What Are The Precautions For Replacing The Track Roller?
What is track roller?
The track roller mainly serves as a support and is located between the lower surface of the left/right beam of the underframe and the crawler. Depending on the tonnage of the machinery, there are usually 5-10 track rollers on each side.
Steps for replacing the track roller:
① Clean the mud and debris from the walking rack and park the equipment on a flat area.
② Use a wrench to loosen the pressure relief plug of the tensioning cylinder of the traveling frame. And do not loosen it more than one turn to prevent high-pressure grease from spraying out and injuring people.
③ Use a working device (boom cylinder) to support the vehicle body, lift the track shoes. And use a pneumatic wrench to loosen the screws on the track roller cover, but do not completely remove the screws.
④ Lift the boom oil cylinder. Lower the track shoe. Support the track shoe with the track roller. Loosen the screws and remove the cover. Support the vehicle body again, and lift out the track roller.
⑤ Install the track roller in the disassembly sequence. The roller screws are coated with copper powder to prevent rust. After screwing in place with an air wrench, the weight gauge (torque tool) can be adjusted to the specified value to add weight.
⑥ After injecting high-pressure grease into the telescopic cylinder of the traveling frame, measure the front and rear travel to the standard value.

1. Check the oil level of each running assembly before drilling.2. Check all connecting bolts and fastening studs, and tighten them in time in case of looseness. 3. Check whether there is oil leakage, water leakage and air leakage in all parts.
Track shoes are common walking parts of construction machinery, and are also one of the main parts that are easy to wear. They are widely used in crawler crane, piling machine, bulldozer, and excavator.
1. One Machine Can Be Used for Multiple Purposes to Realize Multiple Drilling Methods. Firstly, the design of large pile hole and foundation construction drilling rig makes full use of hydraulic transmission technology, adopts modular combination design method, and realizes multi-purpose of one machine without changing the main machine, so as to meet the adaptability of large construction machinery to different construction methods.
1. When unwinding and installing the wire rope In order to prevent damage to the wire rope lay structure, the correct method should be adopted; In addition, when winding the wire rope to the drum, do not make the surface of the wire rope with sand. So as not to aggravate the wear, affect the life of the wire rope.
1. During construction on the soft soil ground, it is easy to attach soil to the track and track link. Therefore, the track shall be slightly loosened to prevent the attached soil from exerting abnormal stress on the track link. 2. When constructing on the ground with pebbles, the track should also be slightly loosened, so that the bending of the track shoe can be avoided when walking on the pebbles. 3. When constructing on firm and flat ground, it is better to adjust the track slightly.
XCMG XR550D rotary drilling rig consists of telescopic crawler undercarriage, large diameter swing bearing, full single row winch wire rope, self lifting foldable drilling mast, telescopic Kelly bar and other components.
Firstly, the auger drilling rig is simple in structure and fast in installation. The operator only needs to connect the drill pipe with the power head. Drill pipes are usually installed and used according to different conditions. The rotary drilling rig has more components than the auger drilling rig. In terms of Kelly bar, interlocking Kelly bar, friction Kelly bar and combined Kelly bar are mostly used, which can be directly put into place during operation.
Rotary drilling rig is a kind of construction machinery for soil borrowing and bored pile, which is widely used. What do you know about rotary drilling rigs that have been used for so long? What are its main components? You know what?
