STRUCTURE 2

TIE RODFront head, cylinder and back head of breakerbody are tightly fixed with four tie rods.

BACK HEADGas charging valve is built in and the inside ischarged with N2 gas.

VALVECylindrical control valve is built in the valvehousing and controls piston reciprocation.

CYLINDERThe cylinder is the heart of the breaker con-taining hydraulic circuit for piston reciprocation.

ACCUMULATOR (GB11F / GB14F)The accumulator compensates for pressure inthe hydraulic circuit and prevents pulsation. It isnot usually necessary to refill. Use N2 gas only.

PISTONKinetic energy of the piston is converted intohammering energy after hitting the tool. Thehammering energy transmitted to the tool breaksrocks.

FRONT HEADThe front head supports the whole breaker. Thrust ring and thrust bushing prevents shockfrom the tool.

TOOLThe specially heat-treated tool is directly appliedto break rocks. It is in the form of a wedge, moilpoint, blunt, cone and wide chisel appropriate tothe application. (optional)

WORKING PRINCIPLE3

T-SERIES

The relation between the area (A1) affecting the pressure from the upper chamber of the piston and the area(A2) affecting the pressure from the lower chamber of the piston is A1> A2 and high pressure always applies toA2. When A1 changes from high to low pressure or vice versa, Piston C2 reciprocates. Inside of back head ischarged with the high pressure gas and gas energy stored in the upstroke of the piston C2 effectively acts onthe piston C2 during the impact.

1. POWER STROKEWhen piston C2 reaches top dead center, high pressure oilfrom valve high-pressure port B3 applies to upper chamberof the piston A1 to change the piston stroke from upstroke toimpact.At this time the relation between the area(A3) affecting thepressure from valve high pressure changes and thearea(A4) of the valve change chamber is A4 > A3. The highpressure always applies to A4 and valve C4 remains in theupper position.

2. VALVE SHIFTWhen cylinder low pressure port B1 is connected to cylinderchange port B2, the pressure in valve change port B4lowers. As force acting on valve C4 is the only pressure invalve high pressure chamber A3, valve C4 starts lowering.During the valve lowering stroke, valve high pressure portB3 is closed and valve low pressure port B5 is opened tothe upper chamber of the piston A1 to lower the pressure inthe upper chamber of the piston A1.

Working principle


Working principle

3. IMPACTWhen piston C2 reaches impact point, kinetic energyobtained by piston C2 during the impact stroke is transmitedto the tool C3 for the impact energy required to break. At thistime, as high pressure applies only to the lower chamber ofthe piston A2, piston C2 starts reversing. Further, as highpressure applies only to the valve high pressure chamberA3, valve C4 is remaining in the lower position.

4. UPSTROKEWhen cylinder change port B2 is connected to cylinderlower pressure port B1, high pressure oil applies to lowpressure outlet port and valve C4 start to the down positionA1 this time valve low pressure port B5 is closed and valvehigh pressure B3 is opened the upper chamber of the pistonA1 to rise the pressure in the lower chamber of the pistonA1.

Operation of the hydraulic breaker requires installation of hydraulic pipe lines for exclusive use of thehydraulic breaker. As hydraulic pipe lines vary depending on base machines, our service engineer mustfirst check the hydraulic pressure, oil capacity, pressure loss and other conditions of the base machinebefore installing hydraulic pipe lines. Use only genuine parts in case of the need for replacement ashydraulic pipe lines (hoses, pipes and fittings) are made of materials carefully selected in considerationof durability.

5. HYDRAULIC PIPE LINES FOR EXCLUSIVE USE



WARNING

THE HYDRAULIC SYSTEM TO THE BASE MACHINE MUST BE CHECKED BY AN AUTHORIZED

SERVICE ENGINEER BEFORE FIRST USE AND AFTER ANY MODIFICATIONS.

(2) Turn the stop valve (installed at the end ofthe boom arm) 90。to the “off” position toprevent hydraulic oil from flowing out.

6. INSTALLATION & REMOVAL OF THE HYDRAULIC BREAKER

Wood blockPosition of the base machine for installation andremoval of the hydraulic breaker

When the bucket and breaker operations are performed alternately, the bucket and breaker can beeasily exchanged by the hydraulic hoses and two pins. There is however, a risk of hydraulic circuitcontamination. Therefore, install and remove as follows.


(1) Remove tool from breaker.(2) Remove breaker from excavators/backhoes.(3) Transport breaker and tool on other transporter.

7. TRANSPORT OF BREAKER

(3) Loosen hose plug on the breaker arm. Collect a small amount of oil flowing out at this time and putinto a container.

(4) Be careful to prevent mud or dust from entering oil hoses and pipe lines. Plug oil hoses with hoseplug and pipe lines with union caps. Bind high and low pressure hoses with a wire to prevent themfrom getting muddy.

(5) To remove the breaker, pull out pins in the bucket link and arm. When leaving the breaker outdoors,set the breaker on wood blocks and cover with sheets.

