STRUCTURE

T-SERIES

Tie Rod Back Head (Gas Chamber)

Valve

Cylinder

Accumulator

Piston

TIE ROD Front head, cylinder and back head of breaker body are tightly fixed with four tie rods. BACK HEAD Gas charging valve is built in and the inside is charged with N2 gas. VALVE Cylindrical control valve is built in the valve housing and controls piston reciprocation. CYLINDER The cylinder is the heart of the breaker containing hydraulic circuit for piston reciprocation. ACCUMULATOR (GB11F / GB14F) The accumulator compensates for pressure in the hydraulic circuit and prevents pulsation. It is not usually necessary to refill. Use N2 gas only.

Front Head PISTON Kinetic energy of the piston is converted into hammering energy after hitting the tool. The hammering energy transmitted to the tool breaks rocks.

Tool

FRONT HEAD The front head supports the whole breaker. Thrust ring and thrust bushing prevents shock from the tool. TOOL The specially heat-treated tool is directly applied to break rocks. It is in the form of a wedge, moil point, blunt, cone and wide chisel appropriate to the application. (optional)

Working principle

3

WORKING PRINCIPLE

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 to A2. When A1 changes from high to low pressure or vice versa, Piston C2 reciprocates. Inside of back head is charged with the high pressure gas and gas energy stored in the upstroke of the piston C2 effectively acts on the piston C2 during the impact.

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

2. VALVE SHIFT When cylinder low pressure port B1 is connected to cylinder change port B2, the pressure in valve change port B4 lowers. As force acting on valve C4 is the only pressure in valve high pressure chamber A3, valve C4 starts lowering. During the valve lowering stroke, valve high pressure port B3 is closed and valve low pressure port B5 is opened to the upper chamber of the piston A1 to lower the pressure in the upper chamber of the piston A1.

14 |

GB HYDRAULIC BREAKERS

Working principle

3. IMPACT When piston C2 reaches impact point, kinetic energy obtained by piston C2 during the impact stroke is transmited to the tool C3 for the impact energy required to break. At this time, as high pressure applies only to the lower chamber of the piston A2, piston C2 starts reversing. Further, as high pressure applies only to the valve high pressure chamber A3, valve C4 is remaining in the lower position.

4. UPSTROKE When cylinder change port B2 is connected to cylinder lower pressure port B1, high pressure oil applies to low pressure outlet port and valve C4 start to the down position A1 this time valve low pressure port B5 is closed and valve high pressure B3 is opened the upper chamber of the piston A1 to rise the pressure in the lower chamber of the piston A1.

A1 : Area of the upper chamber of the piston A2 : Area of the lower chamber of the piston A3 : Area of valve high pressure chamber A4 : Area of valve change chamber B1 : Cylinder low pressure port B2 : Cylinder change port B3 : Valve high pressure port

B4 : Valve change port B5 : Valve low pressure port C1 : Breaker body C2 : piston C3 : Tool C4 : Valve

5. HYDRAULIC PIPE LINES FOR EXCLUSIVE USE Operation of the hydraulic breaker requires installation of hydraulic pipe lines for exclusive use of the hydraulic breaker. As hydraulic pipe lines vary depending on base machines, our service engineer must first check the hydraulic pressure, oil capacity, pressure loss and other conditions of the base machine before installing hydraulic pipe lines. Use only genuine parts in case of the need for replacement as hydraulic pipe lines (hoses, pipes and fittings) are made of materials carefully selected in consideration of durability.

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

(3) Loosen hose plug on the breaker arm. Collect a small amount of oil flowing out at this time and put into a container. (4) Be careful to prevent mud or dust from entering oil hoses and pipe lines. Plug oil hoses with hose plug and pipe lines with union caps. Bind high and low pressure hoses with a wire to prevent them from 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 bucket operation easily contaminates the end part of hoses and pipe lines. The contaminated part must be cleaned without delay. Hydraulic oil or light oil is highly recommended.

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

3. CRITERIA OF OIL CONTAMINATION AND MALFUNCTION / General Analysis ANALYSIS ITEM

Adhesiveness

Oxidizing Level

Moisture

CRITERIA

CAUSES AND EFFECTS WHEN EXCEEDS THE CRITERIA

within ±10% (40℃ cst)

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

Less than 0.3 (mg KOH/g)

Use of a lubricating oil during long period of time under high of a lubricating(higher than 60℃) will oxidize it. Oxidizing level rises as ozidization proceeds. Sludge will be produced during the process, leading to unsatisfactory operation of the breaker, erosion of metals or obsolescence of seal materials.

