete truck drums. The truck is itself

a moving machine and the mixer drum is like a windmill in any way.

-Have you ever wondered what happens to the hardened concrete residue that builds up inside the rotating drums of those concrete mixer trucks?

-As the concrete residue inside the drum builds up, the mixer’s capacity is gradually reduced. This means you can’t transport as much fresh concrete as you could with a clean drum.

-All that dry concrete residue lining the inside of the drum weighs a lot and heavier trucks use more fuel. Fuel costs money.

-The longer the concrete residue stays in the drum and the more it builds up, the harder it is to get out.

-Considering  there are  a number of mixer trucks in concrete facilities you may be in danger while dealing with these machines not only for cleaning but also for maintenance as well as every minute in operation.

– All kind of energy may be beneficial but also dangerous. Those working with stationary or mobile machines should be aware of this fact.

-It is difficult to understand why dangerous energy is not taken into account enough in mobile machines. This is purely a matter of culture. If we leave it to the operator’s control only, we will continue to see accidents as a fate.

-I recommend you LOTO training for all stationary and mobile machines in your ready mixed concrete facilities. Let’s examine the safety rules and procedures for your batch plant, wheel loader and concrete trucks and their drums.

-If you suffer such accidents and want to draw attention of your employees  to this point  just a phone call will be sufficient to come together physically or virtually  in order to discuss the subject.
