Hydraulic hammer breaker misunderstandings about the operation(2)

Good quality Heavy Duty Excavator Bucket for sales
We tried our first order in 2018, which was two years after I exchange my business card with Alice in 2016 Bauma conexpo India. Our supplier didn't finish our order on time, and it will cause around 100,000 USD lose to us. That's when we tried Huitong the first time. Huitong is good at dealing with rush orders, and the quality is very good.

I work with Huitong the first time when I started my importing business. I've got tons of market insights from Jeremy. He is such a good friend being very tolerant to my bad temper. In 2017, Jeremy helped me handle a problem of bill of lading, which is caused by me. Huitong always emphasize that we should deal with the problem as soon as it occurs.

Hydraulic hammer breaker misunderstandings about the operation(2)
Hydraulic hammer breaker misunderstandings about the operation(2)
  1. The best hydraulic oil temperature when the hydraulic hammer breaker is working is 50-60 degrees, and the maximum temperature should not exceed 80 degrees. Otherwise, the load on the hydraulic breaker should be reduced.


  1. 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. The hydraulic oil filtration accuracy is not less than 50μm.


  1. New and repaired hydraulic hammer breakermust be filled with nitrogen again when they are used, and the pressure is 2.5, ±0.5MPa.


  1. The gap between the shank of the drill rod and the guide sleeve of the cylinder must be lubricated with calcium-based grease or composite calcium-based grease, and it must be filled once per shift.


  1. It is not allowed to use the hydraulic hammer breaker as a crowbar to avoid breaking the drill rod. Do not use the guard plate of the breaking hammer as a tool for pushing heavy objects. Since the backhoe loaders are mainly small machines, they are light in weight. If you use it to push heavy objects, the breaking hammer will be damaged in the slightest, and the boom of the main engine will break if it is heavy. , and even a host overturn accident.

  1. When in use, the hydraulic breaker and the fiber rod should be perpendicular to the working surface, and the principle is that no radial force is generated.


  1. When the hydraulic breaker is working, the drill rod must be pressed on the rock first, and the breaking hammer must be maintained after a certain pressure is maintained. It is not allowed to start in the suspended state.


  1. When performing crushing operations, do not use the drill rod by shaking it, otherwise the main body bolts and the drill rod may be broken; do not let the breaker fall quickly or hit hard stones hard, which will cause damage due to excessive impact. Damage to the breaker or the host.


  1. When the object to be crushed has broken or started to crack, the impact of the crusher should be stopped immediately to avoid harmful “air strike”. Continuous aimless impact will cause damage to the precursor of the breaker and loosening of the main body bolts, and in severe cases, the main machine itself can be injured.


  1. If the hydraulic hammer breakeris to be stopped for a long time, the nitrogen should be exhausted, and the oil inlet and outlet should be sealed. Do not store it at high temperature or below -20 degrees.

Excavator crushing technology is a skill that every operator should master. Under the premise of correct operation of the hydraulic hammer breaker, it can not only improve the working efficiency of the breaker, but also prolong its service life.
