rock splitter wedges for darda c12

Description

rock splitter wedges for Darda C12

The wegde is uesd on Darda C12N splitter, contains one central wedge and two feathers. The unit is inserted into a pre-drilled hole with the wedge in a retracted position. And then the feathers are pushed aside causing the material to split.

• Splitting force up to 413 tons (4048 kn) • Dust free • Quiet performance • Also applicable at places of difficult access • Vibration free • Easy handling • Easy to transport • Splits in seconds • Controlled splitting • Dimensionally accurate working

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, vibrations, dust and noise that large impact tools usually produce. DARDA rock and concrete splitters have been used with a great sucess in over 80 countries for the past 40 years. The high quality, reliability and durability of the equipment is unsurpassed

How the splitter works Conventional demolition techniques destroy rock and concrete by using an external force. However, because of their compressive 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 an concrete have a lower tensile strength. The DARDA hydraulic splitters were developed to do this and work according to a safe and proven wedge principle:
How the splitter works

Conventional demolition techniques destroy rock and concrete by using an external force. However, because of their compressive 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 an concrete have a lower tensile strength. The DARDA hydraulic splitters were developed to do this and work according to a safe and proven wedge principle:
First

First of all, a hole is drilled to a specified diameter and dept using an ordinary rock drill. Then the wedge set is inserted into the hole with the wedge in a retraced 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.

Advantages
Economical Blasting usually requires work stoppages and the installation of protective walls and other safety equipment. This costs both time and money. With DARDA high-performance rock and concrete splitters, blasting is not longer necessary. Therefore, there is no potential danger to the workforce or passers-by, and other work in th immediate surroundings can continue unaffected.

Safe Hydraulic splitting means controlled demo- lition. The entire force developed is always under full control. There is no danger of flying debris, vibrations or even explosions.

Environmental-friendly When using the DARDA hydraulic splitting technique, there are unpleasant side effects like vibrations and dust. Even noise emission is extremely low, which means that, all in all, this demolition technique is particularly environmental-friendly. That is why the DARDA splitter is indispansable in densely populated areas or inside buildings.

Durable Thanks to the extremely robust design, the DARDA 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.

Autonomy DARDA splitters and pump units are easy to transport. Operators no longer depend on heavy machinery, e.g. excavators, for their transport to the demolition site. Therefore, even the smallest workplace is no longer a poblem.

Easy to use The splitters are extremely easy to operate. The lightweight design enables an operator to work on a splitting job single-handedly. Even unskilled workers can learn to use the DARDA splitter in a very short time.

Controlled demolition DARDA hydraulic rock and concrete splitters enable you to work with a precision that cannot be achieved when using conventional demolition methods. The desired direction of the split and size of material to be removed can be determined beforehand. The portion of a structure that ought to remain intact is not affected by the splitting process.

Technical Details

A complete DARDA rock and concrete splitter compromises 3 components: 1. one or several splitting cylinders 2. one hydraulic pump unit 3. one set of high- and low-pressure hoses.

Hydraulic splitting cylinder

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 hardening process. This makes them more resistant to very high pressure and forces.
