1:50th Scale Sandvik Di600 DTH Drill
Presented here is the first Sandvik model to be produced by BYMO scalemodels. The Di600 down-the-hole drill is used for drilling blast holes in quarry applications and the 1:50th scale model has accurately captured all the details of the full sized machine.
The individually linked metal tracks are freely rotating with detailed drive sprocket and the track frames have two small hydraulic pistons fitted which simulate the tilting ability of the chassis which is non-functional on the model.

The low positioned cab features a front and roof mounted debris screen with integrated front facing work lights and warning beacon. The cab interior has been accurately modelled with operator seat, joystick controls and side mounted display console all visible through the large windows. Access steps have been added to the side of the body with a single step giving access to the cab with accurately scaled grab rail cast into the frame and rear view mirror with reflective surface also fitted. |

The main body casting has been very well done with plenty of side panel details and accurately modelled rear housing with rubber discharge pipe, authentic markings and a good paint finish. The two tone orange and grey colour scheme has been reproduced which give the model a very impressive appearance.

The upper cooling grills appear to be photo etched plates which adds to the level of detail, as does the silver painted cylinder tank and flexible hydraulic piping to the rear dust suppressant motor. |
The model can be posed in a travel configuration with the drill mast folded along the side of the engine housing. There is even a locking bar mechanism fitted which appears to lock the boom into position, as seen in the picture below right, which is another example of the amount of detail captured from the real machine.

The main drill mast consists of a highly detailed main casting with additional detailing, including the rod transfer mechanism glued into place. The main drill rod is non-functional and cannot be traversed along the length of the boom but I don't think this detracts from the model. |
The main boom is connected to a joint which allows the drill mast to be angled and the hydraulics are just about stiff enough to hold the drill mast in position. Flexible piping has been fitted between the drill tip and the main engine housing which has a very realistic appearance.
The drill tip is hidden inside the dust suppressant cone and this area of the model looks very realistic. The main boom foot has a knobbled surface to give steady footing and the rod holder is populated with 6 extension rods which cannot be removed. |
The mast does have the ability to slide along the boom support and a hydraulic piston has been fitted which allows the extent of movement to be positioned. There is a small piston which controls the angle of the mast and the main lift hydraulic has a guard with location pins which come together as the boom is lowered which is a nice touch.
This is an excellent model of an interesting machine and it is about time that more drill and underground equipment models were produced. The paint finish is very good with accurate placement of the sefaty and warning labels and the use of flexible tubing for the dust extraction and control hydraulics adds greatly to the realism.
