The tipo KT9C integrated open-air DTH drill rig es un equipment drilling avanzada altamente efficient y energy-saving carefully desarrollado for small y medium-sized open-pit mining, quarry y infrastructure projects construction. En r tiene las ventajas of del KT7C drill rig, y en el same time enjects nuevos conceptos de diseño, por lo que tiene m cualquier character características:
1. The overtodo el diseño es more r razonable y m fácil de mantener.
2. Equipado con motor diesel Cummins China III para meet el requirements nacional for emissions y environmental prprotection.
3. The hydraulic pressure adopta un sistema multi-pump relativamente independiente r y elim pone la válvula de derivación, que es more estable.
4. Equipado con Dr. 17/17 alta single-stage de Tang Yan air pressure screw compression system, tiene una ventaja overwhelming compared con el medium air pressure integral drilling rigs of other manufacturers.
5. The rocker – link boom system incr alivia el ángulo de inclinación luff, puede meet las necesidades of different worposiciones de reposo undere75367536 el lateral arrangement of el carriage m hace el working field better.
6. The two-speed propulsion systemm composed of a cylinder – plate chain y two-motor two-speed gyrator can meet the 7536rem
7. The rig tiene un bajo center of gravity y una distribución equilibrada. Está equipado con un heavy-duty "four ruedas y una correa", un large torque walking motor con mechanical/hydraulic doble brakes, y el frakes, y el frakes37097028eveling estable el nivel automático y el frakes720970490
8. The rig drilling está equipado con un system de recogida de polvo dry efficient two-stage, que improves greatly la environment working y conforms al concepto of energy-saving y environmental protection.