(6) When leaving the removed breaker for a long period of time- Clean the exterior of the breaker.- Detach tool from the front head and spray with rust preventive oil.Bleed N2 gas from the back head before pushing piston into cylinder.

- Apply grease to each part of the breaker and then install tool again.

(7) To install the hydraulic breaker, reverse the aforementioned removal procedures. The bucketoperation easily contaminates the end part of hoses and pipe lines. The contaminated part must becleaned without delay. Hydraulic oil or light oil is highly recommended.

WARNING : Do not approach tool, as rod may fly out due to the N2 gas pressure.



- Uner water operation of the breaker is possible to pour air into the striking area between the pistonand the rod.

- For the sake of underwater operation, the piston adatper is supplied as a standard part.- For the sake of underwater operation, breaker is installed the air supply kit separately.- Underwater usage of the breaker without the underwater kit and air compressor will cause seriousdamage to the hydraulic breaker.

INSTALLING THE AIR SUPPLY KIT1) Clean the air check valve hole on the side of the cylinder.2) Remove the air check valve with the standard tool.3) Apply the O-ring to the cylinder’s air check valve hole and install it.4) Connect the hose to the air check valve hole and install it.5) Before underwater operation, the breaker get into water pouring air into air check valve.

Oxidizing Level

CAUSES AND EFFECTS WHEN EXCEEDS THE CRITERIA

Adhesiveness rarely decreases soley because of hydraulicoil. Entry of different kind of oil may reduce theadhesiveness which contributes to rising oil temperature,wear and stretch of bearings and gears and malfunction ofhydraulic oil.

Use of a lubricating oil during long period of time underhigh of a lubricating(higher than 60℃) will oxidize it.Oxidizing level rises as ozidization proceeds. Sludge willbe produced during the process, leading to unsatisfactoryoperation of the breaker, erosion of metals orobsolescence of seal materials.

Moisture causes rust, wear and stretch. Moisture of 0.3%gathers a considerable amount of rust and considerableamount of rust moisture of 0.5% or more will causedamage to the machine.

Hydraulic oil turns black as the breaker fails to display best performance. The old oil is assumed to becontaminated when there is a visual difference between the old and new oil color and functions begin todeteriorate when hydraulic oil turns darker than the new oil color(ASTM number) by more than two.

Operation

2. PROPER THRUST

1. To use the breaking force of a breaker effectively, a proper thrust has to be applied to the breaker. If thethrust is insufficient, a hammering energy of the piston will not be efficiently used for breaking rocks. Thus,the hammering force applies shock to the breaker body, arm and boom of the base machine, etc, resulting indamage to those parts.

2. On the other hand, if thrust is excessive and breaking is performed with the front of the base machine raised,the machine may suddenly tilt forward at the moment the rock is broken and the breaker body may violentlyhit against the rock resulting in damage.

3. If hammering is performed under such a condition, vibrations during hammering may also be transmitted tothe tracks, and therefore, hammering in such a manner should be avoided to also protect the tracks. Further,during hammering, take care to always apply a thrust to the breaker. Do not hammer with no thrust applying.

1. OPERATION METHOD

1. When the tool is firmly stabilised on the rock and thebreaker has been pressed down, the operation valve canbe opened. While breaking, pressure must always beapplied longitudinally on the tool.

2. Close the operating valve immediately when cracksappear on the rock or when the tool begins to move out ofthe body of the breaker.

Pressing

During hammeringoperation, applypressuresuccessively.

Stop hammeringimmediately afterthe material isbroken.


3. PRECAUTIONS IN OPERATION

3-1. Avoid blank hammering.

To prevent blank hammering, the impacting power must be always applied in longitudinal direction to the tool.

Pressing

Pressing

Pressing

CORRECT BLANK HAMMERING

Pressing

The tool is pushed up by applyingthe impacting power.

Since no impacting power isapplied, the tool lowers.

Operation


Operation

Up to here. tool

Do not operatein the water.

3-2. Excess power should not be applied to the tool.

The breaker and the tool assembly should notbe used as a lever or a rip. It is not designedfor this purpose and the tool is likely to bebroken or the tool holder damaged.

3-3. Firm materials should be cracked from the edges.

If the tool fails to penetrate or produce anybreaking of the material after being operated inone spot for 30 seconds to one minute, thenchange the tool position.

Cracking from edge.

3-4. Do not operate the breaker in water and mud.

- Do not operate the breaker with thecomponents other than the tool immersed inwater or mud. The piston or similarcomponents may be rusted to result in aprematurely damaged breaker.

- In case of operation in/under the water, usethe under-water-type breakerspecially/independently ordered.


3-5. Operate carefully not to hit the excavator with the tool.

3-6. Keep optimum blows.

GB Hydraulic Breakers have a control valve for blows, please adjust blows with the control valve for blowsaccording to the field condition.

3-7. Working in high temperature conditions.

Check the oil temperature constantly to ensure it does not exceed 175℉(80℃). If higher temperatures aremeasured in the tank, an oil cooler must be fitted.

