What is a Hydraulic Hammer?
Hydraulic hammer, also known as demolition hammer or a hoe ram, is usually used for excavation and demolition projects. It is a robust attachment for excavators for demolishing concrete structures or rocks. It can be mounted on excavators and other carriers like skid steer loader, backhoe loader, wheel loader, mini-excavator, and other machinery.
Typical Applications for Hydraulic Hammer Attachments
- Building demolition.
- Gardening: concrete crushing, & rock crushing.
- Mining: Mountains, quarrying, crushing, secondary crushing.
- Metallurgy, slag cleaning, ladle furnace demolition.
- Railway: tunnel, bridge, mountain down.
- Highway: highway repair, foundation excavation.
- Other: ice breaking.
Structure of a Hydraulic Breaker Hammer
A hydraulic breaker hammer has three significant components: back head (nitrogen chamber), cylinder assembly,and front head.
Back Head (Nitrogen Chamber).The backhead is the chamber where nitrogen is stored. When placed under high pressure, the nitrogen-filled chamber acts like a damper upon the return piston-stroke. It also serves as an impact enhancer when the piston travels down.
Cylinder Assembly. The cylinder assembly is the central part of a hydraulic breaker hammer. It essentially consists of a piston, a cylinder, and a control valve. There are only two moving parts in the hydraulic breaker hammer, and both are found in the cylinder assembly; the piston and the valve. The piston goes up and down and hits the tool while the valve rotates to control the path of the oil. It is where movement happens and where hydraulic power is generated.
Front Head.It is where the piston attaches with the chisel (or working tool). The chisel is set with bushes and pins, which are the parts that need to be replaced often. The front head reaches the working surface directly, and a box-type housing protecting it from wearing and leads to longer service life.
When breaking concrete and rock, nothing meets the power of a Hammer Breaker attachment, accomplishing large jobs quickly; this attachment provide excellent efficiency. Although there are many hammer breakers available in the market today, there is one that stood out among the others because of its durability and high performance-cost ratio. If you plan to purchase a Hydraulic Hammer attachment for your machine, read on to learn more about the best attachment available.
This Hydraulic Breaker Hammer attachment from Blue Diamond (a trusted and reliable company widely recognized in the global attachments industry since 1995) took five years to be developed after thorough research and study. The design offers technology, reliability, simplicity, service support, and ease of setup. No more downtime, so you get started on whatever job right away!
It comes with a ‘Monoblock’ housing in which the piston operates. Its housing is one piece, so it doesn’t use four tie-rods to hold it together like other brands. Tie-rods are famous for stretching, which eventually breaks, causing mass damage to the tool. The monoblock housing has sleeves inside to protect it from damage; if damaged, they are convenient and affordable to replace. Some manufacturers that use monoblock technology do not use sleeves, making repair very costly. It is also engineered with the most advanced technology that regulates incoming and outgoing flows to specified amounts, not needing to adjust the flow and pressure every time using the breaker.
Proper use of Hydraulic Hammer Attachments
Proper maintenance of the hydraulic hammer guarantees working efficiency and long service life.Constant and proper lubrication (avoid over-greasing)
- Regular repositioning of the tool to avoid heating
- Introducing the tool in small steps
- Positioning the tool accurately (90 degrees to the surface)
- Avoiding using the tool like a crowbar and moving away rock
- Moving the attachment slightly every so often to allow dust to escape between break site and tooltip
- Avoiding putting undue stress on the tool and driving it beyond its limitations
- Avoid pushing or moving rocks with the tool
If these factors are maintained, the tool will last a lot longer. It will save you money in the long run as well.
What makes a Good Hydraulic Breaker Hammer
- Easy to locate and control;
- Made to fit excavators;
- Reliable Company to provide parts.
- Made in the USA for access to warranty.
A hydraulic breaker hammer must mount with a suitable size carrier. The right match can optimize efficiency while protecting your machine. The hydraulic hammer is adaptable enough to work in various applications, so it is essential to match your machines with the intended project.
