TWH 022 - Bucyrus 49HR Blast Hole Drill
Model Review May 2008
Detail (continued)
The work platform area is surrounded by convincing handrails and chains, and fine mesh walkways, and there is a drain cover at the foot of the mast. The front stabilisers have control boxes with wiring, and hydraulic lines. Following the walkway to the rear leads past a detailed door and warning notices to a set of stairs which has excellent mesh treads.
At the rear there is a large cable drum complete with realistic thick feeder cable. There is also fine electrical wiring leading to the automatic pinning system on the mast stays. A short ladder leads into the open entry to the radiator room which has a large cooling fan inside. Moving along the side opposite the operator's cab there is a large fine mesh screen at the main radiator and further towards the front a number of opening doors reveal equipment and a another radiator.
Inside the main body there is a detailed motor and some excellent electrical switchboard equipment, and the floor has some non-slip panels.
The mast is a very good heavy lattice construction which includes toothed racks for the drilling equipment drive, and a ladder which is complete with safety cage. At the base there is a plethora of wiring and hoses which drive the winch and lead up to the drilling motors. The drilling machinery is very detailed with motors to drive the drill rods and the pinion drive that pushes the drill down. The model is completed with some metal drill rods which have finely detailed drilling heads at the end.
