An impressive looking model.
The Sandvik LH621 Underground Loader is specially designed to work in conditions of restricted headroom and can work in tunnel sizes of 5.5m x 5.5m and larger.  The operating weight is nearly 57 tonnes and it can travel with up to 21 tonnes of material in the bucket.


The model comes in a high quality Sandvik box which includes some basic information about the real machine.  The review model had no defects or missing parts.

There is no information about the model and the only assembly required is to fit two light clusters on the loader arms.


The tyres are large and particularly chunky and have a very good rubber feel, and the hubs have good detail.  Underneath, the main transmission elements are modelled but otherwise it is plain.

The engine area is a heavy casting and finer details such as the access ladder and handrails are solid rather than authentic.  However the plastic engine is visible and looks good.  At the rear there is a plastic grille, the lights are painted and there are chevron markings.

The cab casting is good and a seat is just visible inside.  At the pivot point there is a bank of hydraulic lines.

The loader mechanism is particularly robust and additional detail is provided by plastic elements such as light clusters and other parts around the front wheels.

The bucket is impressive with good casting detail including the teeth.


The rear axle oscillates and each wheel turns independently.

Steering is achieved by movement at the pivot point and the model can very nearly replicate the angle achieved by the real loader.

At the rear the grille opens allowing the cooling equipment to be seen.

The loader mechanism can lift to a realistic height and the tipping angle of the bucket is excellent.  The cylinders are stiff enough to hold any pose.


This is a strong heavy model which sets the right tone bearing in mind the nature of the real machine.  The paintwork and graphics are very good. 


The price reflects the high metal content and is good value.


The Sandvik LH621 is an impressive model and is a worthwhile addition to the range of Sandvik miniatures.  It is certainly recommended.


The model first appeared in 2009.
