China DT1-14 Drilling Jumbo: High-Efficiency Narrow Tunnel Machine from Reliable Suppliers and Factory
Product Introduction
Varies of drifters can be selected to install in the drilling jumbo. Except chassis, this machine has almost the same configuration with wheel type drilling jumbo. The applied working section is 2.2×2.0m and 4.65m×3.75m, the gradeability is less than 15°, the tramming speed is 2.4km/h.
Features
Hydraulic system
- Adopts direct drilling control system and manual four-way handle to control the translation of the big arm, with anti-sticking function and stepwise pressurization system.
- Oil tank level higher than pump avoids cavitation of oil tank.
- Hydraulic turbine gear box and spiral oil cylinder form cross joint for drilling in tunnel face, top, side, and bottom slopes without limitation.
- Multiple filtration system ensures cleanliness of oil and decreases malfunctions.
- Reasonable pump flowrate and high efficiency water cooler maintain optimal oil temperature under heavy duty work.
Translational Drilling Boom
- Mechanical translational boom keeps feeding beam parallel for quick, accurate location and parallel drilling without manual calibration.
- Rectangular section design for stability; rotation motor allows feeding system to rotate ±180°.
Cable reel
- Special designed cable reel for flexible collection, laying, and higher automatic safety levels.
Applications
The DT1-14 is specifically designed for use in underground mines with narrow tunnels.
