Sandvik TH550 Underground Articulated Hauler
"Updated Design"

Presented here is the updated version of the 1:50th scale Sandvik TH550 underground articulated hauler from Conrad. This version has the new yellow safety features with a completely re-designed rear tipping body. The model is now available from the Sandvik Online Shop. The model compliments the previously released LH621 underground loader and MT720 roadheader models very well.

The articulating frame has been accurately replicated with good crisp casting of the components showing the various structural details. The cab interior has been included although it is a little difficult to see through the small windows and the rear screen has a protective grill with integrated rear facing work lights.

The front and side opening engine grills reveal the moulded cooling systems with twin fan grill detailing which is a nice touch on the model. Self fit rear view mirrors are supplied with the model and need fitting to the holes in the cab frame and upper body.

Four large work lights with silver painted lenses are integrated into the sides of the engine compartment with two smaller lights integrated into the front grill with a simulated front towing hitch. In front of the cab is a compartment holding a large fire extinguisher while small compartments are also found on the opposite side, complete with small cast latches.

The upper surfaces of the engine compartment have a chequered patterned finish with the chromed exhaust pipe rising from within the engine bay. Hydraulic hosing has been added across the articulating joint with access steps integrated into the body casting behind the front wheel with plastic safety handles, all painted in the new yellow safety colours.

The driveshaft to the rear axle is mounted above the chassis frame to protect it from getting damaged by rocks and debris and this has been added to the model, complete with protective rock guards on the underside.

The photo-etched grill covering is a nice and somewhat unexpected addition from Conrad with the exhaust system having nicely detailed angled pipe ends with a textured main engine cover panel. The paint finish is excellent throughout with highlighted components and crisp printed markings.

The dump body has a more rounded shape which has been accurately modelled with all the re-enforing structure detail added to the underside, including the hinged safety bar mounted to the underside of the body which folds down during maintenance.

For this version, the body is narrower with a more curved design to allow better discharge of the material and fits to the rear chassis which is the same as the first version of the model. Both are pictured below showing the different designs.

The body lifts to a very good height while the articulating frame offers a good amount of steering movement with the front axle pivoting to simulate the suspension mechanisms of the truck. The large tyres have a deep moulded tread pattern which looks authentic with plastic wheel hubs showing all the fixing bolt detailing.

This is a good addition to the growing range of Sandvik replicas with a nice heavy weight typical of a Conrad model. The updated version is the perfect partner for the Sandvik MT720 roadheader model (pictured below)
