TGM-u hydraulic motor pushers
Pushers are intended to control rail switches in gaseous and dusty coal mines requiring the use of underground explosion-proof electrical equipment. They may be also used in other branches.
TGM pushers may be used in gas and coal dust outburst hazardous mines, under a shelter on the surface in the following conditions
- ambient temperature varying within minus 40 to plus 45 °С;
- environmental air relative humidity up to 100 % at a temperature of 35 °С;
- atmospheric pressure varying within 84 to 106 kPa (630 to 800 mm Hg);
- dust content up to 1,600 mg/m;
- vibration at installation locations with a frequency of 5 to 120 Hz:
- with the maximum vibration displacement of 0.25 mm at a frequency up to 45 Hz and maximum vibratory acceleration of 20 m/sec2 at a frequency of 45 to 120 Hz.
