Micro drilling rig,water well drilling rig

UMR8 is a newly developed multifunctional drill rig for versatile engineering applications e.g. anchoring, micro piling, jet grouting etc. having a complete range of adaptability in the field of foundation construction, tunnel construction, geological survey and slope protection construction.

 

1.genuine multi-functional drill rig for versatile engineering applications including anchoring,micro-pile,soil-nailing,tie-back,jet grounting

2.with Eurodrill hydraulic drifters,the drill rig is easily adaptable to varied tasks,and the drilling efficiency is 3-5 times faster than other normal rigs.

3.Cummins 4BTAA3.9 engine with more power,high-effiency and easy maintenance

4.double-motor and chain system enables the crowding and extraction speed much higher

5.modern load-sensing system considerably improves the system efficency.

 

 

FEATURES

Undercarriage

1. World famous brand Commins diesel enginewith aftersale service offices around the world makes maintenancemore convenient.

 

 

Engine

 

Sound-proofed power pack.

 

Diesel engine Cummins 4BTAA3.9-C125

 

Rated Power: 93 kW @ 2300 rpm.

2. Uniqueoutrigger structure, reasonable gravity distribution and lower ground pressure make UMR-6 work with great stability.

3. Integrated electronic control system combines the engine and hydraulic pump control, the rig logical control and fault diagnosis system, which makes the engine automatically adjusts the speed to power and optimizeoperation mode.Even under extreme conditions, it alsocan output maximum torque stably to prevent engine flameout.

Working devices

1. The first slewing ring fitted on base machine enables drilling parallel to the tracks up to +/- 90°.

The second kinematic allows to achieve an overall mast rotation equal to +/- 180°.In order to increase the versatility of the drilling unit, UMR-6 is equipped with telescopic boomand sliding mast withvariable stroke.

UMR-6 can set the drilling directs in full range which are able to meet the construction requests in both open air and tunnel.

2. With Hydraulic clamp & breaker which can reduce the labor and enhance the labor efficiency.

Rotary head of large torque with two grades is equipped on UMR-6, which can realize various drilling processes.

3. Optional drilling tools:

Drilling rod

Casing tube

Drilling bit

Once drilling in the unstable formation, UMR-6 can drill the hole with the help of casing tube in high drilling efficiency and high quantity.

 

Movements

 

 

Hydraulic system

1. Main pump is with control in constant power. Main oil circuit system is with load sensing, hydraulic pilot and proportional control. The Hydraulic system features by the quick response and low energy consumption.

2. The cylinder with balance valve enables the working device and mast to move in a steady speed and avoid hydraulic shock in operation.

 

Hydraulic system

Main pump (variable axial piston type with load sensing) delivery: 145 l/min. (max. set pressure 260 Mpa).

Service pumps delivery: 78 + 37 + 32 l/min.

Oil tank capacity: 230 l.

 

Control system

1. Intelligent fault detectionsystem which displays the states of each executive parts and logic interlock system can avoid the misoperation risk.

2. Handles for hydraulic control setting in different regions are flexible and convenient, which can also avoid the misoperation risk of the driver.
