Compared with hydraulic drilling platform, the drilling function is similar and cost-effective.
The drilling speed of pure rock drilling for hydraulic drilling
machine is three times faster than that of the same magnitude pneumatic
drill.
Low energy consumption, about 1/3-1/4 of the same magnitude pneumatic drill.
The long service life of the drilling machine for the hydraulic
drill and the less consumption of the drill parts, and the low cost of
drilling operation.
The hydraulic drill can adjust the impact energy according to the rock condition to obtain the best drilling effect.
Excavator mounted rock drilling attachments are designed to be used in various job sites such as drilling and blasting, quarrying & Mining, rock bolting, rock and concrete demolition, construction works, etc. ProDrill rock drills’ percussion hour to engine hour ratio is exceptionally good at 60 %, which is substantially higher than what can be achieved with conventional drilling rigs. This is best proven in difficult conditions where other solutions fail to drill holes without the exceptional reach of the excavator’s boom. Besides demanding conditions, ProDrill Excavator Drill can also be used as hydraulic rock splitter to demolish over sized rock bad and huge concrete building removal.

3.HC20 Excavator Mounted Rock Drill :
Feathers:
1 .HC20 Excavator Mounted rock drill suit to the 15-20 tons excavator mounted machines.
2. The rate of the Pump can reach 200L/min, drilling diameter 30-50mm, 3m or 4m depth per time drilling.
3. Drilling speed: 3-5min/m for hard rock, 1min can drill 1m depth for soft rock.
4. Excavator mounted rock drill can use the same type of hydraulic oil pipe line as hydraulic breaker.
4.Remarks:
Excavator mounted drills can increase itsfunction , one excavator can used for multi use , drilling and blasting
Excavator mounted is to use crawler moving, andstir hand function, for mining and construction,
Site is different, capacity of crawler moving isbetter than normal drill rig, installation and unlock is very easy, similar with hydraulic drifter fixing, and hydraulic rock drill drilling speed is 3-5times than pneumatic drill , one time drill depth is 3 meter, suitable forsmall –hole drilling blasting at rock hardness of 7.6HRC, drilling time is 6-7minutes, if by pneumatic drill need mini 30 minutes,
France Montabert HC20, there are two drill rod, one hex, and thread type,
(1) Hex. Taper drillrod cost cheaper, only disposal after use finish,
(2) Thread extensionrod for extension use, T38 is a choose,
