¿Qué es la sílice cristalina?
La sílice, a menudo conocida como cuarzo, es un mineral muy común. Se encuentra en muchos materiales comunes en sitios de construcción, incluyendo tierra, arena, hormigón, mampostería, roca, granito y materiales de paisajismo. El polvo creado al cortar, moler, perforar o molestar estos materiales puede contener partículas de sílice cristalinas. Estas partículas de polvo son muy pequeñas e invisibles a simple vista. Cuando se inhala, incluso en cantidades muy pequeñas, el polvo de sílice puede causar graves peligros para la salud. Cada exposición a la sílice añade daño pulmonar.
¿Qué es la Silicosis?
La silicicosis es una enfermedad pulmonar discapacitante, irreversible y, a veces, fatal. Cuando un trabajador inhala sílice cristalina, los pulmones reaccionan desarrollando nódulos duros y cicatrizando alrededor de las partículas de sílice atrapadas. Si los nódulos se vuelven demasiado grandes, la respiración se vuelve difícil y puede resultar la muerte. No hay cura para esta enfermedad, pero es 100% prevenible.
Cumplir con las normas
Ya sea que esté preocupado por la salud de sus empleados, su salud, el cumplimiento o el aumento de la productividad, Bosch ha desarrollado sistemas de protección PRO+GUARD. Con el fin de avanzar hacia el cumplimiento y la protección, es fundamental que cada componente del sistema esté diseñado para quitar eficazmente el polvo. Los sistemas de recogida de polvo Bosch pueden reducir el polvo transportado por el aire, ayudando a crear un entorno de trabajo más seguro y saludable.
Protéjase a sí mismo y a los demás
La Administración de Seguridad y Salud Ocupacional (OSHA) ha emitido una regla final para frenar el cáncer de pulmón, la silicosis, la enfermedad pulmonar obstructiva crónica y la enfermedad renal en los trabajadores de Estados Unidos al limitar su exposición a la sílice cristalina respirable. Mientras se utilizan herramientas eléctricas con un accesorio de polvo y extractores de polvo con el filtro adecuado, la exposición a la sílice se puede reducir drásticamente. La nueva norma entró en vigor el 23 de junio de 2016, y los empleadores deben cumplir con todas las obligaciones de la norma antes del 23 de junio de 2017.

En primera llegó antes de tiempo y excelentes condiciones, ya en el uso sorprende su fuerza y desempeño, quitamos 14mts cuadrados de concreto con un espesor de 10cm, la herramienta x si sola no hubiera podido ya que no es la indicada, nos asistimos de un marro para primero debilitar o cuartear un poco la placa de concreto que repito tenia un espesor de 10cm, ya de lo demás se encargo el jugetito que se muestra en las fotos, ya por último y no menos importante es de que x algo BOSCH es líder en ventas, pues 7 de cada 10 herramientas de este tipo son BOSCH y como no si fueron los que lo inventaron!!

This rotary hammer is a brute but easy on your body. I used it with a 6” chisel to clear 3/8 inch mortar off of 40 sq. ft. of concrete like I was scraping mud off my boots. It is up to almost any task as long as you use it properly. Make sure t keep the chuck and bit well greased and don’t force it. Let the tool do the work. Moderate pressure and the right angle is all that are needed.If you don’t get a tool that does the work, YOU end up picking up the slack. This tool does the work. It will handle any thing you can throw at it, as long as you know what your are doing.

Lo recomiendo ampliamente, trabaja el concreto sin mucho esfuerzo y no sientes tan duro el golpeteo cuando usas los cinceles para demoler,, eso si es pesada pero la calidad es incomparable!

aunque es un poco mas pesado de lo previsto, es un monstruo mucho poder para trabajos de demolicion mediana, concreto solido facil, ladrillo y otros muy facil. Ranuras tambien excelente solo hay que tener fuerza para no perder la lineamuy bueno solo va poco tiempo pero lo he usado en diferentes actividades

Have had this unit for over a yr for concrete work and demolition.. Can't say enough about it. Bosch is in my opinion the best when it come's to demolition hammer's.. Every major concrete contractor i know 9 and i know quite a few big player's).. All use Bosch a few have the yellow and black one's. But there generally not as reliable.

I bought this rotary hammer primarily to use as a demolition hammer for a month and then to have around afterwards for whatever other uses I might have. I thought I might have made a mistake as the going was pretty slow at first when I started to remove concrete from a 65 year old floor. But I soon realized I was trying to chip out too big of a piece. It works better and quicker to go at it from about an inch or inch and a quarter from edge of slab and especially if you first take an angle into the face of the edge of the slab and then come down from the top. The other big difference in speed I've found so far is to whack the slab a few times with a heavy sledge hammer like once for every square foot or so, then the pieces just come out easily with this tool.It's heavier than I thought it would be.It gets surprisingly hot where the chisel goes into the chuck. The lower adjustable handle seems a bit weak and slips a little even when really tight. The lock on switch only seems to work in hammer-only mode, not when used as a hammer drill which is probably a sensible safety feature.This tool runs smoothly and never sounds laboured. Great vibration absorption. The slip clutch does work when drilling but doesn't cut in too easily. The case it comes in is a lot more compact than the case for a smaller rotary hammer by Makita and it has a handy storage spot for chisels which the Makita case doesn't have.I wish I'd bought this thing ten years ago instead of renting one when absolutely necessary.

Coming from mainly using a Bosch Bulldog with SDS-plus, this hammer is a massive step up in power and material removal, when it's required. This particular hammer is a bit heavy, but just light and nimble enough that it can be used for good periods of time, and fairly precisely. I've used this for at least 10+ hours of actual runtime now, and I can't come up with many negatives. I can't see many people needing this for "home use", versus professional, but go for if you can get your money out of it, etc..Overall build quality is great, as expected. Unless it ever changes, this unit is made in Germany. The case is large and adequate for a hard case. The straight handle that is featured on this unit is more ideal for drilling compared to the hammer only model's handle, but I have only used it for demolition and it does fine.The trigger stays on during hammer-only use, and motor speed can be adjusted. This is nice compared to holding a trigger for long periods and the motor speed is very useful for all of the potentially endless applications. Sometimes too much speed results in bouncing off/out of concrete, brick or other materials, and a lower speed works better. Not to mention the speed adjustment is necessary for many drilling applications.The anti-vibration features work very well. You feel so little compared to how much work is being done. Regarding vibration, compared to say the smaller units (Bulldog) which don't have anti-vibration, this unit is actually less fatiguing.The SDS system of course works great, SDS max bits are much larger than SDS plus bits.Overall I'm happy with this unit. It is high quality, powerful and works very well.

I had previously purchased a lesser model (RH228VC) to demo a brick wall that I couldn't just take a sledge hammer to but I immediately found it to be very underpowered for the task so I returned it to get the 11264EVS and I'm glad I did. The 11264EVS is a beast! It made light work of demoing a strong brick wall with no arm/wrist fatigue because of its amazing vibration absorption tech. I couldn't wait to finish the job the next day so I could use it again.Pros:-Very powerful and feels solidly built (it's heavy)-Vibration absorption is incredible-Vario setting to rotate the bit and lock it there-Trigger Lock-Takes SDS Max bits and SDS-Plus adapter available separately-Very solid cord with pivoting attachment pointCons:-Easy to activate trigger lock when you just want variable-Top metal housing gets very hot to the touch after extended runtime-No drill-only mode-Adjustable handle feels a little flimsy-No rubber grommets on its side so the coated metal housing gets a beating just by putting it down. Coating on the metal seems to chip.
