New customers who buy Zendee crushing hammer often reflect on how the crusher is prone to problems, whether it is the problem of the machine or the operation of the crushing hammer? Let's analyze how to avoid this.

Stop working when the hose vibrates violently.

Check whether the high-pressure and low-pressure hose of the breaking hammer of the excavator vibrates excessively. If there is such a situation, there may be a fault, you should immediately contact your local authorized service department for maintenance service. Further check whether there is oil leakage at the hose joint. If there is oil leakage, tighten the joint again. As shown in the figure, it is necessary to visually check whether the steel drill rod has allowance during the operation. If there is no allowance, it must be stuck in the lower body. The lower body should be removed to check whether the parts should be repaired or replaced.

Stop homework (avoid excessive air attack).

Once the stone is broken, the hammering shall be stopped immediately. If the air hammer is continued, the bolt will be loose or broken, even the excavator and loader will be adversely affected. When the breakdown force of the hammer is improper or the steel rod is used as a crowbar, the phenomenon of air strike will occur. (the sound of the breaking hammer will change when it hits the air)

Zendee crushing hammer can not be used to move stones.

As shown in the figure and, do not use the broken hammer fitting steel bar end or support side to move or push the stone. At this time, the oil pressure comes from the excavator, loader boom and jib. Bucket, shaking or sliding operation, so the boom and the boom will be damaged. At the same time, the bolt of the breaking hammer may be broken, the bracket will be damaged, and the steel drill rod will be broken or scratched. It is necessary to avoid using the hammer to move the stones. It is specially pointed out that the steel drill rod is inserted in the stone, and the excavation must not walk.

Do not use the steel drill rod as a crowbar

As shown in the figure, if the steel drill rod is used as a pry bar, the bolt and steel drill rod may break.

Don't go south for more than a minute.

When hitting hard rock, strike at the same place for no more than one minute, and then switch to another place.

Long time percussion operation will cause the oil temperature to rise, which will lead to the damage of the steel drill bush and the wear of the steel drill rod progress.

For the long, hard stone block, can be broken at its crack or end, so relatively easy to break the stone.

Zendee crushing hammer should work at the normal engine speed.

When the engine speed exceeds the rated value, the impact force will not be increased, but the oil temperature will rise and the equipment will be damaged.

Zendee breaking hammer cannot work in water and mud.

Do not use a breaking hammer in water or mud, otherwise the piston or similar parts may rust and cause permanent damage. If you need to work in water or underwater, you should order a special underwater hammer.

Don't let the hammer fall directly to break the stone.

If the crushing hammer directly falls to the gravel, the crushing hammer or excavator will bear too much force, which will easily damage the excavator and loader parts.

When the oil cylinder rod on the excavator boom has the maximum stroke, please do not strike.

When the cylinder rod stroke of excavator and loader is maximum (the cylinder rod is fully extended or retracted), it will damage the oil cylinder and all parts of the excavator and loader.

Do not use the breaking hammer to suspend objects.

Do not use ropes to hang objects on Zendee breaking hammer, rack and breaking hammer pick. As a result, the breaking hammer, support and steel drill rod can be easily damaged, and this kind of operation is also very dangerous.

It is specially pointed out that in winter, the engine should be started for 5 to 20 minutes for preheating, and then the crushing hammer can be operated.

The engine should be preheated according to the operation and maintenance instructions of excavators and loaders, and the crushing work should be carried out at low temperature, so as to easily damage the various parts of the hammer, such as pistons, seals, etc.

After reading the above precautions, I believe you have a better understanding of Zendee crushing hammer. The above problems are summarized by Xiamen yonglianfeng machinery and equipment in combination with several customer cases. If you have other problems, please call us for advice.
