Slewing System
In the slewing platform of compact crawler CZPT, a welded framework provides higher rigidness. The base of the system is related with the base plate by way of a slewing pearing. In the middle, there is a robotic arm and slewing reducer, which with the slewing pearing composes a slewing system. On the correct of the slewing system, hydraulic oil ank and major valve are put in. On the still left is running cap, equipped with a relaxed seat, a protective roof and pilot valves.

Going for walks Method
The total strolling system is composed of crawlers, foundation plate, going for walks travel unit and crawler stretching gadget. That is why the CZPT exhibits a excellent ability in climbing slope and turning sharply, as effectively as enjoys low floor stress and stable walking. The put in two crawlers are independently pushed by two driving units, ready to freely walk, swerve, rotate and far more.

Robotic Arm
This unit is mostly used for digging, lifting, discharging and a lot more.

CZPT Technique
Primary components consist of main oil pump, gear pump, hydraulic motor, hydraulic cylinder, main valve, pilot valve, oil filter, cooler and oil tank

CZPT Method
The explosion-proof motor distributes electrical power of 37 KW to each and every device of this CZPT and makes certain a typical and very efficient operating.

The compact crawler CZPT is outfitted with a vacuum electromagnetic starter, which is most usually employed to handle and protect the primary motor. Not only that, the CZPT also tends to make use of an built-in protective gadget, which helps prevent the lighting technique and bell from quick circuits and electrical leakage.

Quick CZPT:

Quick CZPT are also called Rapid Change Connector, primarily for CZPTs to boost the performance of substitution among the shift and the doing work areas this kind of as the bucket and the loosening, when functioning.

Positive aspects:

The device is appropriate for the nicely, roadway and slope of coal mine, metal ore and non-metallic ore with considerably less than 14. Excavation operation of loading rock, bottom cleaning and permafrost in inclined lane excavation. The equipment has the pursuing qualities:

1.In comparison with the conventional artificial clear base, the use of this machine in the important cost savings of labor fees at the same time, enhance the performance of operations, improve the functioning setting.

two.The operator is functioning under the protection of the roof, which is conducive to protected production.

three. Compared with the classic diesel electricity modest CZPT, due to the use of electric hydraulic method, so it has the qualities of lower sound, no exhaust air pollution, more suitable for downhole use.
4. The machine has compact structure and tiny condition dimension, and the functioning gadget can be recycled in the bottom of the shaft to aid vertical downhole and nicely lifting.
five. The vehicle is compact and little in dimension, and its tail does not collide with the properly wall when it rotates, generating it far more appropriate for little underground space functions.
6. The principal action adopts the pilot valve handle, the operation is simple and straightforward, the perform is easy with out effect. Product use environmental problems:

 1) suitable for shafts far more than 6 meters in diameter, as well as a section of 4.0×4.five meters over and slope less than one hundred forty of the roadway.
two) the Rock’s Platts hardness F is less than or equal to twelve, the block diploma is considerably less than or equal to 600mm, the unfastened density is not better than one.8t/m.
3) Altitude <1000m. High altitude 1000m above the plateau environment needs to be specially designed
4)the roadway setting is -5ºC~ 40 ºC, the greatest relative humidity <90% (temperature of 25 ºC)
5),the voltage restrict deviation is 5% soil, AC frequency restrict deviation is ±1%
6)The content material of coal dust and methane explosive gas close to the CZPT should conform to the protection content material stipulated in the Coal Mine safety rules.

seven.Outfitted with hydraulic quick-modify connectors, fast change joints can be swiftly mounted on the CZPT a range of configuration components (digging, loosening, crushing hammer, hydraulic shears, etc.), can broaden the use of CZPTs, and can help save time, boost ergonomics.

Quick Alter Connector has the adhering to positive aspects: 
 1)disassembly quickly and convenient, help save time to boost operate effectiveness, decrease the labor intensity of operators.
two)There is nearly no working medium outflow when the self-styled rapid change connector is removed. The pollution of the working surroundings is reduced and the grime is prevented from moving into the piping technique, therefore strengthening the reliability of the hydraulic method.
3)Fast adjust connector by itself can be freely rotated, not only to release the set up procedure in the pipeline produced by the interior pressure, but also to defeat the operate because of to vibration brought on by the loosening.
four)the use of large-power materials, appropriate for three-45 tonnage of numerous types.
five)the use of liquid-managed a single-way valve basic safety device, to make sure protection.
