Tunneling jumbos refer to rigs used for underground excavation projects such as underground mine tunnels, railway and highway tunnels, and hydraulic culverts. It can also be used for drilling bolt holes, filling method or room and pillar mining blasthole. The hole diameter is 25-64mm, and the hole depth is 1-5.5m, often 2.5-4m. It is suitable for the tunnel section of 3.2-150m2. The selection of the tunneling rig is mainly based on the roadway section and the driving speed, and at the same time, factors such as the turning radius of the roadway and the support method must be considered.

HWS Series Constant Temperature &Humidity Chamber
I. Application Overview Widely used in medicine, textiles, food processing, biological engineering and other tests and industrial products of various temperature and humidity tests.
HWS-400 constant temperature and humidity box II. Features:
1, using a mirror stainless steel liner, easy to clean around the semi-circular, adjustable shelf spacing.
2, using a double door structure, good insulation properties. The inner door adopts an all-tempered glass door, which opens the outer door and does not affect the temperature inside the box when the inside condition is observed.
3, high-precision, large-capacity humidity generator. Ensure that humidity control occurs quickly, with high accuracy and low fluctuations.
4, the original French "Taikang" closed compressor, configuration delay start. High and low pressure multiple protection.
I.Applications:
It is applicable to humidity testing in the medicinal, spin, food and biology and so on.
II.Feature:
1.Shelves inside the chamber are easy to detach and convenient to wash ,the henght of each shelf can also be adjusted.
2.There is a layer of toughtoned-glass offr with sealing rubber as the inner lay of the outer door for convenient observation of the in-incubator temperature.
3.High precision and large capacity humidity apparatus, which be sure the humidity quickly and low wave.
4.Compressor from French “TaiKang†.which is whole closed .The system was equipped with the function of delay-start and high/low pressure protection
