Hydraulic Rock Splitter - Powerful economic way to split rock and demolish concrete
01 Jun 2017
Hydraulic rock and concrete splitters provide a powerful and extremely cost-effective alternative to other conventional demolition techniques. Hydraulic splitting means controlled splitting, and this method eliminates shock waves, vibration,dust and noise that large impact tools usually produce. Prodrill rock and concrete hydraulic splitters have been used with great success in over 55 countries for the past 15 years. The high quality, reliability and durability of the equipment is unsurpassed.
How the Hydraulic splitter works?
Conventional demolition techniques destroy rock and concrete by using an external force. However, because of their compression strength, these materials are highly resistant to impact forces. For optimum results, one should adopt a splitting technique that works from the inside of the material, because rock and concrete have a lower tensile strength. The hydraulic splitters were developed to do just this and work according to a safe and proven wedge principle.
Firstly, a hole is drilled to a specified diameter and depth using an ordinary rock drill. Then the wedge set is inserted into the hole with the wedge in a retracted position. The hydraulic pressure then forces the wedge between the two counter wedges, pressing them against the walls of the drilled hole. The effective splitting force of up to 413 tons or 4048 kn breaks concrete and rock from the inside, breaking thinner iron rods at the same time.
Blasting usually requires work stoppages and the installation of protective walls and other safety equipment. This costs both time and money. With high-performance rock and concrete splitters, blasting is no longer necessary. Therefore, there is no potential danger to the workforce or passers-by, and other work in the immediate surroundings can continue unaffected.
Hydraulic splitting means controlled demolition. The entire force developed is always under full control. There is no danger of flying debris, vibrations or even explosions.
When using the hydraulic splitting techniques, there are no unpleasant side effects like vibrations and dust. Even noise emission is extremely low, which means that, this demolition technique is particularly environmental friendly. That is why the splitter is indispensable in densely populated areas or inside building.
Thanks to the extremely robust design, the rock and concrete splitter can withstand even the toughest conditions. Its durability is quite exceptional. Therefore, next to no maintenance is required. Yet another cost-saving factor.
Splitters and pump units are easy to transport. Operators no longer depend on heavy machinery like excavators, for their transport to the demolition site. Therefore, even the smallest workplace is no longer a problem.
Easy to Use
The splitters are extremely easy to operate. The light weight design enables an operator to work on a splitting job single-handedly. Even unskilled workers can learn to use Hydraulic splitter in a very short time.
Hydraulic rock and concrete splitters enable you to work with a precision that cannot be achieved when using conventional demolition methods.The desire direction of the split and size of material to be removed can be determined before hand. The portion of a structure that ought to remain intact is not affected by the splitting process.
A complete rock and concrete splitter comprises 3 components:
1.One or several splitting cylinders
2.One hydraulic pump unit
3.One set of high and low pressure hoses
The hydraulic splitting cylinder consists of a control valve, a cylinder, a front head and a wedge set (1 wedge and 2 counter wedges). The entire cylinder is made of highest quality aluminium and steel so that although the equipment is light. It is still extremely durable. The counter wedges are also coated with a hard metal(carbide) layer in a specially developed harding process. This makes them more resistant to very high pressure and force.
Most suitable for:
Secondary splitting of large boulders
Enlarging work in underground mining
Pipe jacking/micro tunneling
Demolition work at closed spaces and places that are difficult to access
Demolition work at extremely cramped space
For cutting concrete piles
For demolition of factory chimneys
Secondary splitting of concrete slabs
Demolition reinforced concrete
Rock demolition in trenching
Secondary splitting of rocks
Enlarging work in underground mining and under water demolition
Demolition of walls and wall opening.
