How to use the breaker hammer correctly for micro excavation and crushing?

The mini excavator built by LEMG Heavy Industry has won unanimous recognition from consumers with its own product advantages and has a very high influence in the industry. As an old company that has specialized in R&D and production for many years, the most important thing to thank in this process is The trust of consumers has allowed LEMG to go out of Shandong and go global. Many customers who purchase excavators will not only use them for weeding, but also for crushing operations. The following editor will tell you about the precautions for mini excavator crushing.

Please warm up the machine before carrying out crushing operations with the mini excavator. Before carrying out the crushing operation, please warm up the machine for 10 minutes in advance. Especially in winter, this operation will help the smooth progress of the crushing operation.

The crushing machine of the mini excavator moves forward gradually and crushes in stages. Gradually move the impact point from the edge to the inside. Do not try to break larger blocks at once. If it cannot be broken within 30 seconds, it should be broken in batches. The impact distance of each crushing is too large and it is difficult to achieve good results. Crusher Working for more than 30 seconds may cause mechanical damage. When the crushing object is a larger block, please crush from the edge. Regardless of the hardness of the object, it is generally easier to crush from the edge.

Do not use the breaker to lift items when the mini excavator breaks them, and do not use the breaker to lift items. This operation not only causes damage to the drill rod and breaker, but also poses safety risks. Do not use the breaker for underwater operations. If the piston and other main related parts of the breaker are immersed in water and mud and deposit stains, it will cause early wear and tear of the breaker. If you need to work in water, you need to install special equipment for underwater operations. When the breaker is operating underwater, compressed air must enter the impact chamber at the front, refer to the water equipment manual. This part of the document is independent and provided with the underwater operating equipment.

The crushing and impact angle of the mini excavator is 90 degrees. The crusher should maintain a 90-degree angle to the surface of the broken object, that is, it should be vertical to the surface of the broken object, and keep it as close as possible at all times. If the angle of the crusher is tilted, the crushing head will slide away from the surface of the broken object, which will cause the crusher to be lateral. The force will cause the drill rod to wear or break faster, and even cause the piston to be damaged. Cannot be used as a sledgehammer. Place the drill head on the ground before starting. Never try to use the breaker as a sledgehammer to break objects. Doing so will cause damage to the breaker and the machine.

Do not use the breaker itself or the drill rod as a lever. Do not pry any object from the side of the breaker itself, otherwise the breaker will be damaged and destroyed. Please do not use the drill rod as a lever to pry any object, otherwise the drill rod will break. Leverage operation is the biggest cause of breakage of drill rods. When mini excavator crushes, do not use the breaker to move the broken objects. The hydraulic breaker is not designed for this purpose. Do not use the breaker or drill rod to roll or push objects or change the position of the equipment. This can cause serious damage to the breaker and equipment.

The mini excavator breaks the pieces to prevent empty hitting. The blow should be stopped after the striking object is broken. Otherwise (strike when the drill rod is not fixed), there will be a collision between the piston and the drill rod, between the drill rod and the drill rod pin, and between the drill rod pin and the front sheath, causing the drill rod, drill rod pin, and front sheath to become damaged. damaged.

When the mini excavator breaks the breaker rod into the broken object, the blow should be stopped. It is strictly forbidden to hit the drill rod when it penetrates the broken object and enters the inner layer. Therefore, the drill rod cannot break the object at this time, and if the blow is continued, it will cause an empty strike. The drill rod enters the material without breaking the material, which will cause the drill rod to become hot and red and lose its hardness. As a result, the drill rod will wear faster. Do not use soft objects such as soil as crushing objects. When the drill rod is inserted into the broken object, it will shake back and forth in order to pull it out. At this time, the front and back inclination should not be greater than 5 degrees, otherwise the drill rod will break.

The above is the crushing method of a mini excavator. I hope it will be helpful to your crushing operations. If you want to buy a new excavator, please contact LEMG Heavy Industry.
