Hydraulic Breaker Mini Excavator
Hydraulic breaker mini excavator is an attachment fitted to excavators for demolishing rock, concrete structures and so forth. YANTAI BAICAI MACHINERY We supply a wide range of hydraulic breakers and spare parts, if you are interested in our hydraulic breaker mini excavator, please feel free to send inquiry to us, thank you.
Hydraulic Breaker Hammer Working Principle:
Hydraulic breaker hammer has become an important working tool for excavators, and some people install the hydraulic crushing hammer in the backhole loader (also known as two busy) or wheel loaders to carry out the crushing operation. Hydraulic breaking hammer, also known as hydraulic breaker or hydraulic Stone breaker.
Hydraulic Breaker without Accumulator:
Simple structure, Low failures rate
Easy maintenance, low cost and impact energy increase. Therefore, users can reduce the cost of using and maintaining two aspects at the same time.
Hydraulic Breaker with Accumulator:
In the case of single strike, the strength will be slightly larger, no space can be found during the installation and maintenance, otherwise the nitrogen will be leaked, which causes the crusher to strike weak and the accumulator diaphragm damaged.
The Function of Accumulator:
The accumulator is filled with nitrogen, which uses hydraulic hammer to reverse the remaining energy and piston during the previous blow.
The energy stored in the tank is stored at the same time, releasing energy at the same time during the second strike, increasing the hitting ability, usually not hitting the crusher itself.
The accumulator is installed in the case of energy to increase the striking force of the crusher. So there are no accumulators in small hydraulic hammer, and medium and large ones are equipped with energy storage.
Operating the Hydraulic Hammer：
* Press Chisel to the object to be broken.
* Strike vertically.
* Once object is broken, stop striking immediately.
Working in high or low outside temperatures：
High: The temperature of hydraulic oil must be ensure it close not exceed the specified temperature limits.
Low: At temperature below 0 degrees centigrade, the carrier must be warmed up prior to use, in the way described by the excavator manufacturer.
Ensure that the hydraulic oil in the carrier is at least at 0 degrees centigrade, before starting up the hydraulic hammer.
Note: The Hydraulic hammer and excavator or will not operate to full capacity unit the oil temperature has reached at least 60 degrees centigrade.
Always observe the relevant safety regulations when handing oils and greasing.
Every two hours of continuous operation lubricate the chisel with moly-based grease.
To guarantee longer life of chisel and bushing, hydraulic hammer should take high performance grease and genuine parts which is supplied by PTEROSAUR.
1. Engine’s rotation speed should be controlled under the one pre-set.
2. Don’t work continuously in hot summer, to prevent too high temperature of hydraulic oil. If oil temperature reaches 80 degrees centigrade, must stop working, until the temperature lowers down.
Feeding hot hydraulic oil to extremely cold hydrauic hammer will cause internal stresses in the unit resulting in its failure.
If grease is not supplied sufficiently, then high hear is generated due to friction at the moving parts if the hammer. The heat can cause premature wear and cracking of related parts.
Please choose No.68 hydraulic oil in winter and No.46 hydraulic oil in summer. Oil should be clean & sufficient during working. Dirty oil will cause damages to the Breaker. Please check regularly if Breaker’s cylinder, accumulator, oil pipes & hoses leak oil. If oil leaks, please replace O‐ring & oil seal in time.
Chisel, Chisel Pin & Bushing
Before each working, check if the chisel pins are in good conditions. Check regularly the clearance between bushing and chisel, too much clearance will cause piston & chisel broken. If outer diameter of chisel abrades more than 3mm, or inner diameter of bushing abrades more than 6mm, please replace new ones.
