PAO NPP VNIIGIS traditionally work hard on the ore mining, conducts scientific research, experimental and methodological and geophysical work in the area of ore, coal and geological engineering , as well as for production of geophysical line, including design and manufacturing of industrial standards (teams) of new and redesign products.
OOO OZKO VNIIGIS subsidiary enterprise produces well-logging truck hoist for the ore mining.
Well-logging truck hoist for the ore mining has unique features. As a rule, the well depth is small (up to 2,000 meters). The chassis used for these performances is mainly short based (URAL 4320-1151-41, KAMAZ 43114, GAZ 33081 SADKO, GAZ 27057(all-wheel drive Gazel), UAZ 3309). The winches are of two types: with electrical and mechanical drive.
WLTH 2 with mechanical winch drive
is produced on KAMAZ 43114, URAL 4320-1151-41. The winch with mechanical gear from the power takes-off device.
Well-logging truck hoist with the winch electrically operated
Recently, the production volume of the well-logging truck hoist with the winch electrically operated has increased. The applied motor gear SITI (Italy) and frequency drive of the company “SEW-EURODRIVE Gmb H&Co KG” (Germany) allows for pulling and running operations according to the demand conditions of the performance specifications, keeping pulling power regardless of the speed characteristic. The well-logging truck hoist is produced on different kind of chassis. Electric supply is taken form an external source and from the generator unit.
