Introduction

1.sizes：7,370x2,360x2,560mm and 6050kg.

2.Application: crawler mounted drilling rig is suitable for mining, quarrying, railways, transportation, water conservancy and building materials. Drill medium-deep blasting holes for military and other open-pit projects and carry out high-efficiency rock drilling operations. It is also widely used in anchor bolt support, channel excavation, and drilling operations in sewerage projects.

3.Ability: Professional R&D capability, capable of making reasonable modifications based on different customer demands.

Details

Crawler mounted drilling rig to cater to the market demand the development of a new type of DTH drill rig, the excellent product performance, flexible operation, complete function, adaptability, has high cost performance. Crawler mounted drilling rig is through the mechanism of energy conversion engine driven hydraulic pump, can convert mechanical energy into hydraulic oil pressure (pressure 20.6 MPa or higher), through the closed-loop oil transfer to the actuators. Double rotation directional valve controlled motor to realize stepless variable speed (0-120 RPM), push oil cylinder precision adjustment wob DTH drilling mode impact - rotating composite rock impact device directly into the bottom of the hole hammer rock (> 1800 times/min), synchronous rotary bit cutting rock mass. Enhance the torsional strength, triangular drill pipe diamond bit for hard rock (rock hardness f 10 or less). Slag discharge with high pressure air blow out by hollow drill cuttings, and protecting with pipe drilling process to prevent the collapse hole water-eroded cave area.

FAQ

Q: Abnormal pressure fluctuations in the hydraulic system?

A: Reason: hysteresis (pressure relief valve card < 18 mpa) or hydraulic pump discharge (volumetric efficiency < 80%) solution: clean/replace relief valve, wear testing pump body sealing and replace components.

Q: Is the power head rotating weakly?

A: Check items: the guide oil plug (pressure < 1.5 MPa) or the motor bearing damage (sound) measures: dredge the guide line or replace the hydraulic motor.

Q: What should be noted when starting up for the first time?

A:Check the hydraulic oil tank (liquid level in oil standard about two-thirds required), crawler tensioning degree (prolapse 30-50 mm) and battery voltage (24 v or higher). No-load running for 10 minutes, observe whether the hydraulic system pressure is stable (20.6 + / - 0.5 MPa.
