The type KT9C integrated open-air DTH drill rig est un très efficient et energy-saving equipment de drilling avancé carefully développé for small et medium-sized open-pit mining, quarry et infrastructure projects de construction. Il inher ses avantages of le KT7C drill rig, et au same time injects de nouveaux concepts de conception, donc il a m tout characteristics :
1. The overtoute la disposition est more rraisonnable et facile à mmaintenir.
2. Équipé du moteur diesel Cummins China III pour meet le national requirements for emissions et environmental protection.
3. The hydraulic pressure adopte un r relativement indépendant multi-pump systèmem et eliminates la vanne de dérivation, qui est more stable.
4. Équipé de Dr. 17/17 single-stage haute air pressure screw compression system de Tang Yan, il a un avantage overwhelming compared avec le medium air pressure integral drilling rigs of other manufacturers.
5. The rocker – link boom system incr facilite l'angle luffing, peut meet les besoins of different wo753675755king positions unde36735575 le lateral arrangement of le carriage makes le working field better.
6. The two-speed propulsion systemm composed of a cylinder – plate chain and a two-motor two-speed gyrator can meet the r7equi3139016701155e two-speed gyrator can meet the r7equi3139016701155e
7. The rig a un faible center of gravity et une distribution équilibrée. Il est équipé d'un -duty " four roues et d'une courroie ", d'un large àrque marche motor avec mechanical/hydraulic double brakes, et du fra7201599070e un dispositif de mise à niveau me me
8. The drilling rig est équipé d'un two-stage de efficient collecte de poussière dry system, qui improves greatly la environment de working et conforms au concept of energy-saving et environmental protection.