Operation

Don’t hit

Find trouble at an early stage!!

3-8. Do not move rocks.

Avoid moving rocks with the side of thebracket. It is the major factor to boltsinstalled on the bracket breaking. It willalso cause damage to the tool, boom andarm.


Operation

3-9. Do not use tool as a lever.

If breaking rocks by using tool as a lever, thebolts and tool may break.

3-10. Do not continue to hammer for more than one minute.

When rocks are not broken after more than one minute of hammering at the same point, change the place tobe hammered. Extended hammering at the same place causes the tool to wear out excessively.

3-11. Operate breaker at proper engine speed.

Break rocks at the specified engine speed.Raising engine speed more than necessarydoes not strengthen hammering force butincreases oil temperature to the detriment ofpistons and valves.

3-12. Do not allow the breaker to drop onto break a rock.

Dropping the breaker onto a rock will applyexcessive force to the breaker or the basemachine, causing damage to many parts ofthe breaker and base machine.


Hammering with each base machine cylindermoved to it’s stroke end (fully extended orretracted) will do considerable damage to thecylinder and each part of the base machine.

3-13. Do not hammer with base machine cylinders moved to the stroke end.

Lifting materials by hanging wire in the bracketor tool not only causes damage to the breakerbut also is very dangerous when operating.

3-14. Do not lift things with the breaker.

Operation

3-15. Warm up base machine engine prior to operation.

Especially in winter, the base machine engine should be warmed up for five to ten minutes (about oiltemperature 30℃�40℃/80℉�105℉) before breaker operation. Follow the base machine instruction book forwarming-up of the engine.

3-16. Do not touch the tool during hydraulic breaker operation.

During breaker operation, the breaker parts can reach high temperatures and thus should not be touched.

2. WEARING PARTS

2-1. The following items are considered as wearing parts.When damaged or worn, it is highly recommended to repair/replace these items.① Tool② Lower bush③ Retainer pins④ Hydraulic seals⑤ Side bolt⑥ Hydraulic hoses

2-2. Replace hydraulic seals every 600 hours of actual operation.

2-3. Tool retainerWhen each tool retainer is excessively deformed, it is difficult to replace the tool. Therefore, every 100 to150 hours of operation, change the face of each tool retainer which comes in contact with the tool (Thetwo faces of each pin can be used).If the tool you use is not a genuine part, we can not guarantee the performance of the breaker parts.

When replacing, check each part for wear, breakage, scoures, etc., especially, after removing burrs andswelling on tool retainer and tool.

Replace tool after grinding the worn parts of lower bush and stop pin.

When changing tool pin direction, place pin with this surface on tool side.

Remove burrs and swellingwith grinder or the like.

Tool Retainer

2-4. Lower bushWear Limit of Tool and Lower Bush :When the clearance between the tool and lowerbush becomes large, it is strongly recommended toreplace these to prevent other parts from wear.Exceeding the wear limit dimension clearance maydamage other component parts, such as pistonsand cylinders.

3. OPERATIONAL PRESSURE

If the operating pressure of the breaker is regular and the pressure of the excavator itself is regular,pressure does not need to be applied by attaching a relief valve to the high pressure line of the breaker.Please get the help of the service department for applying pressure.If the pressure is over regular pressure the breaker gets more impact which makes it a problem on thebreaker and the excavator.

4. OIL TEMPERATURE

The oil temperature will vary depending on operational conditions but it should range 50�80℃.If it is over 80℃ it makes the accumulator rubber and o-ring’s life span shorter. Be cautious of thefollowing to avoid the rise in oil temperature.

1. Avoid continuous blowing at the same point over one minute.2. Keep the indicated engine rotation.

The amount of oil needed in the breaker within the operational pressure is regular. In spite of moreengine rotation the blow frequency does not increase, rather the oil flows out by the relief valve. Thusoil temperature will rise and the continued ratio becomes high.NB : Indicated Engine RotationWhile hammering the breaker, if the engine rotation increases to some degree, it ceases to increase.“This stage of rotation is the indicated engine rotation.”

3. Keep the cooler clean.Keep the cooler clean to avoid falling a cooling effect.

5. OIL LEAKAGE

Check for oil leakages periodically. Minimum oil leakage, out of drain plug and between tool and toolholder, should be disregarded as it helps keep the tool greased.In cases of a lot of leakage check and replace the packings. Apply the working oil to the work-ingpacking, o-ring, gas-seal, dust seal and packing groove.Applying grease (recommend cylinder grease) to o-ring is especially effective.

WHEN REPLACING THE PACKINGS THE FOLLOWING SHOULD BE INSPECTED.

1. Check if there are any scratches on the packings. Check that they are well pressed and not pushedout.

2. Be cautious of dirt of flow.3. If the working packing gets damaged, check the packing and stroke piston.4. And also check if the dust seal has been pushed out or wrongly connected or if there are any

scratches in the cylinder.5. When the working packing and gas-seal is damaged oil will leak out.

Replace each packing and o-ring. Contact your local service dealer for assistance.
