We all know that excavator pile hammer basically work outdoors because of their work content, and some of them are not paved roads, and the dust is also serious during drilling operations, and it is easy to be contaminated with sand and dust, which will continue to rise over time.
The breaker hammer is an important accessory of the excavator, and the correct use of the breaker is crucial to the life of the excavator. This time, the editor brings the correct selection method of the breaker drill rod.
First remove the breaker return pin and rock breaker drill rods pin, reinstall the rock breaker drill rods, and insert the rock breaker drill rods
The operation of the excavator sheet pile driver can be completed by one excavator driver. The same set of equipment is used for piling and pulling. The operation between piling and pulling is fast, with good mobility, and there is no need to disassemble and assemble the transfer site.
The heat treatment process of the breaker hammer drill rod is preferably quenched as a whole and tempered in sections. The HRC hardness value of the impact part of the drill rod is 56-58, and the HRC of the impact part of the piston is 45-48.
The hydraulic breaker drill rods is the tool used to connect the drill bit and the rock drilling in the tunnel engineering.
The grease nipple of the big arm and bucket is lacking, resulting in poor lubrication of the pin shaft and excavator bushing of the working device, and abnormal dry grinding noise.
At the same time, the solid self-lubricating bearings has superior performance in use and strong product competitiveness, and it will definitely be more fully applied in the use of construction machinery in the future.
The application of self-lubricating bearings in hydraulic excavators has 12 application parts of self-lubricating bearings, which are mainly used in booms, sticks, chassis running mechanisms, body parts, hydraulic components and other components.
There are defects inside the broken hammer chisel diameter material, and the vacuum degassing effect during the steelmaking process is not ideal, resulting in the generation of bubbles in the material.
In the process of formulating the excavator long reach arm, be sure to inform the manufacturer what kind of working conditions I want to do, whether it is demolition or deep excavation.
Is your excavator oil cylinder always broken? See if you have these five wrong operations. 01Walking without complete recovery of the working device When the working device is not fully retracted, the bucket can easily hit th