Less than 0.1 (%)

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

4. CRITERIA OF MALFUNCTION BY HYDRAULIC OIL COLOR / Simple discrimination by ASTM color Hydraulic oil turns black as the breaker fails to display best performance. The old oil is assumed to be contaminated when there is a visual difference between the old and new oil color and functions begin to deteriorate when hydraulic oil turns darker than the new oil color(ASTM number) by more than two.

GB HYDRAULIC BREAKERS

Operation

1. OPERATION METHOD 1. When the tool is firmly stabilised on the rock and the breaker has been pressed down, the operation valve can be opened. While breaking, pressure must always be applied longitudinally on the tool.

Pressing

During hammering operation, apply pressure successively.

2. Close the operating valve immediately when cracks appear on the rock or when the tool begins to move out of the body of the breaker. Stop hammering immediately after the material is broken.

2. PROPER THRUST 1. To use the breaking force of a breaker effectively, a proper thrust has to be applied to the breaker. If the thrust 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 in damage 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 violently hit against the rock resulting in damage. 3. If hammering is performed under such a condition, vibrations during hammering may also be transmitted to the 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.

Operation

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 The tool is pushed up by applying the impacting power.

Pressing

34 |

GB HYDRAULIC BREAKERS

BLANK HAMMERING Since no impacting power is applied, the tool lowers.

Operation

3-2. Excess power should not be applied to the tool. The breaker and the tool assembly should not be used as a lever or a rip. It is not designed for this purpose and the tool is likely to be broken or the tool holder damaged.

3-3. Firm materials should be cracked from the edges. If the tool fails to penetrate or produce any breaking of the material after being operated in one spot for 30 seconds to one minute, then change the tool position.

Cracking from edge.

3-4. Do not operate the breaker in water and mud. - Do not operate the breaker with the components other than the tool immersed in water or mud. The piston or similar components may be rusted to result in a prematurely damaged breaker.

Do not operate in the water. Up to here. tool

- In case of operation in/under the water, use the under-water-type breaker specially/independently ordered.

GB INDUSTRIES CO., LTD.

Operation

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

Don’t hit

Find trouble at an early stage!!

3-6. Keep optimum blows. GB Hydraulic Breakers have a control valve for blows, please adjust blows with the control valve for blows according 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 are measured in the tank, an oil cooler must be fitted.

3-8. Do not move rocks. Avoid moving rocks with the side of the bracket. It is the major factor to bolts installed on the bracket breaking. It will also cause damage to the tool, boom and arm.

36 |

GB HYDRAULIC BREAKERS

Operation

3-9. Do not use tool as a lever. If breaking rocks by using tool as a lever, the bolts 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 to be 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 necessary does not strengthen hammering force but increases oil temperature to the detriment of pistons and valves.

3-12. Do not allow the breaker to drop onto break a rock. Dropping the breaker onto a rock will apply excessive force to the breaker or the base machine, causing damage to many parts of the breaker and base machine.

GB INDUSTRIES CO., LTD.

| 37

Operation

3-13. Do not hammer with base machine cylinders moved to the stroke end. Hammering with each base machine cylinder moved to it’s stroke end (fully extended or retracted) will do considerable damage to the cylinder and each part of the base machine.

3-14. Do not lift things with the breaker. Lifting materials by hanging wire in the bracket or tool not only causes damage to the breaker but also is very dangerous when operating.

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 oil temperature 30℃�40℃/80℉�105℉) before breaker operation. Follow the base machine instruction book for warming-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 Tool ② Lower bush ③ Retainer pins ④ Hydraulic seals ⑤ Side bolt ⑥ Hydraulic hoses

2-2. Replace hydraulic seals every 600 hours of actual operation. 2-3. Tool retainer When each tool retainer is excessively deformed, it is difficult to replace the tool. Therefore, every 100 to 150 hours of operation, change the face of each tool retainer which comes in contact with the tool (The two 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 changing tool pin direction, place pin with this surface on tool side.

Tool

Tool Retainer Remove burrs and swelling with grinder or the like.

When replacing, check each part for wear, breakage, scoures, etc., especially, after removing burrs and swelling on tool retainer and tool. Replace tool after grinding the worn parts of lower bush and stop pin.

2-4. Lower bush Wear Limit of Tool and Lower Bush : When the clearance between the tool and lower bush becomes large, it is strongly recommended to replace these to prevent other parts from wear. Exceeding the wear limit dimension clearance may damage other component parts, such as pistons and cylinders.

Inspection and maintenance

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 the breaker 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 the following 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 more engine rotation the blow frequency does not increase, rather the oil flows out by the relief valve. Thus oil temperature will rise and the continued ratio becomes high. NB : Indicated Engine Rotation While 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 tool holder, 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-ing packing, 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 pushed out. 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.
