RM140 Mini Excavator Top Type In Chisel 135mm Hydraulic Hammer Rock Road Stone Breaker

RM140 Mini Excavator Top Type In Chisel 135mm Hydraulic Hammer Rock Road Stone Breaker

Hydraulic breakers have become an important tool for hydraulic excavators, and some people have installed hydraulic breakers on excavators, backhoe loaders or wheel loaders for crushing operations.

Instructions:

1) Read the operation manual of the hydraulic breaker carefully to prevent damage to the hydraulic breaker and excavator, and operate them effectively.

2) Before operation, check whether the bolts and connectors are loose, and whether there is leakage in the hydraulic pipeline.

3) Do not peck holes in hard rock with a hydraulic breaker.

4) Do not operate the breaker when the piston rod of the hydraulic cylinder is fully extended or fully retracted.

5) When the hydraulic hose vibrates violently, stop the operation of the breaker and check the pressure of the accumulator.

6) Prevent interference between the boom of the excavator and the drill bit of the breaker.

7) Except for the drill bit, do not immerse the breaker in water.

8) Do not use the breaker as a lifting appliance.

9) Do not operate the breaker on the crawler side of the excavator.

10) When the hydraulic breaker is installed and connected to the hydraulic excavator or other construction machinery, the working pressure and flow of the hydraulic system of the main machine must meet the technical parameter requirements of the hydraulic breaker. The "P" port of the hydraulic breaker is connected to the high-pressure oil circuit of the main machine. Connection, "A" port is connected with the oil return circuit of the main engine.

11) The optimum hydraulic oil temperature when the hydraulic breaker is working is 50-60 degrees, and the maximum temperature should not exceed 80 degrees. Otherwise, the load of the hydraulic breaker should be reduced.

12) The working medium used by the hydraulic breaker can usually be consistent with the oil used in the hydraulic system of the main engine. It is recommended to use YB-N46 or YB-N68 anti-wear hydraulic oil in general areas, and YC-N46 or YC-N68 low temperature hydraulic oil in cold areas. Hydraulic oil filtration accuracy is not less than 50micro;m.

13) New and repaired hydraulic breakers must be recharged with nitrogen when they are in use, with a pressure of 2.5, ±0.5MPa.

14) Calcium-based grease or complex calcium-based grease must be lubried between the shank of the drill rod and the guide sleeve of the cylinder body, and it must be refilled once per shift.

15) When the hydraulic breaker is working, the drill rod must be pressed on the rock first, and the breaker must be started after maintaining a certain pressure, and it is not allowed to start in the suspended state.

16) It is not allowed to use the hydraulic breaker as a crowbar to avoid breaking the drill rod.

17) The hydraulic breaker and fiber rod should be perpendicular to the working surface during use, and the principle of not generating radial force is the principle.

18) When the broken object has broken or started to crack, the impact of the breaker should be stopped immediately to avoid harmful "empty hitting".

19) If the hydraulic breaker is to be stopped for a long time, the nitrogen should be exhausted, the oil inlet and outlet should be sealed, and the cutting iron should be stored in the environment of high temperature and -20 degrees.
