CYTJ45B Hydraulic Drilling Jumbo (a wheel type, electric powered, single boom jumbo) is mainly used for tunneling construction in small sized tunnel of metal mine and other underground engineering. It is designed with an advanced hydraulic drilling system with an anti jamming device, which has features of fast drilling, high efficiency. Because the jumbo has compact structure and good mobility performance, it can improve work environment and efficiency as well as quality.
This series hydraulic drilling jumbo has a high level drilling system, and an advanced drilling functions in the field ( including: collaring and full power drilling function, anti jamming function by means of rotary pressure controls feeding force, anti free impacting by feeding force is related with drifter’s impacting energy, hydraulic buffering function that backed energy can be absorbed effectively), that insuring a better drill tools life. It is equipped with a lot of warning protection devices such as low oil level, high oil temperature, oil filter blocking, no impacting if no oil lubrication etc. Besides, the jumbo is equipped with a four-wheel driving chassis with features of articulated steering, powerful and strong gradeability that make the machine can travel safe and fast in small tunnel, and insured it with a good view and stability of the jumbo.
